Answer: True
Explanation: Constantine was a Roman emperor who ruled from 306 to 337. Constantine got into to the throne as Emperor of Rome after the death of his father and due to the loyalty of his troops. At the beginning of his government, the empire was a tetrarchy (government of four rulers) until 313, in which Licinius (emperor of the east) and Constantine imposed themselves over the other emperors, establishing themselves as emperors of east and west respectively. In spite of the above, Constantine considered himself stronger than Licinius, so he decided to start a frontal attack of him that emerged victorious in 326, becoming the only emperor of the empire and taking all the eastern territories. There he founded a city with his name, Constantinople in present-day Istanbul (Turkey). Therefore, the correct answer is True.
