The Yugoslav government-in-exile was established during World War II after the Axis powers invaded and occupied Yugoslavia in 1941. This government was formed to represent the interests of the Yugoslav people and to coordinate resistance efforts against the occupiers. It was based in London and included various political factions, including royalists and communists. Led by King Peter II, the government sought international support and recognition while working with Allied forces. It aimed to restore Yugoslavia's sovereignty and promote unity among its diverse ethnic groups. The government-in-exile played a crucial role in maintaining Yugoslav identity during the war.
