Sanation

Sanation was the political movement of Józef Piłsudski and his supporters, who took power in Poland in the May Coup of 1926 and governed until the German invasion of 1939. Its name came from its stated aim of restoring the moral health of public life after years of unstable parliamentary government. The regime grew increasingly authoritarian, imprisoning opposition leaders at Brest in 1930, and after Piłsudski's death in 1935 it was led by his followers.
