Editing POUM (section)

==Formation==
In 1935, POUM was formed as a communist opposition to the [[Stalinism|Stalinist]] form of [[communism]] promoted by the [[Soviet Union]], by the revolutionaries [[Andreu Nin]] and [[Joaquín Maurín]]. Nin was profoundly influenced by the thinking of [[Leon Trotsky]], particularly his [[permanent revolution]] thesis. It resulted from the merging of the Communist Party's [[Left Opposition]] (the [[Trotskyism|Trotskyist]] [[Communist Left of Spain]]) and the [[Right Opposition]] (the [[Workers and Peasants' Bloc]]). This alliance was against the wishes of Trotsky, with whom the Communist Left of Spain broke. [[The Spanish Revolution, 1931–1939 (Trotsky book)|In his writings on the Spanish Revolution]], Trotsky would elaborate on his criticisms of the POUM such as their abandonment of the [[Left Opposition]] program in favour of reformism to retain tactical advantage among other political tendencies.<ref name="Pathfinder Press">{{cite book |last1=Trotsky |first1=Leon |title=The Spanish Revolution, 1931−1939 |date=1973 |publisher=Pathfinder Press |isbn=978-0-87348-273-8 |pages=17–52 |url=https://books.google.com/books?id=BocizgEACAAJ |language=en}}</ref>
