William the Lion, sometimes styled William I and also known by the nickname Garbh, "the Rough" ( 1142 – 4 December 1214), reigned as King of Scots from 1165 to 1214. His 48-year-long reign was the second longest in Scottish history, and the longest for a Scottish monarch before the Union of the Crowns in 1603. Early life William was born around 1142, during the reign of his grandfather King David I of Scotland. His parents were the king's son Henry and Ada de Warenne. William was around 10 years old when his father died in 1152, making his elder brother Malcolm the heir apparent to their grandfather. From his father, William inherited the Earldom of Northumbria. David I died the next year, and William became heir presumptive to the new king, Malcolm IV. In 1157, William lost the Earldom of Northumbria to Henry II of England. Reign Malcolm IV did not live for long, and upon his death on 9 December 1165 at age 24, William ascended the throne. The new monarch was crowned on 24 December 1165. In contrast to his deeply religious, frail brother, William was powerfully built, redheaded, and headstrong. He was an effective monarch whose reign was marred by his ill-fated attempts to regain control of his paternal inheritance of Northumbria from the Anglo-Normans.

William was then a key player in the Revolt of 1173–74 against Henry II, which was led by Henry's sons with some short-lived assistance from Louis VII. In 1174, at the Battle of Alnwick, during a raid in support of the revolt, William recklessly charged the English troops himself, shouting, "Now we shall see which of us are good knights!" He was unhorsed and captured by Henry's troops led by Ranulf de Glanvill and taken in chains to Newcastle, then Northampton, and then transferred to Falaise in Normandy. Henry then sent an army to Scotland and occupied it. As ransom and to regain his kingdom, William had to acknowledge Henry as his feudal superior and agree to pay for the cost of the English army's occupation of Scotland by taxing the Scots. The cost was equal to 40,000 Scottish marks (£). The church of Scotland was also
