Lech II le Noir
In 1287, Busko was granted civic rights by King Leszek II the Black. The advantageous location of the town on trade routes led King Władysław Jagiełło to grant local burghers the right to have a weekly market and two fairs a year beginning in 1412. The 15th and 16th centuries were considered the "heyday" of the town. It was famous for its trade and cloth production.
