Saxe-Altenburg (German: Sachsen-Altenburg) was one of the Saxon duchies held by the Ernestine branch of the House of Wettin in present-day Thuringia.[2] It was one of the smallest of the German states with an area of 1323 square kilometers and a population of 207,000 (1905) of whom about one fifth resided in the capital, Altenburg. The territory of the duchy consisted of two non-contiguous territories separated by land belonging to the Principality of Reuss-Gera. Its economy was based on agriculture, forestry, and small industry. The state had a constitutional monarchical form of government with a parliament composed of thirty members chosen by male taxpayers over 25 years of age.
Territory
Saxe-Altenburg had an area of 1,323 km2 (510 sq. mi.) and a population of 207,000 in 1905. Its capital was Altenburg.
When Johann Wilhelm's son and successor Friedrich Wilhelm I died in 1602, the Duchy of Saxe-Weimar passed to his younger brother Johann II. In 1603 Frederick William's eldest son Johann Philipp received the newly created Duchy of Saxe-Altenburg as compensation. It was an Imperial State in its own right, with a vote in the Reichstag, for much of the 17th century until the extinction of its ruling line in 1672 when it was inherited by Ernest I the Pious, the Duke of Saxe-Gotha, who had married the heiress.
Saxe-Altenburg thereafter remained part of Saxe-Gotha-Altenburg until the extinction of that house in 1825, when Gotha and Altenburg were divided up, with Gotha going to the Duke of Saxe-Coburg-Saalfeld and Altenburg to the Duke of Saxe-Hildburghausen, who in exchange gave up Hildburghausen to the Duke of Saxe-Meiningen. This family ruled the duchy until the end of the monarchies in the course of the German Revolution of 1918–19. The succeeding Free State of Saxe-Altenburg was incorporated into the new state of Thuringia in 1920.
