[1] The history of Koszyce dates back to the year 1328, when the village was for the first time mentioned in documents.

There are undocumented speculations that Koszyce had received town charter before that date, and Queen Elizabeth only confirmed this fact.

The town prospered in the 15th century, due to a location along an important merchant trail from Kraków to Sandomierz.

The town had a Holy Cross hospital and a parish school, and among its most famous residents was a physician named Jakub Grzywna, who moved to Koszyce from Kraków in 1520, and died here in 1531.

During the January Uprising, Koszyce was one of the most important centers of the rebellion, and as a reprisal, the town was stripped of its charter on June 1, 1869.
