States proposed by Thomas Jefferson, including Chersonesus, Assenisippia, and Pelisipia.
His states were ideal American states, drawn on the map with a ruler and based on the sacred shape, the rectangle. In order to keep the lines straight, he had to squeeze a small state in and named it after Washington. The holy straight lines also split the State of Michigania in two parts without any access to each other.
Sadly, these works of Enlightment were never realized, and Jefferson's last years were ruined by his bitterness.
(These proposals are real.)
