Miquel Badia i Capell (1906–1936) was a prominent figure of radical Catalan separatism during the days of the Second Spanish Republic, member of Estat Català and the JERC, Chief of Public Order of the Generalitat of Catalonia.

[3] After the proclamation of the Second Spanish Republic in April 1931, Badia, an ardent follower of Francesc Macià,[4] became allied to Josep Dencàs; both got to control the JERC,[5]—youth wing of the newly created Republican Left of Catalonia (ERC)—and its shock squads, the olive green-shirted escamots.

Described by Payne as proto-fascists,[6] both Badia and Dencàs talked about the prospect of paving the way for the establishment of ERC as single party of a future Catalan state drawn under a "national" and "socialist" corporative order.

A participant of the armed insurrection against the republican government produced in Catalonia after the entry of three CEDA ministers in the new cabinet presided by Alejandro Lerroux (Events of 6 October), he escaped afterwards and crossed the French-Spain border, settling in Paris.

[13] After the win of the Popular Front in the 1936 Spanish general election, he returned to Catalonia already in February 1936 expecting the issuance of an amnesty due to the success of the left-wing coalition,[14] as it finally was the case.
