Romanus II (939 - 963) succeeded his father Constantine VII as Byzantine emperor in 959 at the age of twenty-one, and died, poisoned, it was believed, by his wife, Theophanu in 963. Their daughter, also Theophanu married Otto II, Holy Roman Emperor.
He was a pleasure-loving sovereign, but showed judgment in the selection of his ministers. The great event of his reign was the conquest of Crete by Nicephorus Phocas in 961.
