How many Crusades total have occurred in World History?

 

Short answer: There is no single, universally accepted “total number” of Crusades in world history.

• If you mean the big, numbered Crusades to the Holy Land, historians usually count eight, sometimes nine, Crusades between 1096 and 1272. (Britannica says “at least eight” and lists eight expeditions from the First to the Eighth Crusade.)

• If you count all papally authorized “crusading” campaigns, including those in Spain, the Baltic, against heretics, and against the Ottomans, scholars describe dozens of separate crusades from the late 11th century into the late 16th century, and there is no standard finite count. One defense-analysis survey, for example, notes that “dozens of Crusades were authorized every half century” after 1291 and treats the Spanish Armada of 1588 as the last crusade in this broad sense (Department of Defense, 2018).

Below, I will give you the conventional list of the nine major Crusades to the Holy Land, since that is the only “complete” list that historians use with anything like consistency.

The nine “major” Crusades to the Holy Land

Years vary slightly by author, but the ranges below reflect common scholarly usage, with support from modern reference works and teaching texts (Encyclopaedia Britannica, n.d.-a; HistoryCrunch, 2019a; Lumen Learning, n.d.; World History Encyclopedia, 2018a, 2018b, 2018c, 2018d, 2018e, 2018f, 2018g).

1. First Crusade – 1096–1099

   • Launched after Pope Urban II’s call in 1095; Western European forces captured Jerusalem in 1099 and created the first Crusader states (World History Encyclopedia, 2018a).

2. Second Crusade – 1147–1149

   • Called in response to the fall of the County of Edessa; led by kings of France and Germany, it failed to retake Edessa and accomplished little in the Levant (Lumen Learning, n.d.; World History Encyclopedia, 2018b).

3. Third Crusade – 1189–1192

   • Launched after Saladin captured Jerusalem in 1187; led by Richard I of England, Philip II of France, and Frederick I Barbarossa. It recovered some coastal territories but not Jerusalem (Encyclopaedia Britannica, n.d.-b; World History Encyclopedia, 2018c).

4. Fourth Crusade – 1202–1204

   • Intended to attack Egypt, but was diverted and ended with the sack of Constantinople in 1204, creating the Latin Empire instead of liberating Jerusalem (Lumen Learning, n.d.; World History Encyclopedia, 2018d).

5. Fifth Crusade – 1217–1221

   • Focused on Egypt (especially Damietta) as the key to controlling the Holy Land; ultimately failed and ended with a negotiated withdrawal (EBSCO, n.d.-a; World History Encyclopedia, 2018e).

6. Sixth Crusade – 1228–1229

   • Led by Emperor Frederick II; relied mainly on diplomacy. A treaty restored Jerusalem and other cities to Christian control for a time, without major battles (Encyclopaedia Britannica, n.d.-c; World History Encyclopedia, 2018f).

7. Seventh Crusade – 1248–1254

   • Led by King Louis IX of France; again targeted Egypt, briefly capturing Damietta but ending in Louis’s defeat and captivity (EBSCO, n.d.-b; World History Encyclopedia, 2018g).

8. Eighth Crusade – 1270

   • Also led by Louis IX, this time against Tunis in North Africa; the campaign collapsed after Louis died of disease soon after landing (HistoryLearning, n.d.).

9. Ninth Crusade – 1271–1272

   • Often treated as a continuation of the Eighth Crusade. Led by Prince Edward of England (later Edward I); it achieved some local military successes but did not reverse the overall Muslim advantage and is usually regarded as the last major crusade to reach the Holy Land (HistoryCrunch, 2019b; Medium, 2022).

Because of how historians define “crusade” today, any attempt to give a single total number for all Crusades in world history is inherently interpretive. In strict “numbered Holy Land” terms, you are looking at eight to nine major Crusades. In the broader sense of papally backed crusading warfare across Europe and the Mediterranean, you are looking at many dozens of separate expeditions between about 1096 and 1588 (Department of Defense, 2018; Newberry Library, 2012).

Can military personnel in uniform wear a Masonic apron?

Normally, no. A Masonic apron should not be worn over a U.S. military uniform unless the service member has specific authorization from the proper military authority. A Masonic apron is best treated as civilian or fraternal ceremonial regalia, not as a military uniform item. Masonic dress rules may vary by Grand Lodge, but they do not override military uniform regulations (Department of the Army, 2021; Department of the Navy, n.d.; United States Coast Guard, 2020).

 

The religious-apparel exception probably does not solve this issue. Federal law defines religious apparel as apparel worn as part of observing the service member’s religious faith, and DoD religious-accommodation policy addresses items tied to religious practice (10 U.S.C. § 774, n.d.; Department of Defense, 2020). Public Masonic sources describe Freemasonry as a members’ organization with no political or religious affiliations, and describe the apron as Masonic regalia or the “badge of a Mason” (Grand Lodge of Ohio, 2023; United Grand Lodge of England, n.d.).

 

Branch-by-branch practical read

 

Army: AR 670-1 allows religious apparel only under specific conditions and defines it as articles worn as part of religious observance. The same regulation also limits mixing uniform items and civilian clothing. A Masonic apron worn over an Army uniform would normally be unauthorized unless specifically approved by the proper authority or clearly covered by a valid accommodation or worship-service exception (Department of the Army, 2021).

 

Navy: The Navy rule is direct. Navy Uniform Regulations state that wearing civilian ceremonial regalia with a naval uniform is normally improper, with only a narrow academic-regalia exception. A Masonic apron over a Navy uniform would normally be improper unless specifically authorized (Department of the Navy, n.d.).

 

Marine Corps: Marine Corps uniform regulations state that exceptions to the uniform manual are granted only in writing by the Commandant of the Marine Corps Uniform Board. The regulations also state that uniform components will not be mixed except as authorized. A Masonic apron over a Marine Corps uniform would normally be unauthorized unless proper written authorization exists (United States Marine Corps, 2018).

 

Air Force: DAFI 36-2903 states that dress and appearance standards not listed as authorized are unauthorized. It also requires Airmen to maintain a professional military image and gives commanders authority to enforce uniformity. A Masonic apron over an Air Force uniform would normally be unauthorized unless specifically approved through an applicable process (Department of the Air Force, 2024).

 

Space Force: SPFI 36-2903 similarly states that personal accessories not listed in the instruction are not authorized for wear and gives commanders authority to prohibit optional items during formations, ceremonies, or events where uniformity is required. A Masonic apron over a Space Force uniform would normally be unauthorized unless specifically approved (United States Space Force, 2025).

 

Coast Guard: Coast Guard uniform regulations explicitly prohibit civilian ceremonial regalia while in 

uniform, with a narrow allowance for certain academic hoods worn over the left forearm. A Masonic apron over a Coast Guard uniform would normally be prohibited (United States Coast Guard, 2020).

 

How this should work in military lodges

 

A “military lodge” does not create a military-uniform exception by itself. The lodge may be Masonic in membership, location, or tradition. However, the service member’s uniform is still governed by the member’s branch regulations, command policy, installation policy, and any approved religious-accommodation process (Department of Defense, 2020; Department of the Army, 2021; Department of the Navy, n.d.).

 

The best practice is for members to wear civilian formal or business attire for lodge work, then wear the Masonic apron and other Masonic regalia as required by the lodge. For official military ceremonies, the service member should wear the prescribed military uniform without Masonic or other fraternal regalia unless written approval has been granted. For mixed military and lodge events, the event organizer should obtain a command decision in writing before the event.

 

For the photos circulating online, I would not call it a violation without knowing the duty status, event type, and whether authorization existed. However, under normal U.S. military branch rules, a Masonic apron over a military uniform is not, by default, authorized as wearable.

Gen X, Gen Z, and the Same Old Road with Different Potholes

One of the strange things about getting older is watching younger people go through things that feel very familiar.

As a Gen X’er, it is easy to look at Gen Z and think, “I have seen this before.” The confidence, the bad choices, the ignored advice, the belief that older people just do not understand. We had all of that too. We just did it with less internet, worse hair, and fewer cameras pointed at us.

But it would be unfair to say Gen Z is simply repeating Gen X with better phones. The world really is different now.

Gen X got to make a lot of mistakes in private. Gen Z is growing up in a world where one bad moment can be recorded, shared, judged, and saved forever. That changes things. It adds pressure that many of us did not have when we were young.

The money side is different, too. College, housing, careers, and adulthood all come with a steeper price tag now. A lot of the old advice still has value, but some of the old timelines no longer work the same way.

That is where both generations could probably give each other a little more grace.

Gen X has lived long enough to recognize some patterns. We know that some decisions age badly. We know that not every opportunity comes around twice. We know that a little patience, humility, and self-control can save a person a lot of trouble.

Gen Z, on the other hand, is trying to grow up in a world that moves faster, watches more closely, and demands more visibility than anything Gen X had to deal with at that age.

So maybe the point is not for Gen X to lecture Gen Z, or for Gen Z to dismiss Gen X as outdated. Maybe the better answer is somewhere in the middle.

Gen X can admit that the game board has changed.

Gen Z can admit that some mistakes are older than Wi-Fi.

And maybe both sides can agree on this: youth has energy, age has perspective, and life would be a lot easier if those two things showed up at the same time.

Medieval Corned Beef
British Isles - Medieval 
(Honey-basted roasted corned beef.)
City/Region: Ireland 
Time Period: c. 1100
URL: https://www.tastinghistory.com/recipes/medievalcornedbeef

Corned beef’s popularity fell in medieval Ireland because most of the good corned beef was sent overseas to England.  Pork was cheaper to raise, so many ate bacon and cabbage until the Irish Potato Famine, when many immigrated to America. The neighborhoods where they tended to move to were serviced by Kosher butchers, who didn’t have any bacon, but did have plenty of corned beef. This recipe is derived from a poem written around 1100, which describes how corned beef was prepared. The main difference between this medieval preparation and modern versions is the honey. The combination of corned beef's saltiness and honey's sweetness is so wonderful. Delicious!

“Tender corned beef…and honey in the comb, and English salt…He rubbed the honey and the salt into one piece after another.” 
— Aislinge Maic Con Glinne (The Vision of Mac Con Glinne), c. 1100

Ingredients:

4 lbs (2 kg) corned beef brisket (my brisket was only 3 pounds...)
1/4 cup (85 g) honey
1/2 teaspoon salt
(I added 1 shot of Jamison's Irish Whiskey because...)

Instructions:
1. Preheat the oven to 325°F (165°C).
2. In a large pot, cover the corned beef with water and bring to a boil. Boil for 1 minute, then drain. Repeat at least once. This process will help reduce the corned beef's saltiness. After you’ve boiled the corned beef at least twice, place it on a large piece of foil.
3. Mix the salt and the honey, then brush it generously all over the corned beef. Wrap the corned beef in the foil and place it on a baking sheet or roasting pan. Roast in the oven for 1 hour per pound.
4. 30 minutes before the corned beef is done, open the foil and raise the temperature of the oven to 400°F (205°C) to brown the top.
5. Slice and serve it forth with Cabbage Pottage.

=============================================================
Cabbage Pottage
British Isles - Medieval 
(Cabbage cooked with leeks and onions.)
City/Region: Ireland | England
Time Period: 14th Century
URL: https://www.tastinghistory.com/recipes/cabbagepottage

“Caboches in potage. Take caboches and quarter them, and seeth them in gode broth with oynouns mynced and the whyte of lekes slit and carved small”      
— Curye on Inglysch, 14th Century

Finding a historical recipe from Ireland is really hard, and finding a medieval Irish recipe is basically impossible. I started with a medieval English recipe from a few hundred years after the corned beef description. I adjusted it to match the ingredients we know were available in Ireland around 1100. The cabbage pottage is simple to prepare and has a mild flavor, though there is a touch of heat from the onions and leeks. The simplicity of the dish pairs perfectly with the complex Medieval Corned Beef. 

Ingredients:
 1 large head of cabbage, quartered
 1 large onion, chopped fine
 2 leeks, sliced into half rings
 2 cups beef broth (I ended up using 4 cups...)
 1 teaspoon salt
 1 teaspoon pepper, optional

Instructions:

1. Leeks can have dirt and silt in them, so swish the sliced leeks in a large bowl of water to clean them.
2. Combine the vegetables in a pot and sprinkle them with the salt and optional pepper.
3. Pour in the beef broth and bring it to a boil. Reduce to a simmer and cover. Cook for 20 to 30 minutes.
4. Serve it forth with Medieval Corned Beef.

Ode to Cybersecurity

The History of “Cyber”: How an Ancient Word Shaped the Digital Age

 

What’s in a Word? The Origin of “Cyber”

If you spend any time in the worlds of technology, security, or defense, you’ve probably noticed that cyber has become the ultimate prefix. We hear about cybersecurity, cybercrime, cyber operations, and even cyber cafés. But where did this little word actually come from, and why has it stuck around?

Let’s take a quick journey through history.

---

From Ancient Greece to Modern Tech

The story begins in ancient Greece. The word κυβερνήτης (kybernētēs) meant helmsman or steersman—someone who guides a ship. That idea of steering or governing is at the root of the modern term.

Fast-forward to the 20th century, when American mathematician Norbert Wiener drew on this concept. In 1948, he published Cybernetics: Or Control and Communication in the Animal and the Machine. For Wiener, cybernetics was the science of control systems, feedback loops, and communication, whether in a living brain or a mechanical device. The Greek “steersman” was now steering machines and information.

---

Cybernetics Meets Computing

As computing matured in the 1960s and 70s, the language of cybernetics seeped into computer science and artificial intelligence. Researchers began using “cyber” as shorthand for anything involving machines, systems, and information flow.

It was a technical term, but one waiting to jump into popular culture.

---

Enter Cyberspace

The big leap came in 1984 when science fiction author William Gibson published Neuromancer. In it, he described cyberspace as a “consensual hallucination” shared by millions—a digital world inside computer networks.

That vision stuck. By the 1990s, as the internet went mainstream, “cyber” became glued to nearly every online activity: cyber cafés, cybersex, cybercrime, and more. What had once been a mathematical idea now belonged to pop culture.

---

Today’s “Cyber”

Today, “cyber” has narrowed its focus. Governments, businesses, and security professionals use it mostly to describe the digital domain—especially the threats and defenses around it. For example:

• Cybersecurity: protecting systems, networks, and data

• Cyber operations: digital activities carried out by militaries or governments

• Cyber threats: malicious activity in the online space

In other words, “cyber” is shorthand for the intersection of technology, information, and control—exactly where it started back with Wiener.

---

Why It Matters

Words carry history. Understanding where “cyber” comes from helps us see that our conversations about digital safety, control, and communication aren’t entirely new—they’re rooted in centuries-old ideas about guidance, governance, and steering through uncertainty.

So next time you hear “cyber,” remember: it’s not just jargon. It’s a word with a journey—one that began on the decks of Greek ships and found its way into the heart of our digital age.

Ode to Linux

A techie with skills so supreme,
Preferred Linux to Windows' regime.
With sudo and bash,
He solved every crash,
And his uptime was always a dream.

Echoes in the Storm

In the quiet corners of his mind,
A storm swirls, leaving peace behind.
Thoughts race like leaves in a restless breeze,
Yet he's anchored, trapped, on shaking knees.

Loneliness whispers in every sound,
A hollow echo that knows no bound.
The world moves on, but he's out of sync,
Drowning in the chaos where others think.

A spark of hope, a fleeting flame,
Extinguished quickly, the dark's to blame.
Focus shattered, time slips away,
Another lost hour, another gray day.

And yet, within this shadowed strife,
Flickers a will, a thread of life.
Though heavy the burden, deep the despair,
A quiet strength reminds he's still there.

 

BSIT400 - Week 12 Posting - Exploring the Benefits of Infrastructure as Code (IaC)

Infrastructure as Code (IaC) manages IT infrastructure through configuration files, allowing teams to automate and standardize deployments rather than manual processes. In IaC, administrators define infrastructure needs—like servers, networks, and storage—using code, transforming infrastructure management into a process similar to software development (Microsoft, n.d.).

One of IaC’s core benefits is consistency. With every piece of infrastructure described in the code, deployments across environments, such as development, testing, and production, remain consistent. This approach reduces “configuration drift,” which often results from manual changes that complicate troubleshooting and system management over time. When environments match in configuration, applications become more reliable and supportable (Red Hat, n.d.).

IaC also enhances efficiency and speed. With tools like Terraform, Ansible, or AWS CloudFormation, IaC enables quick infrastructure deployment and on-demand scaling. Automated deployments reduce setup time and minimize human error, allowing faster, more reliable updates. This adaptability improves cost efficiency as resources can be scaled up or down according to demand, optimizing infrastructure expenses (HashiCorp, n.d.).

Furthermore, IaC fosters collaboration by allowing infrastructure configurations to be stored and versioned in repositories, similar to software code. Teams can track changes, roll back to previous configurations if needed, and test updates before applying them to production. By treating infrastructure as code, IaC promotes faster iteration, fewer errors, and greater scalability, aligning IT practices with today’s demand for agility (Amazon Web Services [AWS], n.d.).

BSIT400 - Week 11 Posting - Understanding RTO and RPO: Key Metrics for Effective Disaster Recovery Planning

When organizations plan for disaster recovery, two critical metrics guide the process: Recovery Time Objective (RTO) and Recovery Point Objective (RPO). Although often mentioned together, RTO and RPO serve different purposes in helping a business recover from unexpected disruptions. Both metrics help define acceptable downtime and data loss levels, allowing organizations to create a recovery strategy that meets their operational needs and budget.

The Recovery Time Objective (RTO) refers to the maximum time a business can tolerate being offline after a disruption before it starts to experience serious consequences. RTO answers, "How long can we afford to be down?" For example, if a company has an RTO of four hours for its email system, it must restore email access within four hours to avoid significant impacts on business operations. RTO helps businesses prioritize which systems and services need to return to service quickly to minimize financial loss or operational setbacks.

On the other hand, the Recovery Point Objective (RPO) focuses on data loss tolerance. RPO determines how much data a business can lose by setting a time limit for data recovery. For example, if an organization has an RPO of one hour, it means that, in the event of a failure, data recovery should bring the system back to a state no older than one hour before the incident. This requires frequent data backups or replication. Together, RTO and RPO are essential in disaster recovery planning. RTO addresses downtime limits, while RPO manages data loss limits, helping organizations create balanced recovery strategies based on their needs.

BSIT400 - Week 10 Posting - Data Obfuscation 101: Understanding Encryption and Tokenization in Today’s Digital World

In today’s digital world, data breaches are becoming more sophisticated, and protecting sensitive information is more crucial than ever. This is where data obfuscation techniques like encryption and tokenization come into play. These methods serve as essential shields to keep personal, financial, and business-critical data safe from prying eyes.

Encryption is the most well-known method. It converts readable data (plaintext) into a scrambled format (ciphertext) using algorithms and keys. Only someone with the proper key can decrypt and make sense of it. Encryption secures everything from private messages to banking information, whether the data is being stored or transferred. The catch? The safety of encrypted data heavily depends on managing and protecting those keys. If a key falls into the wrong hands, the data becomes vulnerable.

Tokenization, on the other hand, works differently. Instead of scrambling data, it replaces sensitive information with non-sensitive placeholders called tokens. For example, your credit card number could be swapped with a random token that maps back to the actual number in a secure vault. This method is beneficial for payment processing, as even if a hacker gets a hold of the token, it’s worthless without access to the original data.

While both techniques enhance security, they have different strengths. Encryption is versatile but requires diligent key management, while tokenization is ideal for safeguarding specific data elements, like credit card numbers, in compliance-heavy environments. Companies often combine both methods to create robust data protection strategies that balance performance, security, and regulatory needs.

Understanding these techniques is critical to securing our digital world, with cyber threats rising. Whether you’re an IT professional or a concerned internet user, knowing how your data is protected can give you peace of mind in our increasingly connected world.

BSIT400 - Week 9 Posting - Safeguarding Digital Trust: The Crucial Role of Key and Certificate Management

Key and certificate management are critical components of modern cybersecurity. Keys, whether for encryption or signing, and digital certificates, which authenticate identities online, must be managed appropriately to ensure the security and integrity of communications and data in any organization.
Proper key management ensures that encryption keys are stored securely, regularly rotated, and used appropriately to protect sensitive data. If encryption keys are compromised or mismanaged, encrypted data becomes vulnerable to unauthorized access, undermining the entire security system. Managing keys also includes ensuring they are securely shared between parties, preventing them from being intercepted during transmission.

On the other hand, certificate management involves issuing, renewing, and revoking digital certificates that verify the authenticity of websites, applications, and users. Secure communication channels, such as those established using SSL/TLS, can be compromised without well-maintained certificates. Expired or invalid certificates can lead to security warnings or open the door to man-in-the-middle attacks where attackers impersonate legitimate entities.

Both key and certificate management are essential for maintaining the trustworthiness of systems and data exchanges. Without effective management, businesses can face serious risks, including data breaches, loss of customer trust, and non-compliance with security regulations, ultimately threatening their overall security posture.

Whispers at the Door

The night is still, yet something feels amiss,
As children come for treats and playful bliss.
I smile and drop the candy in their bags,
But shadows stretch, and time begins to lag.

Each face I see, a mask, but not quite right,
Their hollow eyes reflect the fading light.
They shuffle close with whispers soft and cold,
My hands grow numb, the candy turns to mold.

They’re not the ones I thought I'd see tonight—
Too late I shut the door against the night.

BSIT400 - Week 8 Posting - Cloud Security Practices

Cloud security is a growing concern, and effective troubleshooting methods are essential for keeping systems safe. One popular methodology is Root Cause Analysis (RCA). This approach involves identifying the underlying cause of an issue to prevent it from happening again. For example, if a cloud server experiences unauthorized access, you must investigate how it occurred and address the vulnerabilities that allowed it. Penetration testing is another valuable strategy. By simulating attacks, organizations can discover weaknesses in their cloud infrastructure before malicious actors do.

The Six-Step Troubleshooting Process is widely used for resolving cloud security issues. This process involves identifying the problem, gathering data, forming a hypothesis, testing the hypothesis, implementing a solution, and monitoring results. This method ensures that all angles are covered when addressing security incidents. Another essential tip is to monitor logs and alerts constantly. Cloud environments provide rich logging data, which can help administrators detect suspicious activity early. Regular audits of user permissions, data encryption methods, and security protocols also play a vital role in maintaining cloud security.

Maintaining cloud security requires a combination of proactive and reactive strategies. Troubleshooting security issues effectively involves thorough investigation, regular testing, and constant vigilance.

BSIT400 - Week 7 Blog Posting - Article Review

For this weeks blog entry, I have decided to provide a review of an interesting article titled "What's the difference between cloud computing and colocation?", written by Alex Carroll and published on the Lifeline Data Centers website at https://lifelinedatacenters.com/colocation/whats-the-difference-between-cloud-computing-and-colocation/. 

The article offers a clear comparison between cloud computing and colocation, two approaches businesses can use for data storage and computing power. Cloud computing provides access to virtualized resources over the internet, making it ideal for companies looking for scalability without investing in physical infrastructure. Conversely, colocation allows businesses to rent space within a data center to house their own servers, providing more control over their hardware but requiring higher upfront investments.

The article makes a strong case for cloud computing's flexibility, especially for startups and smaller businesses that need scalable solutions without the overhead of managing physical servers. By offering virtualized environments, cloud computing reduces the cost of entry and ongoing maintenance. It also simplifies scaling up or down based on the business's needs, a significant advantage in a rapidly evolving market.

In contrast, the article highlights the advantages of colocation for larger companies with more specific requirements. These companies often choose colocation because it allows them to maintain greater control over their hardware and network configurations. Businesses that have invested in physical servers may find colocation a better option, as it helps ensure they meet compliance requirements while keeping their data secure in a professional data center environment.

The article provides valuable insights into how cloud computing and colocation serve different needs. While cloud computing is often favored for its ease of use and scalability, colocation remains a strong option for businesses seeking more control over their physical infrastructure. The choice ultimately depends on each business's specific needs, budget, and long-term goals.
