Which empire was ruled from Constantinople for a thousand years?

The Byzantine Empire, also known as the Eastern Roman Empire, was the continuation of the Roman Empire centred on Constantinople during late antiquity and the Middle Ages. Having survived the events that caused the fall of the Western Roman Empire in the 5th century AD, it endured until the fall of Constantinople to the Ottoman Empire in 1453. The term 'Byzantine Empire' was coined in the 5th century but dropped once the Western part collapsed and used again only after its demise; its citizens used the term 'Roman Empire' and called themselves 'Romans'.
