"Duke Frederick of Saxony (26 October 1473 – 14 December 1510), also known as Friedrich von Sachsen or Friedrich von Wettin, was the 36th Grand Master of the Teutonic Knights, serving from 1498–1510. He was the third (and youngest surviving) son of Albert, Duke of Saxony, and Sidonie of Poděbrady, daughter of George of Podebrady.
The Teutonic Knights had been in a long power struggle with Poland over Prussia. Because the Teutonic Knights´ fortunes had declined throughout the 15th century, they hoped that by selecting someone connected by marriage to the ruling Jagiellon dynasty of Poland, they would strengthen their position." - (en.wikipedia.org 12.06.2020)
