The Republican Nationalist Federal Union (Spanish; Castilian: Unión Federal Nacionalista Republicana, Catalan; Valencian: Unió Federal Nacionalista Republicana. UFNR; 1910–1917) was a left-republican political party in Catalonia, Spain.[1]
In 1914, UFNR signed a deal with the Radical Party, the "Pact of San Gervasio", seeking to challenge the political hegemony of Regionalist League in Barcelona. The alliance was, however, unsuccessful.[2]
