EH Bildu, short for Euskal Herria Bildu (English: 'Basque Country Gather' or 'Basque Country Unite'), is a left-wing, Basque nationalist and pro-independence federation of political parties in Spain. It is the main political force of the abertzale left in Spain. EH Bildu is active in the Spanish Basque Country, that is, in the Basque Autonomous Community and Chartered Community of Navarre, as well as in the Treviño enclave of the Burgos Province. In the French Basque Country, it has an alliance with the party Euskal Herria Bai, with the goal of establishing a state for the Basque Country across the Spanish-French border.
