He was a bitter opponent of the Teutonic Order,[g] and its Grand Master once referred to him as "the devil incarnate".[h] In 1489 Watzenrode was elected Bishop of Warmia (Ermeland, Ermland) against the preference of King Casimir IV, who had hoped to install his own son in that seat.[22] As a result, Watzenrode quarreled with the king until Casimir IV's death three years later.[23] Watzenrode was then able to form close relations with three successive Polish monarchs: John I Albert, Alexander Jagiellon, and Sigismund I the Old. He was a friend and key advisor to each ruler, and his influence greatly strengthened the ties between Warmia and Poland proper.[24] Watzenrode came to be considered the most powerful man in Warmia, and his wealth, connections and influence allowed him to secure Copernicus' education and career as a canon at Frombork Cathedral.[22][i] ./cache/en-wikipedia-org-7597.html ./txt/en-wikipedia-org-7597.txt
