Maine would have to join as a free state so Missouri could become a slave state.
It had to do with the Missouri Compromise, where both Missouri and Maine were applying for statehood. Maine was inducted as free, Missouri slave, and everything over the 36 30 line was free, except for Missouri. So who had to agree? The Senate and The House, so that they could get statehood. Without that, Maine would have been a state way later.
missouri's date of statehood is August 10, 1821.
