On December 10, 1924, the Village Board held a special meeting with representatives from the [[Soo Line Railroad]], who requested that the board change the village's name to Mundelein (for the cardinal). The board voted to make the change and asked the Illinois Secretary of State to make the name change. They received permission in April 1925, and the Village Board passed an ordinance changing the village's name to Mundelein.<ref name=":5" />
