John Huss was a Czech philosopher and theologian. He is credited with inspiring a Proto-Protestant Christian movement called Hussitism, which started in the Kingdom of Bohemia before spreading across the Lands of the Bohemian Crown. He also inspired the Bohemian Reformation, which is regarded as one of the most important social, political, and religious movements of the early modern period.
The First Secretary of the Communist Party of Czechoslovakia, Alexander Dubček, was no stranger to politics as a child, being the son of a Communist Party member. He resisted the Nazi occupation, while his liberal policies later led Soviet authorities to invade Czechoslovakia. He eventually died in a car crash.
Czech president Edvard Beneš had come to power twice and resigned in both instances, first after the German occupation of Czechoslovakia and then after the communist coup of 1948. Born to peasants in Bohemia, he had earned a doctorate of law and taught at universities before entering politics.
