Solidaridad Internacional Antifascista

Solidaridad Internacional Antifascista (English: International Antifascist Solidarity), SIA, was a humanitarian organisation that existed in the Second Spanish Republic.

[2] It collaborated with the Mujeres Libres organisation to provide assistance to refugees and wounded soldiers.

[3] The decision to create the SIA was made in Valencia on 15 April 1937, but it did not effectively begin until June of that year, after the May Days in Barcelona pit anarchists and anti-Stalinist communists against the Spanish Republic, the Executive Council of Catalonia, and statist communists.

It served to spread anarchist ideas during the Spanish Civil War and allowed the CNT to gain material support from abroad.

The association organized the defence of asylum seekers and was a meeting place for immigrants, including Spanish CNT members in exile.
