The Central Committee of Antifascist Militias of Catalonia (Catalan: Comitè Central de Milícies Antifeixistes de Catalunya, CCMA) was an administrative body created on 21 July 1936 by the president of the Government of Catalonia, Lluís Companys, under pressure by the anarcho-syndicalists of the National Confederation of Labor (CNT) and Iberian Anarchist Federation (FAI), which led the workers' struggle against the July 1936 military uprising in Barcelona.

The 18 July coup failed to gain control of Catalonia, due to the victory of republican forces on the one hand and the workers' revolt led by the CNT-FAI on the other.

These events turned the distribution of power in Catalonia upside down: the anarchists, until recently relegated to the underground, emerged as the main force after defeating and taking control of strategic positions in the city, such as the artillery barracks of L'Harmonia.

From the first days the Generalitat of Catalonia was totally overwhelmed by the mass actions in the streets, through popular committees that organized life in the neighborhoods of Barcelona.

In this situation of lack of legitimacy of the republican state, a joint body was established by the different Catalan anti-fascist political parties and trade unions (which at that time dominated the streets).

Today you are the owners of the city and Catalonia, because only you have defeated the fascist military, and I hope that it will not hurt you that at this moment I remind you that you have not lacked the help of the few or many loyal men of my party and the guards and mossos ...

If, on the contrary, you believe in this position, that only in death I would have left it to the triumphant fascists, I can, with the men of my party, my name and my prestige, be useful in this fight, which although it ends today along with my prestige in the city, we do not know when and how it will end in the rest of Spain, you can count on me and my loyalty as a man and as a politician who is convinced that today a whole embarrassing past is dying, and who sincerely wishes that Catalonia leads the way of the most advanced countries in social matters.

The Committee had a clear predominance of anarchist organizations, although it included all the forces of the Popular Front (ERC, POUM, PSUC, Republican Union, Unió de Rabassaires and UGT).

With the application of the non-intervention treaty on 8 August, 1936, it became impossible to legally purchase war material from the European democracies, the committee was forced to buy weapons illegally from traffickers and pass -they across the French border.

[8][9] The Majorca operation was organized by the Generalitat (dominated by ERC) in collusion with the PSUC and in which the Barcelona Transport Union of the CNT also participated, on the initiative of the commander Alberto Bayo.

Finally, on 1 October 1936 the CCMA dissolved itself,[11] among other reasons, due to a certain stabilization of the situation at the institutional level and the need to reinforce the governing role of the Generalitat.
