Settlement of the area which now comprises Tinley Park began in the 1830s, around the time of the foundation of Chicago. The first settlers were German, and the village was originally established in 1853 as "Bremen".
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 27th, 1892.
