Governor Edward Coles appointed Blackwell Illinois Secretary of State on April 2, 1823. Blackwell's goal in the position was to prevent a constitutional convention in which pro-slavery forces could reverse Illinois' de jure status as a free state.

The session adjourned February 19, 1827, and the assembly ended December 1, 1828.[2]
Blackwell died on March 28, 1832, in Belleville, Illinois.[1]
