The Control of Border Castles by Templars and Hospitallers (Edexcel A-Level History): Revision Notes
The Control of Border Castles by Templars and Hospitallers
Introduction: the growing reliance on military orders
As the 12th century progressed, the rulers of Outremer faced an increasingly difficult challenge. With limited resources and a growing Muslim threat, they could no longer adequately defend their territories alone. This led to a dramatic shift in defensive strategy, with the Templars and Hospitallers (the two main military orders) taking on responsibility for controlling many of Outremer's most important castles. This arrangement would fundamentally shape the military landscape of the crusader states.
The pressure on these military orders grew substantially over time. Evidence from 1164 shows that 60 Templars were killed defending Artah, but by the Battle of Hattin in 1187, the Templars alone lost approximately 230 brothers trying to prevent Saladin from reaching Jerusalem. These figures demonstrate just how central the military orders had become to Outremer's defensive strategy, and how heavily the survival of the crusader states depended on their military strength.
Why were the military orders given control of castles?
The transfer of castle control to the Templars and Hospitallers was not random, but rather reflected several practical and political considerations that made the military orders uniquely suited to this responsibility.
Superior resources for garrisoning
The military orders possessed the manpower that secular rulers often lacked. When Baldwin IV granted Jacob's Ford to the Templars in 1178, they were expected to maintain a garrison of 80 knights with an additional 900 troops available on call. This was a substantial military commitment that few individual lords could match. The military orders could draw on their extensive networks and resources to maintain these large permanent garrisons, ensuring castles were always adequately defended.
Political trustworthiness
Rulers saw the military orders as politically neutral and reliable. A key example occurred in 1185 when Raymond III of Tripoli became regent for the young Baldwin V. To prevent Raymond from using castle control to permanently seize power in Jerusalem, the castles were placed under the authority of the military orders instead.
This demonstrated that the orders were seen as loyal to the kingdom itself rather than to any particular faction, making them ideal custodians of strategic fortifications during politically uncertain times.
Financial and construction resources
The military orders had the wealth and expertise necessary to build and maintain expensive fortifications. When the Hospitallers received Platta in the 1140s, they were required to fortify it within just one year – a demand that demonstrated confidence in their resources and organisational capability. Building and maintaining castles required significant ongoing investment, which the orders' European estates could provide.
Compensation for weakening government authority
As Muslim pressure increased, secular rulers sometimes transferred castles to the military orders because they feared losing them entirely. In 1157, Baldwin III gave the Hospitallers control of Banyas specifically because he believed it would otherwise be captured by Muslim forces. This pragmatic approach recognised that the military orders had a better chance of holding vulnerable positions than overstretched royal forces.
Settlement of debts
Financial considerations also played a role. Raymond III of Tripoli owed the Hospitallers 80,000 bezants (a substantial sum) for securing his release from a Muslim prison. In 1180, he transferred the fortress of Tuban and surrounding territories to the Hospitallers to settle this debt. This arrangement benefited both parties: Raymond cleared his obligation while the Hospitallers gained valuable strategic assets.
Key strongholds controlled by the military orders
By the 1180s, the extent of castle control by the military orders was remarkable. The Hospitallers held approximately 25 castles, while the Templars controlled around 17. This represented a significant proportion of Outremer's defensive infrastructure, confirming the orders' status as military powers equal to major lords.
Major fortresses and their significance
Some castles were particularly powerful, controlling extensive territories and wielding considerable authority. The Castle of Margat, granted to the Hospitallers by Bernard Le Mazoir in 1186, provides an excellent example. This fortress came with the right to conduct independent negotiations with Muslim invaders without consulting the ruler of Antioch.
This level of autonomy was extraordinary and demonstrated how the military orders' acquisitions elevated them to a status comparable with major territorial lords. The ability to negotiate independently with enemy forces was a privilege normally reserved only for sovereign rulers.
Strategic control of mountain passes
Many castles served the crucial function of controlling access routes into Outremer. Mountain passes were particularly important, as they provided front-line defence against invasion forces and allowed the orders to impose duties on traders. The Castle of Gaston (also known as Baghras), placed under Templar control in the 1130s, exemplifies this strategic role. It commanded the Belen Pass through the Amanus Mountains, which provided access from the north-east into Antioch. By holding this position, the Templars could intercept any invaders from Armenian or Edessan territory, cutting them off in the mountains before they could threaten Antioch itself.
Different types of castles and their purposes
The military orders controlled castles of varying sizes and for different strategic purposes, reflecting the diverse defensive needs of Outremer.
Offensive strongholds
Larger castles served offensive purposes, projecting power into enemy territory. Jacob's Ford, given to the Templars by Baldwin IV with the expectation of an 80-knight garrison, was specifically intended to apply pressure on Damascus and support efforts to capture that city. This represented an aggressive, forward-defence strategy that used castles not just to hold territory but to threaten enemy positions.
Defensive positions
As discussed above, castles controlling mountain passes and other strategic routes provided essential defensive capabilities. These positions allowed the military orders to monitor and control movement into the crusader states, providing early warning of invasions and creating chokepoints where enemy forces could be engaged.
Protection of pilgrims
The military orders also maintained smaller outposts such as Destroit and Yazur, which fulfilled their original mission of protecting Christian pilgrims travelling to holy sites. These installations, while less militarily significant than major fortresses, were essential to ensuring the safety of pilgrims – one of the fundamental purposes for which the military orders were originally established.
The impact of Saladin's incursions in the 1180s
The extensive castle network controlled by the military orders proved vulnerable to determined assault. Saladin's campaigns in the 1180s dramatically transformed the situation. By the decade's end, the military orders had lost control of the majority of their castles.
Remaining strongholds
After Saladin's conquests, only a handful of significant fortresses remained in the orders' hands. The Hospitallers retained Krak des Chevaliers and Margat, while the Templars held Tortosa and Roche Guillaume. Notably, all these surviving castles were located in the northern part of the crusader states.
Consequences for Outremer's defence
This reversal of fortunes demonstrated just how much responsibility the military orders had borne for defending Outremer. The loss of most of their castles created such a desperate military situation that it finally convinced European rulers to launch the Third Crusade. This shows that the castle network maintained by the Templars and Hospitallers had been the backbone of the crusader states' defence strategy – when it collapsed, so too did Outremer's ability to resist Muslim conquest.
Financial support from European nobles
The military orders' ability to maintain extensive castle networks in Outremer depended on sophisticated financial arrangements linking them to western Europe.
Property and estates in Europe
Both the Templars and Hospitallers owned substantial property in western Europe. This property was often donated by sponsors who requested spiritual support, such as prayers after their death, in exchange. Over time, these donations allowed the orders to develop large estates across Europe.
The commandery system
Each estate was managed from a central commandery building. These commanderies were not simply administrative centres but the heart of complex agricultural and economic operations that generated significant revenue. Estate managers worked to maximise income from these properties, ensuring a steady flow of resources to support operations in the crusader states.
The responsion: funding Outremer's defence
Commanderies were required to pay a tax called a responsion, which typically amounted to around one-third of their revenue. This money was sent to support the military orders' operations in Outremer, directly funding the maintenance of castles, payment of troops, and purchase of supplies.
How the Financial System Worked:
European estates generated income through agriculture and rents → Commanderies collected and managed this revenue → One-third was sent as responsion to Outremer → Funds supported castle garrisons, military operations, and fortification construction
This created a reliable financial pipeline connecting European resources directly to the defence of the crusader states.
International financial network
To transfer the responsion from Europe to Outremer, the military orders developed an international network capable of moving messages, money, and materials across vast distances. This was a remarkable organisational achievement for the medieval period and demonstrated the sophisticated infrastructure underpinning the orders' military activities.
Additional financial services
The Templars extended their financial operations even further by offering banking and financial services in western Europe. This diversification helped them raise additional revenue beyond what their estates generated, making them even more capable of supporting Outremer's defence.
Exam tips
For essay questions on the military orders and castles:
- Always explain both the reasons why castles were transferred and the consequences of this transfer
- Use specific examples of castles with their dates and strategic purposes
- Connect castle control to broader themes such as the weakening of royal authority and increasing Muslim pressure
- Compare the roles of the Templars and Hospitallers, noting similarities and differences
- Consider the significance of the loss of castles in the 1180s as evidence of the orders' importance
Common pitfall to avoid:
Don't simply list castles and dates. Instead, explain the strategic significance of each castle and how it fits into the broader defensive strategy of Outremer. Always link specific details to analytical points about change, continuity, and significance.
Remember!
Key Points to Remember:
-
The military orders controlled border castles because they had the resources to garrison and maintain them, were politically trustworthy, and could build fortifications that cash-strapped rulers could not afford.
-
By the 1180s, the Hospitallers controlled approximately 25 castles and the Templars around 17, making them central to Outremer's defensive strategy.
-
Castles served multiple purposes: controlling strategic mountain passes, projecting offensive power (like Jacob's Ford pressuring Damascus), and protecting pilgrims on holy routes.
-
Saladin's incursions in the 1180s devastated the military orders' castle network, with only northern fortresses like Krak des Chevaliers and Margat remaining in Hospitaller hands, demonstrating how dependent Outremer had become on the orders for defence.
-
The orders' European estates, organised through commanderies paying a one-third responsion tax, provided the financial foundation that enabled them to maintain their extensive castle network and military operations in Outremer.
