Military service (AQA GCSE History): Revision Notes
Military service
William's need for control
When William became king in 1067, he faced an enormous challenge. He was now responsible for governing approximately two million people, most of whom were hostile to Norman rule. To maintain control over his new kingdom, William desperately needed a reliable supply of soldiers. The feudal system became his solution, providing him with the military force necessary to keep England under Norman control.
The scale of William's challenge cannot be overstated - ruling a hostile population of two million people with only a small Norman elite required an entirely new approach to military organisation.
This military system was fundamentally different from what had existed before. William couldn't simply rely on voluntary support or temporary arrangements - he needed a structured, dependable way to ensure he always had access to fighting men when threats arose.
The feudal exchange: land for military service
The heart of Norman military service lay in a simple but binding exchange. When William granted land to his tenants-in-chief (the most important nobles), they didn't receive it as a gift. Instead, they entered into a formal agreement where they promised complete loyalty to the king and committed to providing a specific number of knights when required.
This arrangement was legally binding and carried serious consequences if broken. The tenant-in-chief had to deliver exactly what they had promised - there was no room for negotiation or excuses.
Some of these powerful nobles chose to pay for professional soldiers (troops), while others preferred to grant portions of their land to individual knights, who would then owe military service in return.
These knights served multiple purposes in William's military strategy. They formed the backbone of castle garrisons, living within the fortifications and ready to defend them at a moment's notice. They also served as the king's mobile strike force, ready to march out and suppress rebellions wherever they might occur. Additionally, the king maintained his own household knights, who acted as his personal bodyguard and formed the elite core of his army, similar to how the Anglo-Saxon kings had used their houscarls.
Changes from the Anglo-Saxon system
While Norman knights might seem similar to Anglo-Saxon thegns, there were crucial differences that made the Norman system much more effective for William's purposes.
The most significant change was the introduction of formal, structured military obligations. Under the Anglo-Saxon system, thegns would be called upon when needed, but there was no guaranteed minimum service period. Norman knights, however, were required to serve for at least 40 days each year - a specific, measurable commitment that William could rely upon when planning military campaigns.
Perhaps even more importantly, military service became viewed as a religious duty under Norman rule. Knights swore sacred oaths to provide service to their lords, making military service not just a political obligation but a spiritual one. This religious dimension made it much harder for knights to avoid their duties or break their commitments.
The scale of this system was impressive. By the end of the 12th century, approximately 5,000 knights throughout England owed military service, creating a substantial and reliable military force that could be mobilised when needed.
Defending the Welsh border
Wales presented a unique military challenge for William. Unlike England, Wales wasn't a unified kingdom in the 11th century. Instead, it was divided among five separate warrior princes, each controlling their own territory and frequently engaging in warfare with their neighbours. This fragmentation meant William couldn't conquer Wales through a single decisive campaign, as he had done with England.
The fragmented nature of Wales - with five separate warrior princes constantly fighting each other - meant that traditional conquest tactics wouldn't work. William needed a completely different approach for this challenging border region.
The border region between England and Wales (known as the Marches) came under constant attack from Welsh raiders. William recognised that he couldn't personally manage this ongoing threat while also governing the rest of England. His solution was both practical and innovative.
William chose to grant unusually large territories to his most trusted followers in the border regions - the Earls of Chester, Shrewsbury, and Hereford. These men became known as the Marcher Lords, and they received extraordinary powers that other Norman nobles didn't possess. They could maintain their own private armies without requiring royal permission, construct castles wherever they saw fit without royal approval, and create laws for their territories.
In exchange for these exceptional privileges, the Marcher Lords took on the responsibility of defending their regions against Welsh attacks. They didn't just sit behind their castle walls waiting - they actively launched attacks into Welsh territory, gradually claiming land and extending Norman influence. While they never achieved complete control over Wales, their aggressive approach succeeded in protecting English territory from Welsh raids.
Managing the Scottish threat
Scotland presented a different type of challenge. In 1072, William decided to take direct military action against the Scots, personally leading an invasion force northward. However, this campaign proved unsuccessful, demonstrating that military force alone wouldn't solve the Scottish problem.
Learning from this setback, William adopted a two-pronged strategy. He appointed the Prince-Bishop of Durham, giving this religious leader similar powers to the Marcher Lords in Wales. The Prince-Bishop could maintain military forces and defend the northern border against Scottish incursions.
More significantly, William pursued a diplomatic solution. The Treaty of Abernethy, signed in 1072, represented a major political achievement. Under this agreement, King Malcolm III of Scotland became a client king of the Normans, theoretically acknowledging William's superior authority.
While this arrangement looked successful on paper, it didn't end the practical problems. Scottish raids across the border continued to occur, showing that formal agreements didn't always translate into peaceful relations.
Timeline of key events

- 1072: William's unsuccessful invasion of Scotland
- 1072: Treaty of Abernethy signed, making Malcolm III a client king
- Late 11th/early 12th century: Marcher Lords system fully established on Welsh border

Key Points to Remember:
-
Military service became formalized - Norman knights owed at least 40 days of service per year, unlike the informal Anglo-Saxon system
-
Land came with obligations - Tenants-in-chief received land in exchange for providing specific numbers of knights, creating a binding feudal contract
-
Border defence required special solutions - Marcher Lords in Wales and the Prince-Bishop of Durham received exceptional powers to defend against raids
-
Religious duty strengthened loyalty - Military service became a sacred oath, making it harder for knights to avoid their obligations
-
Scale was impressive - By the late 12th century, around 5,000 knights owed military service throughout England
