Henderson county is named for a county in Kentucky which in turn was named for Colonel Richard Henderson, founder of the "Nation of Transylvania" in 1778 in what is now Kentucky.
The county was established in 1841 and is located in western Illinois on the banks of the Mississippi River.
Points of interest in the county include the United Methodist Church in Oquawka, the county seat. It has been in continuous use since 1842.
