Republican Antifascist Military Union
anti-fascist organization during the Second Spanish Republic

The Republican Antifascist Military Union (Spanish: Unión Militar Republicana Antifascista; UMRA) was a self-described anti-fascist organization for members of the Spanish Republican Armed Forces in Spain during the period of the Second Spanish Republic.
By 1935, the Spanish Military Union, a secret military organization of pro-fascist officers of the Spanish Republican Armed Forces had extended its influence among Spanish officers and began displaying open hostility towards the Spanish Republic. In order to oppose and neutralize this movement, Eugenio Rodríguez Sierra, an officer of the Spanish Republican Navy was instrumental in the foundation of the Antifascist Military Union. The Unión Militar Antifascista was later merged with the Republican Military Union, another group of similar goals that had been founded in 1929 within the Army, in order to create the Republican Antifascist Military Union.
One of the members of UMRA, Captain Carlos Faraudo, would be blacklisted by Spanish Military Union. He had allegedly been placed at the top of the list before being murdered. Membership of this secret society was especially high among the Assault Guard. One of its leading members, Captain Díaz Tendero, was later to perish at the Mauthausen–Gusen concentration camp.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Republican Antifascist Military Union”, the useful work is to connect “anti-fascist organization during the Second Spanish Republic” to the records capable of establishing context and consequence.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Aug 14, 2025. The linked authority identifier is Q3327179. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1935, 1929 and 2006.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
