David I of Scotland

David I introduced Norman-style feudalism to Scotland, granting lands to Anglo-Norman knights in exchange for military service. He established a system of sheriffdoms and castles, transforming Scottish governance and land tenure. This laid the foundation for a centralized medieval kingdom.

David I founded several monasteries, including Melrose Abbey (Cistercian) and Holyrood Abbey (Augustinian). He also supported the establishment of other religious houses, bringing continental monastic orders to Scotland. These foundations promoted religious reform and economic development.

David I created the first royal burghs in Scotland, including Berwick, Roxburgh, and Edinburgh. These towns were granted trading privileges and self-government, stimulating commerce and urban growth. The burgh system became a key feature of Scottish economic life.

David I invaded northern England during the civil war between Stephen and Matilda. He was defeated at the Battle of the Standard near Northallerton in August 1138. Despite the defeat, he negotiated the Treaty of Durham, which secured control of Cumberland and Northumberland for Scotland.

After the Battle of the Standard, David I negotiated the Treaty of Durham with King Stephen. The treaty granted David control of the earldoms of Cumberland and Northumberland, significantly expanding Scottish territory. This was a diplomatic success despite the military defeat.
