The First Crusade’s progress was shaped by Islamic political fragmentation and Crusader adaptability. Divisions within the Muslim world and contrasting military tactics were central to events.
Political Divisions in the Islamic World
On the eve of the First Crusade, the Islamic Near East was deeply fragmented. Political instability allowed the Crusaders to advance despite being heavily outnumbered.
Fragmented Power Structures
The once-unified Abbasid Caliphate in Baghdad had lost direct authority, leaving local rulers dominant.
Seljuk Turks controlled large areas, but even within their empire, rival sultans and governors pursued personal ambitions.
The Fatimid Caliphate in Egypt competed with the Seljuks, particularly over the Levant, creating further division.
Local Rulers and Rivalries
Aleppo, Damascus, and Mosul were centres of Seljuk power, but their rulers often resisted co-operation.
Competition between Muslim elites meant no unified response to the Crusaders’ arrival in 1096–97.
The Fatimids sought to reclaim Jerusalem from the Seljuks, sometimes indirectly benefiting Crusader efforts.
Caliphate: A form of Islamic government led by a caliph, considered the successor to the Prophet Muhammad’s political and religious authority.
By 1095 the Seljuk sultanate dominated much of Syria and Mesopotamia, while the Fatimid Caliphate held Egypt and parts of Palestine, including Jerusalem by 1098.

Lack of Unity
No co-ordinated pan-Islamic defence was organised during the First Crusade.
Local Muslim rulers often fought each other, ignoring the external threat.
This disunity contrasts with the later idea of jihad (holy struggle), which became more prominent in response to later Crusades.
Religious Divisions in the Islamic World
Religious division compounded political weakness, reducing the ability to oppose the Crusaders effectively.
Sunni–Shia Divide
Sunni Muslims dominated the Seljuk lands, while Shia Muslims controlled the Fatimid Caliphate in Egypt.
The rivalry between Sunni and Shia powers prevented collaboration.
Instead of uniting against the Crusaders, Sunni and Shia rulers often saw each other as the greater enemy.
Local Sectarianism
Smaller sects and movements, such as the Shi‘ite Ismailis, added complexity to the region’s religious map.
Sectarian mistrust weakened trust between potential allies.
Sunni–Shia Divide: The split within Islam dating back to disputes over rightful leadership after the Prophet Muhammad, dividing the majority Sunni and minority Shia communities.
This enduring divide meant that the Crusaders faced opponents divided both by politics and by faith.
Military Tactics of the Crusaders
The Crusaders were unfamiliar with the terrain of Anatolia and the Levant but adapted their tactics to meet challenges effectively.
Crusader Strengths
Heavy armoured cavalry and disciplined infantry provided decisive battlefield impact.
Use of tight formations helped withstand Turkish horse archers.
Crusaders relied on siege warfare to capture fortified cities.
Key Siege Tactics
Siege towers, rams, and mining operations undermined city walls.
Starvation sieges forced defenders into surrender.
Religious motivation sustained morale through prolonged campaigns.
Military Tactics of the Islamic Opponents
Muslim forces had distinct advantages in mobility and knowledge of the land but struggled against Crusader persistence.
Seljuk Tactics
The horse archer was the hallmark of Seljuk warfare.
Hit-and-run raids disrupted Crusader supply lines.
Guerrilla-style harassment worked best in open terrain.
Fatimid Tactics
Relied more on infantry and fortified strongholds.
Less emphasis on cavalry mobility compared to the Seljuks.
Their defensive strategies delayed but could not prevent Crusader advances.
The Capture of Key Cities
Crusader victories at Edessa, Antioch, and Jerusalem were made possible by exploiting Muslim disunity and adapting effective tactics.
The Capture of Edessa (1098)
The first Crusader state, the County of Edessa, was established when Baldwin of Boulogne gained control.
Local Armenian Christian support was crucial.
Muslim leaders failed to rally against this incursion.
In March 1098 Baldwin of Boulogne seized Edessa, creating the first Crusader state east of the Euphrates.

The Capture of Antioch (1098)
One of the most significant and gruelling sieges of the First Crusade.
Lasted many months, with Crusaders facing famine and desertion.
Betrayal from within the city allowed Crusaders to storm Antioch.
A Muslim relief force arrived too late, suffering defeat due to Crusader determination.
The Capture of Jerusalem (1099)
Jerusalem, held by the Fatimids, became the Crusaders’ ultimate prize.
Crusaders launched a brutal siege, using siege towers and scaling ladders.
After breaking through, Crusaders massacred many inhabitants, shocking the Islamic world.
The Fatimid failure to relieve Jerusalem highlighted ongoing Muslim disunity.
At Jerusalem (1099), timber was ferried inland to build siege towers, allowing the crusaders to bring covered assault bridges onto the northern walls.

This visual clarifies how attackers overcame tall defences when ladders and rams were insufficient. Although generic, it exemplifies the method applied during the First Crusade. Source
Siege Warfare: A military strategy in which an army surrounds and isolates a fortified location, cutting off supplies until surrender or storming becomes possible.
The fall of Jerusalem marked the climax of the First Crusade and symbolised both Crusader tactical persistence and the fractured state of the Islamic world.
FAQ
The Fatimids (Shia) and the Seljuks (Sunni) were locked in both ideological and territorial conflict. The Fatimids wished to reclaim Jerusalem and Syria from Seljuk control, while the Seljuks aimed to expand their dominance further south.
This rivalry meant each side saw the Crusaders as a temporary nuisance rather than the primary threat. Consequently, they prioritised fighting each other over forging a united front.
The Near East was vast and fragmented, with deserts, mountains, and poorly connected cities. This limited the ability of rulers to co-ordinate responses to the Crusaders.
Communication between Aleppo, Damascus, Cairo, and Mosul could take weeks. In contrast, the Crusaders moved in concentrated forces, allowing them to strike divided Muslim territories before relief armies could arrive.
Armenian Christians in Edessa welcomed Baldwin of Boulogne’s arrival in 1098.
Many locals saw the Crusaders as liberators from Muslim rule, particularly from harsh Seljuk governors.
They provided supplies, intelligence, and legitimacy to Baldwin’s claim.
Their co-operation reduced resistance and allowed a Crusader foothold to develop into the first Crusader state.
At Antioch, Muslim defenders relied on the city’s massive fortifications and hoped for outside relief armies to break the siege.
At Jerusalem, the Fatimids placed greater emphasis on maintaining walls and defences but lacked a timely relief effort. The Crusaders exploited this by bringing timber for siege towers, something that proved decisive.
Most major objectives—Edessa, Antioch, Jerusalem—were heavily fortified cities. Unlike open-field battles, control of these centres required prolonged sieges.
Sieges allowed Crusaders to capture key supply bases and strongholds.
Fortified towns controlled trade routes and communication lines, crucial for sustaining Crusader states.
Victory in sieges had symbolic as well as strategic importance, particularly at Jerusalem, the spiritual goal of the campaign.
