集中と統一
Parties that consider themselves either Catalan nationalist or independentist have been present in all Catalan governments since 1980. The largest Catalan nationalist party, Convergence and Union, ruled Catalonia from 1980 to 2003, and returned to power in the 2010 election. Between 2003 and 2010, a leftist coalition, composed by the Catalan Socialists' Party, the pro-independence Republican Left of Catalonia and the leftist-environmentalist Initiative for Catalonia-Greens, implemented policies that widened Catalan autonomy.
