Constans II
September 641 to July 15, 668 AD
Constans II, also called "Constantine the Bearded", (November 7, 630–September 15, 668) was Byzantine emperor from 641 to 668. He also was the last emperor to become consul in 642, becoming the last Roman consul in history. Constans is a diminutive nickname given to the emperor, who had been baptized Herakleios and reigned officially as Constantine. In 663 Constans visited Rome for 12 days—no emperor having set foot in Rome for two centuries—and was received with great honor by Pope Vitalian (657–672). Although on friendly terms with Vitalian, he stripped buildings, including the Pantheon, of their ornaments and bronze to be carried back to Constantinople, and declared the Pope of Rome to have no jurisdiction over the Archbishop of Ravenna, since that city was the seat of the exarch, his immediate representative. His subsequent moves in Calabria and Sardinia were marked by further strippings and request of tributes that enraged his Italian subjects. Rumours that he was going to move the capital of the empire to Syracuse were probably fatal for Constans. On September 15, 668 he was assassinated in his bath by his chamberlain. His son Constantine succeeded him as Constantine IV.
