In 1291–1392 Świdnica was the capital of the Piast-ruled Duchy of Świdnica and Jawor. The last Polish Piast duke was Bolko II of Świdnica, and after his death in 1368 the duchy was held by his wife until 1392; after her death it was incorporated into the Kingdom of Bohemia by Wenceslaus IV of Bohemia. By the end of the 14th century, Świdnica was already one of the largest cities in Silesia, with about 6,000 inhabitants.
