Sancho VI Garcés (c.1133 - June 27, 1194), called the Wise (el Sabio), was the king of Navarre from 1150 until his death in 1194.
Son of King García VI Ramírez and Marguerite de l'Aigle, he was the first to use the title "King of Navarre" as the sole designation of his kingdom, dropping Pamplona out of titular use.
His reign was full of clashes with Castile and Aragón. He was a monastic founder and many architectural accomplishments date to his reign. He is also responsible for bringing his kingdom into the political orbit of Europe.
He tried to repair his kingdom's borders which had been reduced by the Treaties of Tudellén and Carrión, which he had been forced to sign with Castile and Aragón in his early reign. By the Accord of Soria, Castile was eventually confirmed in its possession of conquered territories. He was hostile to Raymond Berengar IV of Aragón, but Raymond's son Alfonso II divided the lands taken from Murcia with him by treaty in 1163. In 1190, the two neighbours again signed a pact in Borja of mutual protection against Castilian expansion.
He died on June 27, 1194, in Pamplona, where he is interred.
He married Sancha of Castile in 1157, the daughter of Alfonso VII. Their children were:
* Sancho VII of Navarre
* Ramiro, Bishop of Pamplona
* Berengaria of Navarre (died 1230 or 1232), married Richard I of England
* Blanca of Navarre, married Count Theobald III of Champagne, then acted as regent of Champagne, and finally as regent of Navarre
Sancho married Sancha Alfonsa Princess of Castile, daughter of King Alfonso VII "Pierre-Raimund" of Castile and Léon and Galicia and Berenguela Raimundo de Barcelona, in 1153. (Sancha Alfonsa Princess of Castile was born about 1138 in Toledo, Toledo, Castile and died on 12 Aug 1177.)
