Frederick IV and I, Emperor of Germany (1831-1900? born Friedrich Wilhelm Nikolaus Karl von Hohenzollern) was German Emperor and King of Prussia (as well as, eventually, King of Westphalia) between his father's (William I, German Emperor) death in June 2, 1878, and his own death. Known informally as Fritz, Frederick IV was the only son of Wilhelm I and was raised as the heir from an early age. However, he did not inherit his father's conservative policies; instead, he developed pro-British, Liberal sentiment through his tutors.
