IN 312 B.C.
In 190 B.C., when the Romans crushed the Macedonian army at the historic battle of Magnesia, after the Treaty of Apamea (188 B.C.), the entire Cappadocia or Asia Minor territory was surrendered to Rome. Built in the seventh century B.C., the ancient city of Byzantium proved to be a valuable city for both the Greeks and Romans. Because it lay on the European side of the Strait of Bosporus, the Emperor Constantine understood its strategic importance and upon reuniting the Empire in 324 A.D. built his new capital there Constantinople. The Byzantine Empire, also referred to as the Eastern Roman Empire and Byzantium, was the continuation of the Roman Empire in its eastern provinces, such as the Royal House of Cappadocia with its Imperial/Royal Order of Constantine the Great and Saint Helen.
