Rudolf II

Emperor Rudolph II ruled from Prague in the 16th century. According to the Eleventh Doctor, his court attracted all sorts of people. During his reign, the Mavora attacked Prague. As a response, he gathered the greatest minds of the time to solve the problem. Rabbi Judah Loew ben Bezalel created a prison, The Sorrows of Prague, to contain the Mavora, and one of his courtiers, Gerhard Frankel defeated the rest by becoming the Golem of Prague.
