The First Crusade (1095–1099): The Complete History of the Crusade That Captured Jerusalem

Introduction: What Was the First Crusade?

The First Crusade (1095–1099) was one of the most significant military and religious campaigns of the medieval world. Initiated by Pope Urban II at the Council of Clermont in 1095, the crusade aimed to assist the Byzantine Empire against the Seljuk Turks and reclaim Jerusalem and other holy sites from Muslim control. (Encyclopedia Britannica)

What began as a papal call to arms evolved into a massive international movement involving knights, nobles, peasants, and clergy from across Europe. By 1099, crusader armies captured Jerusalem and established several Crusader States in the Middle East.

The First Crusade is often considered the only major crusade to achieve its primary objective. Yet its legacy remains deeply controversial because of its violence, religious zeal, massacres, and long-term effects on Christian-Muslim relations.

The Causes of the First Crusade

Understanding the causes of the First Crusade requires examining the political, religious, and military conditions of the late 11th century.

1. The Byzantine Empire Requested Help

The Byzantine Emperor Alexios I Komnenos faced severe pressure from the Seljuk Turks, who had conquered much of Asia Minor after the Battle of Manzikert in 1071. Seeking military assistance, Alexios appealed to the papacy. (Wikipedia)

Pope Urban II recognized an opportunity to:

• Strengthen papal influence

• Aid Eastern Christians

• Potentially reunite the Eastern and Western Churches

2. Religious Motivation

Religion was central to the crusading movement. Christians viewed Jerusalem as the holiest city in Christianity because of its association with the life and death of Jesus Christ.

Urban II framed the expedition as both:

• A pilgrimage

• A holy war

Participants were promised remission of sins if they joined the campaign. (School History)

3. European Warfare and Social Pressure

Western Europe in the 11th century was marked by frequent noble conflicts and violence. Urban II sought to redirect this aggression outward.

According to several chroniclers, the pope encouraged knights to stop fighting fellow Christians and instead fight in the East. (Internet History Sourcebooks)

The Council of Clermont (1095)

The defining moment of the First Crusade occurred at the Council of Clermont in November 1095. (Encyclopedia Britannica)

There, Pope Urban II delivered one of the most famous speeches in medieval history.

Primary Source: Fulcher of Chartres

One of the best-known versions of Urban’s speech comes from Fulcher of Chartres, a priest who later joined the crusade.

Urban reportedly declared:

“Christ commands it.” (Internet History Sourcebooks)

The crowd allegedly responded with the famous cry:

“Deus vult!” (“God wills it!”) (School History)

Although historians debate the exact wording of the speech, there is no doubt that Clermont sparked enormous enthusiasm throughout Europe.

The People’s Crusade

Before the main armies departed, an unofficial movement known as the People’s Crusade emerged under the preacher Peter the Hermit.

Thousands of poorly equipped peasants and commoners marched east in 1096. The expedition descended into chaos and included massacres of Jewish communities in parts of Europe. (Ron Cantor)

Most of these crusaders were destroyed by Turkish forces at the Battle of Civetot in 1096. (HistoryExtra)

The failure demonstrated the need for disciplined military leadership.

The Main Crusader Armies

The official crusading armies departed later in 1096 under several major leaders, including:

• Godfrey of Bouillon

• Raymond IV of Toulouse

• Bohemond of Taranto

• Tancred

Unlike modern unified armies, these forces operated independently and often disagreed with one another.

Still, they shared the common objective of reaching Jerusalem.

The Siege of Nicaea (1097)

The crusaders achieved their first major victory at Nicaea, a Seljuk stronghold in Asia Minor.

With assistance from Byzantine forces, the city surrendered in June 1097. (Wikipedia)

This success strengthened crusader morale and demonstrated the importance of Byzantine naval and logistical support.

The Battle of Dorylaeum

Soon after leaving Nicaea, the crusaders faced a major Turkish attack at the Battle of Dorylaeum.

Despite initial difficulties, the crusaders prevailed through heavily armored cavalry charges and reinforcements. The victory allowed the expedition to continue deeper into Anatolia.

The Siege of Antioch (1097–1098)

The Siege of Antioch became one of the hardest and most brutal phases of the First Crusade.

Why Antioch Was Important

Antioch controlled a strategic route into Syria and Palestine. Capturing it was essential before advancing toward Jerusalem.

The siege lasted from October 1097 until June 1098 and caused:

• Starvation

• Disease

• Desertion

• Severe morale problems

(De Re Militari)

Primary Source: The Gesta Francorum

An anonymous crusader author recorded the suffering during Antioch in the Gesta Francorum, one of the most important eyewitness chronicles of the crusade.

The text describes famine and desperation among crusaders trapped between enemy forces and starvation. (Alex Anderson)

Eventually, crusaders captured Antioch through the betrayal of a guard who allowed them entry into the city.

However, shortly afterward, crusaders themselves were besieged inside Antioch by Muslim relief forces.

The Holy Lance Controversy

During the Antioch crisis, a monk named Peter Bartholomew claimed to discover the Holy Lance, believed to be the spear that pierced Christ during the crucifixion.

The relic boosted crusader morale dramatically, although many leaders doubted its authenticity.

Nevertheless, inspired crusaders defeated the Muslim army outside Antioch in 1098.

The March to Jerusalem

By early 1099, the crusaders marched south toward Jerusalem.

The journey was difficult because:

• Many crusaders had died

• Supplies were limited

• Internal rivalries persisted

Still, the surviving crusaders remained determined to capture the Holy City.

The Siege of Jerusalem (1099)

The Siege of Jerusalem was the climax of the First Crusade.

Crusader forces reached Jerusalem in June 1099 and began a five-week siege against the Fatimid defenders. (Wikipedia)

Challenges Facing the Crusaders

• Lack of water

• Extreme summer heat

• Shortage of siege materials

• Strong city defenses

To overcome these obstacles, crusaders constructed siege towers and scaling ladders.

The Capture of Jerusalem

On July 15, 1099, crusader forces breached Jerusalem’s defenses and captured the city. (Wikipedia)

The aftermath became infamous for widespread massacres of Muslim and Jewish inhabitants.

Primary Source: Raymond of Aguilers

One crusader chronicler described scenes of extreme violence after the conquest.

Modern historians debate casualty numbers, but contemporary accounts agree that the capture involved large-scale killing. (Wikipedia)

The Establishment of the Crusader States

After Jerusalem fell, crusaders established several states in the eastern Mediterranean, including:

• The Kingdom of Jerusalem

• The County of Edessa

• The Principality of Antioch

• The County of Tripoli

These states became the political foundation for later crusading activity.
