Sitting along the banks of the Mississippi River and Lake Michigan, Illinois’s accessible location has for centuries made it an important hub. Historically emigrants from Mexico, Ireland and Poland would make the long journey over in search of work and a new home. Abraham Lincoln was among those who called Illinois home and the state honoured him by naming the small city of Lincoln after him – before he became president.
