The Portuguese Maximalist Federation (Portuguese: Federação Maximalista Portuguesa or FMP) was a revolutionary movement founded in 1918 in Portugal. It was inspired by the most radical factions involved in the Russian revolution of 1917.
This organization, mostly composed by anarcho-syndicalists and revolutionary socialists led to the foundation of the Portuguese Communist Party.
The FMP started publishing the weekly Bandeira Vermelha (Red Flag), which quickly became a very popular newspaper among the Portuguese working classes.
