Sancho VI of Navarre

Sancho VI, called the Wise (1132–1194), succeeded his father García Ramírez in 1150, the first to style himself King of Navarre rather than of Pamplona. He inherited a weakened kingdom: Castile had agreed to partition it in the 1140 Treaty of Carrión.

In 1168 he and Alfonso II of Aragon partitioned Murcia at Sangüesa, and in 1181 he founded San Sebastián, Vitoria and Treviño on his western frontier to strengthen royal authority against Castilian expansion.

His daughter Berengaria married Richard I of England in 1191. He died in Pamplona on 27 June 1194 and was succeeded by Sancho VII.
