Stolberg-Rossla
The County of Stolberg-Rossla was a county of the Holy Roman Empire. Its capital was Rossla, now in Saxony-Anhalt, Germany. It was owned and ruled by a branch of the House of Stolberg from 1341 until 1803.
Stolberg-Rossla emerged as a partition of Stolberg-Stolberg in 1706. It was forced to recognize the suzerainty of the Electorate of Saxony in 1738. Stolberg-Rossla was mediatised to Saxony in 1803, but passed to the Kingdom of Prussia in 1815. Although the territory was subsequently administered within the Province of Saxony, the counts retained their possessions until 1945. In 1893 they became Princes of Stolberg-Rossla.
