The town of Błonie appeared in 1257. In 1338 Błonie was granted its town charter based on that of Magdeburg. In 1380 it obtained its town charter again, based on that of Chełmno.

Towards the end of the 15th century, Błonie became a very important trade center. In the middle of the 17th century the town was destroyed by the Swedes. During the Kościuszko Insurrection (Uprising), in 1794, the Polish Army fought the Prussians near Błonie. Since 1795 the town was under Prussian rule, since 1807 it transferred to the Duchy of Warsaw, and since 1815 it belonged to the Kingdom of Poland (Congress Poland). During World War I Błonie was partly damaged.

During World War II, in September 1939, it was occupied by the German Army. Polish guerilla groups were active near Błonie.
