Sancho VII of Navarre

Sancho VII (Basque: Antso VII.a; c. 1157 – 7 April 1234), called the Strong (Basque: Azkarra, Spanish: el Fuerte), was King of Navarre from 1194 until his death in 1234. He was the son and heir of Sancho VI, whom he followed as the second king to hold the title of King of Navarre. Sancho VII was the first to use the chains of Navarre as his blazon, a symbol that later would become the main one of Navarre, and the last member of the Jiménez dynasty, which had ruled since the 9th century.
