Sancho III (The Great) of Navarre (c. 985-October 18 1035) was born to Garcia II of Navarre. He ascended the throne in 1004. Having gone further than any previous Christian monarch in uniting the principalities of Spain, his work was undone when he divided his domains at his death. At its height his rule extended from the borders of Galicia in the west to the county of Barcelona in the east.
