Why is Illinois called Illinois?

The state of Illinois was named after the Illinois River. The Illinois River was named by French explorer Robert Cavelier Sieur de La Salle in 1679 after the Indians he found living along the banks. Illinois is the French spelling for the Illinois and Peoria Indian word "iliniwok," meaning men or warriors and perhaps referring to members of the Illinois tribe.
