Overview
Ranulf de Glanvill (alias Glanvil, Glanville, Granville, etc., died 1190) was Chief Justiciar of England during the reign of King Henry II (1154–89) and was the probable author of Tractatus de legibus et consuetudinibus regni Anglie (The Treatise on the Laws and Customs of the Kingdom of England), the earliest treatise on the laws of England.
Political and legal career
There are no primary sources citing when or where he was born. He is first heard of as Sheriff of Yorkshire, Warwickshire and Leicestershire from 1163 to 1170 when, along with the majority of High Sheriffs, he was removed from office for corruption.
However, in 1173, he was appointed Sheriff of Lancashire and custodian of the honour of Richmond. In 1174, when he was Sheriff of Westmorland, he was one of the English leaders at the Battle of Alnwick, and it was to him that the king of Scotland, William the Lion, surrendered.
In 1175, he was reappointed Sheriff of Yorkshire, in 1176 he became justice of the king's court and a justice itinerant in the northern circuit, and in 1180 Chief Justiciar of England. It was with his assistance that Henry II completed his famous judicial reforms, though many had been carried out before he came into office. He became the king's right-hand man, and during Henry's frequent absences was in effect regent of England. In 1176, he was also made custodian of Queen Eleanor, who was confined to her quarters in Winchester Castle.
