The area of southeastern Kansas known as the Little Balkans attracted immigrants from Europe to work in the coal mines.

The immigrants worked long hours in the mines, often in dangerous conditions, but they were able to earn a living and provide for their families. The Little Balkans region became a thriving community of European immigrants, and it played an important role in the development of the coal mining industry in Kansas.
