Friedrich IV

Friedrich IV (b.1941 d.1988) was the only son and heir of Wilhelm IV, King of Prussia. A skilled horseman and hunter, he was also something of a playboy whose unhappy marriage resulted in no children. He admitted to having sired no less than three illegitimate offspring, however. Upon ascending to the throne at age 33, he refused to settle down and continued his partying ways. Rumors of drunkenness were common during his reign, as well as that he'd tried illegal narcotics. His death at age 48 was a surprise. Some claim the official cause--a heart attack--was a cover up for a drug overdose. He was succeeded by his sister.
