The first records of the village of Sosnowiec date back to 1727. The name Sosnowiec comes from pine forests originally growing in these areas.

As a result of the third partition of Poland, the village was incorporated into Prussia. It was there that the borders of the three partitions met forming the triangle of the three emperors between the Czarna Przemsza and the Biała Przemsza Rivers.

It became part of the Duchy of Warsaw in 1807 and of Congress Poland (the Kingdom of Poland) in 1815.

In the 19th century new deposits of hard bituminous coal were discovered. In 1859 a railway station was built with a branch of Warsaw – Vienna Railway. Consequently, the village started to develop.

The areas attracted industrialists from western countries. Due to the dynamic growth, Sosnowiec was granted a charter in 1902.
