All these parties usually ran by themselves competing with each other at elections held in the neighbouring autonomous community of the Basque country but agreed to run together in Navarre.

The coalition came up third and won a seat in the Spanish Parliament in 2004, gaining 18.4% of the votes cast in Navarre.

In 2007 the coalition became the second largest political force in Navarre's autonomous parliament, virtually tied with the Spanish Socialist Workers' Party (PSN–PSOE) by obtaining 23.7% of the votes cast and 12 seats.

Its most significant politicians were Patxi Zabaleta (Aralar), Maiorga Ramírez (Eusko Alkartasuna) and Uxue Barkos, a respected journalist who had worked for the Basque Television.

By 2011, new parties and coalitions jumped onto the political scene on the eve of the votation campaign after tribunals in Madrid decided on their legalization.
