Schwarzburg-Rudolstadt was a small historic state in present-day Thuringia, Germany, with its capital at Rudolstadt.
History
Schwarzburg-Rudolstadt was established in 1599 in the course of a resettlement of Schwarzburg dynasty lands. Since the 11th century, the ancestral seat of the comital family had been at Schwarzburg Castle, though after 1340, for most of its existence as a polity had the capital at the larger town of Rudolstadt. In 1583 Count Günther XLI of Schwarzburg, the eldest son of Günther XL the Rich and ruler over the united Schwarzburg lands, had died without issue. He was succeeded by his younger brothers, whereby Albert VII received the territory around Rudolstadt. After their brother William I, Count of Schwarzburg-Frankenhausen had died in 1597, the surviving brothers Albert VII and John Günther I established the two counties of Schwarzburg-Rudolstadt and Schwarzburg-Sondershausen by the 1599 Treaty of Stadtilm.
In 1905 Schwarzburg-Rudolstadt had an area of 940 km2 (360 sq mi) and a population of 97,000.
On 23 November 1918, during the German Revolution of 1918–1919 and the fall of all the German monarchies, Prince Günther Victor was the last to abdicate. The former principality became a "Free State" in 1919 and joined the Weimar Republic as a constituent state. In 1920, it joined with other small states in the area to form the new state of Thuringia.
