city, Thuringia Land (state), eastern Germany. Weimar lies along the Ilm River, just east of Erfurt. First mentioned in documents in 975 as Wimare, it was declared a town in 1254 and was chartered in 1348. Ruled by the counts of Weimar-Orlamunde from 1247 to 1372, it then passed to the Saxon house of Wettin and became the capital of the duchy of Saxe-Weimar in 1547 and of the grand duchy of Saxe-Weimar-Eisenach in 1815 (until 1918). The German National Assembly, forming the constituent national representative body of the German Republic, which was created after the revolution of 1918-19, met in the city from February 6, 1919, and the constitution of the new republic (known commonly as the Weimar Republic and lasting until 1933) was drawn up there. Weimar was the capital of Thuringia from 1920 to 1948
