Eustachy Sapieha

On 16 June 1919, Sapieha was delegated as the ambassador of Poland to the United Kingdom. On 4 June 1920 he and Erazm Piltz, representing the Polish government, signed the Treaty of Trianon in Paris.

In 1920, he was chosen by Prime Minister Władysław Grabski to be Minister of Foreign Affairs. Although he successfully negotiated several agreements with Western powers, he was faced with the delicate situation over the plebiscites in Upper Silesia. On 24 March 1921 the British Embassy^[1] at Warsaw wrote to Earl Curzon in London to say that he had just called upon Prince Sapieha whom he found "very depressed at the result of voting in Upper Silesia, which has on the whole turned out far worse than the Polish Government had anticipated...He agreed with me that the victory reports in the newspapers were foolish and any public rejoicing regrettable."^[2] His negotiations over federation with Lithuania also failed and, faced with criticism from the National Democrats, he resigned his post later in the year.

In 1928–29 he was a Sejm deputy from the Nonpartisan Bloc for Cooperation with the Government. After the Soviet invasion of Poland in 1939 he was arrested by the Soviets and imprisoned in the Lubyanka prison. After the Sikorski-Mayski Agreement, he joined Anders' Army. In 1941 he travelled to Kenya. He did not return to post-war communist Poland, and remained in Nairobi.

In 1956 he was awarded the Order of the White Eagle by the Polish government in exile.
