Daugavpils is a major railway junction and industrial centre and was an historically important garrison city lying approximately midway between Riga and Minsk, and between Warsaw and Saint Petersburg.
Daugavpils, then Dyneburg, was the capital of Polish Livonia while in Polish–Lithuanian Commonwealth. Following the first partition of Poland in 1772, the city became part of the Russian Empire.
