Bolko II the Small (Polish: Bolko II Maly (Swidnicki), German: Bolko II (Schweidnitz); c.
1312 – 28 July 1368), was the last independent Duke of the Piast dynasty in Silesia.
He was Duke of Swidnica from 1326, Duke of Jawor and Lwówek from 1346, Duke of Lusatia from 1364, Duke over half of Brzeg and Olawa from 1358, Duke of Siewierz from 1359, and Duke over half of Glogów and Scinawa from 1361.
He was the oldest son of Bernard, Duke of Swidnica, by his wife Kunigunde, daughter of Wladyslaw I the Elbow-high, Duke of Kuyavia and, from 1320, King of Poland.
Like his grandfather, King Elbow-high, Bolko II was of small stature; his nickname, "the Small" (Maly), reflects this and was used in contemporary sources.
