The first written record of Sanok in Ipatiev Chronicle dates back to 1150, when Geisa, the King of Hungary, crossed the Carpathians and annexed this place to his territorial possessions. In 1339, almost in 200 years, Sanok was given the Magdeburg law by Boleslaw-Yuri II and became a significant commercial and manufacturing centre in the south-eastern part of Poland. Historically it was the first Ukrainian town to receive the Magdeburg law. Since the midst of the XIVth century Sanok belonged to Poland and was a centre of Sanok Land as a part of Rus County. In 1668-1675 Przemyśl bishop Antoni Winnicki lived here (since that time Przemyśl bishops started to use the supplement 'Sanok' to their title). Since 1772 Sanok was a part of Austria as a district city and later as a county of the Kingdom of Galicia and Lodomeria with its capital in Lviv. During the existence of the Second Polish Republic (1918-1939) Sanok used to be a centre of the county in Lviv Voivodeship.
