The Lapua Movement was a radical Finnish nationalist, fascist, pro-German and anti-communist political movement founded in and named after the town of Lapua. Led by Vihtori Kosola, it turned towards far-right politics after its founding and was banned after a failed coup d'etat attempt in 1932. The movement's anti-communist activities continued in the parliamentarian Patriotic People's Movement.
