Legacy of the Roman Empire
The legacy of the Roman Empire has been varied and significant. The Roman Empire, itself built upon the legacy of other cultures, has had long-lasting influence with broad geographical reach on a great range of cultural aspects, including state institutions, law, cultural values, religious beliefs, technological advances, engineering, and language. This legacy survived the demise of the empire itself (5th century AD in the West, and 15th century AD in the East) and went on to shape other civilisations, a process which continues to this day. The city of Rome was the civitas (reflected in the etymology of the word "civilisation") and connected with the actual western civilisation on which subsequent cultures built is the Latin language of ancient Rome, epitomized by the Classical Latin used in Latin literature, which evolved during the Middle Ages and remains in use in the Roman Catholic Church as Ecclesiastical Latin. Vulgar Latin, the common tongue used for regular social interactions, evolved simultaneously into the various Romance languages that exist today (notably Italian, French, Spanish, Portuguese, Romanian, Catalan, Sardinian, etc.). Although the Western Roman Empire fell in the 5th century AD, the Eastern Roman Empire continued until its conquest by the Ottoman Empire in
