1861 - Washington Peace Conference
The last known national convention of the states was called by the Virginia legislature.
After the election of Abraham Lincoln as President, our nation was a powder keg, ready to explode over the issue of slavery. Some states had already succeeded from the union.
In February of 1861 to avert war, the Washington Peach Conference convened at the Willard Hotel in Washington DC. It was a convention of the states to discuss an amendment regarding slavery.
The assembly followed the convention rules established during the 18th century, which were well known at the time.
