Catalan leader and founder of the nationalist party Estat Català (1922), who played a major role in achieving an autonomous status for Catalonia.

Maciá was a career military officer who became involved in Catalan politics in 1906. In the turmoil after the collapse of Miguel Primo de Rivera (Primo de Rivera, Miguel)'s dictatorship, Macià formed the Republican Left of Catalonia, a coalition of the Catalan Republican Party, the Estat Català, and a third party. After the electoral victory over the Spanish monarchy (April 1931), Macià proclaimed the Catalan Republic, although under pressure from Republicans and socialists he quickly withdrew it in return for a promise that the Republican government would grant home rule. One year later (September 9, 1932) the statute of Catalonian autonomy was promulgated.

As head of the Catalan government, Macià faced leftist discontent. In the resulting swing to the right, Macià's Republican Left was defeated in the election of November 19, 1933. He died five weeks later.
