Ivan Šubašić in the context of "Tito–Šubašić Agreements"

Democratic Federal Yugoslavia, also known as Democratic Federative Yugoslavia (DF Yugoslavia or DFY), was a provisional state established during World War II on 29 November 1943 through the Second Session of the Anti-Fascist Council for the National Liberation of Yugoslavia (AVNOJ). The National Committee for the Liberation of Yugoslavia (NKOJ) was its original executive body. Throughout its existence it was governed by Marshal Josip Broz Tito as prime minister.

It was recognized by the Allies at the Tehran Conference, along with the AVNOJ as its deliberative body. The Yugoslav government-in-exile of King Peter II in London, partly due to pressure from the United Kingdom, recognized the AVNOJ government with the Treaty of Vis, signed on 16 June 1944 between the prime minister of the government-in-exile, Ivan Šubašić, and Tito. With the Treaty of Vis, the government-in-exile and the NKOJ agreed to merge into a provisional government as soon as possible. The form of the new government was agreed upon in a second Tito–Šubašić agreement signed on 1 November 1944 in the recently liberated Yugoslav capital of Belgrade. This Yugoslavia became one of the founding members of the United Nations upon the signing of the UN Charter in October 1945.

The Government of the Kingdom of Yugoslavia in Exile (Serbo-Croatian: Vlada Kraljevine Jugoslavije u egzilu, Влада Краљевине Југославије у егзилу) was an official government-in-exile of Yugoslavia, headed by King Peter II. It evacuated from Belgrade in April 1941, after the Axis invasion of the country, and went first to Greece, then to Palestine, then to Egypt, and finally, in June 1941, to the United Kingdom. Hence, it is also referred to as the "Government in London" (Vlada u Londonu, Влада у Лондону). It was dissolved in March 1945.

The Tito–Šubašić Agreements (Serbo-Croatian: sporazumi Tito-Šubašić) are the result of a series of negotiations conducted by the leader of the Yugoslav Partisans, Josip Broz Tito, and the prime minister of the Yugoslav government-in-exile, Ivan Šubašić, in the second half of 1944 and early 1945. The agreements were designed to create a coalition government in post–World War II Yugoslavia that would be composed of representatives of the National Committee for the Liberation of Yugoslavia and the government-in-exile.

The negotiations and the resulting agreements were supported and promoted by the World War II Allies, especially the United Kingdom. The British saw the process as an opportunity to influence the formation of the post-war regime in Yugoslavia, which would otherwise be left entirely to Tito and, presumably, the Communist Party of Yugoslavia, which had spearheaded the Partisan resistance to the Axis occupation of the country. Tito saw the process as an opportunity to gain international diplomatic recognition of his power.
