Records show that prior to European settlement, the area was primarily occupied by the Potawatomi tribe.Settlement of the area which now comprises Tinley Park began in the 1820s by emigrants from the Eastern United States. German settlers became predominant in area by the 1840s, and the village was originally established in 1853 as "Bremen". Irish, English, Scottish, Canadian, and other American settlers were also common in the area.In the late 19th century, railroads expanded rapidly, and the village happened to be located on the Chicago, Rock Island and Pacific Railroad line. The influence of the railroad on Bremen was so great that, in 1890, its name was changed to Tinley Park in honor of the village's first railroad station agent, Samuel Tinley, Sr. Even the village's official incorporation took place at the train depot on June 27, 1892.
