Page "Rzeszów" Paragraph 5

In the 5th century, first Slavs appeared in the area, which is confirmed by numerous archeological findings.

Most probably, Rzeszów was then inhabited by the Vistulans.

Some time between 11th and 13th century, the town was annexed by the Ruthenians, and Polish princes of the Piast dynasty confirmed it in 1264, when in Tarnów, there was a meeting of Prince Bolesław V the Chaste, and Prince Daniel of Galicia, during which both sides agreed that the border would go between Rzeszów and Czudec ( Rzeszów belonged to Red Ruthenia, while Czudec and Strzyżów to Lesser Poland ).
