The Baiuvarii, Bavarii, sometimes simply called Bavarians (German: Bajuwaren) were a Germanic people who lived in or near present day southern Bavaria, which is named after them.
They began to appear in records by the 6th century AD, and their culture, language and political institutions are the predecessors of those of the medieval Duchy of Bavaria and Margraviate of Austria.
Among the Baiuvarii the Bavarian language developed, which is West Germanic language related to Standard German, still spoken not only by modern-day Bavarians, but also by Austrians and South Tyroleans.
