after charles iv there were many arguments and fights in prague. a priest called jan hus said that the catholic church had become too powerful. he was arrested and burned at the stake in 1415. a lot of people agreed with what hus had been saying. these people were called hussites. they threw a lot of important catholic people out of the window (called "defenestration"). a lot more fighting followed, and for many years bohemia was ruled by kings who lived in other countries.
