Artur Mas i Gavarró (Catalan pronunciation: ; born 31 January 1956) is a Spanish politician, Catalan nationalist. He was President of the Government of Catalonia from 2010 to 2015 and acting president from September 2015 to 12 January 2016.
Mas is a long time member of Democratic Convergence of Catalonia (CDC by its Catalan acronym) which used to be the bigger of the two component members –along with Unió Democràtica de Catalunya– of what at the time was a long-standing electoral coalition, Convergència i Unió (CiU), a liberal nationalist coalition which had dominated Catalan regional politics since the 1980s. In 2001 Mas was named general secretary of CDC, then, in 2012 he was named president of the party until the party was refounded in July 2016 as PDeCAT, which he presided between July 2016 and January 2018.
From 2003 to 2015 Mas has run five times for the Catalan presidency, four heading the –nowadays defunct– CiU ticket and one running for the novel Junts pel Sí coalition. He attained the presidency in two elections, 2010 and 2012 (both running for CiU) but neither with an absolute majority. In the absence of single party majorities, both tenures were marked by political instability and ended with Mas calling a snap election.
