Catalonia's autonomous government, led by Lluís Companys (pictured), declared a general strike, an armed insurgency, and the establishment of the Catalan State in reaction to the inclusion of conservatives in the Spanish republican regime.

Catalonia is an autonomous community of Spain, designated as a nationality by its Statute of Autonomy. Most of its territory is situated on the northeast of the Iberian Peninsula, to the south of the Pyrenees mountain range. Catalonia is administratively divided into four provinces or eight vegueries (regions), which are in turn divided into 43 comarques. The capital and largest city, Barcelona, is the second-most populous municipality in Spain and the fifth-most populous urban area in the European Union.

Lluís Companys i Jover was a Catalan politician who served as president of Catalonia from 1934 and during the Spanish Civil War.

The events of 6 October were a general strike, armed insurgency and declaration of a Catalan State in Catalonia during the Revolution of 1934 on 6 October 1934.

The Catalan State was a short-lived state that existed in Catalonia from 6 to 7 October 1934 during the Events of 6 October. The Catalan State was proclaimed by Lluís Companys, the left-wing President of the Generalitat of Catalonia, as a state "within the Spanish Federal Republic" in response to members of the right-wing CEDA party being included in the government of Second Spanish Republic. The Catalan State was immediately suppressed by the Spanish Army led by General Domènec Batet and Companys surrendered the next day.

The Spanish Republic, commonly known as the Second Spanish Republic, was the form of democratic government in Spain from 1931 to 1939. The Republic was proclaimed on 14 April 1931 after the deposition of King Alfonso XIII. It was dissolved on 1 April 1939 after surrendering in the Spanish Civil War to the Nationalists led by General Francisco Franco.
