Premislav of Tost
Premislav of Tost was a ruler in Silesia, sometimes known by his diminutive Primko. He was the second son of Duke Kasimir I of Silesia-Auschwitz.
Several years after his father's death Premislav received the dukedom of Tost, which he ruled for forty-five years. He died aged fifty-nine.
Duke Premislav was married to Machna, the eldest daughter of Duke Nikolaus I of Silesia-Oppeln. The couple left no male heirs, just a surviving daughter Margaret of Tost who took holy orders and was appointed abbess of the convent of St Klara in Breslau.
