House of Haro

The House of Haro was the most powerful family of Castile during the Middle Age and strongly supported the expansionist policies of Alfonso VI of Castile. As a reward, Íñigo López was named the first Lord of Biscay.

In the early 1500s, the Haro family married paternally into the House of Sotomayor establishing a branch that would go on to hold dominion over the Marquesado del Carpio established in 1559 by King Phillip II of Spain.
