After the construction of the railway line from Yuzovka to Mariupol in 1882, much of the wheat grown in the Yekaterinoslav Governorate and coal from the Donets Basin were exported via the port of Mariupol (the second largest after Odessa in the South Russian Empire), which served as a key funding source for opening a hospital, public library, electric power station and urban water supply system.
