Duchy of Oświęcim
The village was first mentioned in 1444 as "Bujakuov". Politically it belonged then to the Duchy of Oświęcim, a fee of the Kingdom of Bohemia. In 1457 Jan IV of Oświęcim agreed to sell the duchy to the Polish Crown, and in the accompanying document issued on 21 February the village was mentioned as "Buyakow".
