It lasted only from 21 March until 1 August 1919. The state was led by Béla Kun and was not recognized by France, the UK or the US. It was the second socialist state in the world to be formed after the October Revolution in Russia brought the Bolsheviks to power. The Hungarian Republic of Councils had military conflicts with the Kingdom of Romania (see Hungarian–Romanian War), the Kingdom of Serbs, Croats and Slovenes and the evolving Czechoslovakia. It collapsed on 1 August 1919 when Hungarians sent representatives to negotiate their surrender to the Romanian forces and Béla Kun, together with other high-ranking Communists, fled to Austria.
