The Polish government-in-exile was established during World War II after Poland was invaded by Nazi Germany in 1939. It aimed to represent Polish interests and maintain the continuity of the Polish state while operating from abroad, primarily in London. This government was recognized by several Allied nations and worked to rally support for Poland's liberation. The government-in-exile was led by figures such as Władysław Sikorski, who served as Prime Minister and Commander-in-Chief of the Polish Armed Forces. Despite its efforts, the government faced challenges, including the shifting political landscape in post-war Europe and the establishment of a communist regime in Poland, which ultimately undermined its authority.
