Did Illinois used to be 2 states? Trying to make sense of this 1824 Electoral College map

by zardines

Here is the map

Did "A1" used to be it's own state? What was it called? Why did they eventually merge together? Or was it just a voting line and the state was effectively already one thing?

Curious to know the story.

It's just to show that the electoral vote was split in that state. One for Adams, two for Jackson.
