Latin is a classical language belonging to the Italic branch of the Indo-European languages. Considered a dead language, Latin was originally spoken in Latium, the lower Tiber area around Rome. Through the expansion of the Roman Republic it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when regional vernaculars supplanted it in common academic and political usage. For most of the time it was used, it would be considered a dead language in the modern linguistic definition; that is, it lacked native speakers, despite being used extensively and actively.
