UDALBILTZA is the Basque Assembly of Town Halls and Municipal Representatives. It was created on September 18, 1999, at the Euskalduna Palace in Bilbo, by almost two thousand municipal representatives from the seven Basque provinces. Their aim was to counter the process of national de-structuring caused by the lack of national institutions over the centuries. UDALBILTZA is a single institution, despite its various lines of work. All municipal representatives elected throughout the 684 cities, towns and villages in the Basque Country have the right to take part in UDALBILTZA, regardless of religion, gender or ideology.

The aims of UDALBILTZA

- Right from its foundational assembly, UDALBILTZA has had two main aims: firstly, to assert the existence of the Basque Country as a nation unto itself, both at a national and international level, despite the denial of the Basque Country as a subject of rights by the Spanish and French states; secondly, to promote Nation Building.

- Being a national institution made up of town halls and municipal representatives, UDALBILTZA is based on the support of town halls and municipal representatives freely and democratically expressed; it promotes joint work by town halls and municipal representatives, over and above the legal, political and administrative divisions imposed upon the Basque Country.
