Vexilloid of the Roman Empire

The Roman Empire was an autocratic political entity which spanned the entirety of the Mediterranean during antiquity. Centered around the Italian city of Rome, the empire grew out of the Roman Republic following decades of political upheaval and civil war. The Roman Empire rose in 27 BCE with the rise of Augustus Caesar as its sole ruler, taking (among other titles) the role of imperator or emperor while maintaining the illusion that the republic had survived. The empire promoted its own imperial cult of deities which included the traditional Roman pantheon and deified past emperors, though beginning with the Constantinian dynasty of the 4th century, Christianity gained significant popularity until its proclamation as imperial state religion in 380 CE. With the centers of power shifting throughout the century from Rome to Constantinople, the Roman Empire was frequently split between two different emperors ruling separately over its eastern and western halves. This split was made permanent in 395. The Western Roman Empire fell in 476 AD with the deposition of emperor Romulus Augustalus by the Ostrogothic king Odoacer. This date is typically marked as the end of the Roman Empire by many historians. However, its eastern half, popularly known as the Byzantine Empire, would survive until the fall of Constantinople in 1453. Many nations have claimed succession from the Roman Empire, such as the Russian Empire, the Ottoman Empire, Italy under Benito Mussolini, and the United States.
