It was proclaimed on 14 April 1931, and superseded three days later, on 17 April, by the Generalitat de Catalunya, the Catalan institution of self-government within the Spanish Republic.

Francesc Macià i Llussà was a Catalan politician who served as the 122nd president of the Generalitat of Catalonia, and formerly an officer in the Spanish Army.
