Congress Permanently Settles Slavery Question by Drawing Line, Vowing Never to Look at It Again

To keep the peace, the Union split the map at 36°30′, admitted one slave state and one free, and pronounced the gravest question in American life resolved.

What wasn’t broken
The Union was expanding, and each new state threatened the balance between slave and free. It was an argument the country genuinely needed to have. Instead it drew a map.
The "fix"
The Compromise of 1820 admitted Missouri as a slave state and Maine as a free one, preserving the Senate's tidy equilibrium, and ruled slavery permitted below the line of 36°30′ north and forbidden above it. The crisis passed. The country exhaled.
The result
It purchased thirty-four years, a respectable run for a postponement dressed as a settlement. The line held until 1854, when it was repealed; the question it was drawn to avoid arrived anyway, on schedule and with interest, at a fort in Charleston harbor. Thomas Jefferson, hearing the news, called it 'a fire-bell in the night.' Fuxed

The trouble began when Missouri asked to enter the Union as a state that permitted slavery. The Senate at that moment held eleven free states and eleven slave — a balance both sides guarded like a card hand — and Missouri would tip it. What followed was less a debate about Missouri than a sudden, unwelcome glimpse of the entire future.1

Henry Clay, ever the broker, assembled the escape hatch. Missouri would come in slave, Maine would come in free, and the ledger would stay even. For the territories not yet states, Congress drew a line at 36 degrees 30 minutes north and decreed slavery lawful below it, prohibited above. The scheme had the supreme political merit of requiring no one to decide anything on principle.2

Thomas Jefferson, in retirement at Monticello, was not consoled. The news, he wrote, reached him 'like a fire-bell in the night,' and he confessed he 'considered it at once as the knell of the Union.' A geographical line drawn upon a moral question, he warned, would never be rubbed out and would only burn deeper each year.3 On this occasion the old man was exactly right.

The line endured for thirty-four years, which a later generation mistook for success. The Kansas-Nebraska Act repealed it in 1854, and the question it had been drawn to defer came due at last, settling itself by the single means the Compromise had left on the table. The fix had not solved the problem. It had merely scheduled it.1

…like a fire-bell in the night, awakened and filled me with terror. I considered it at once as the knell of the Union.— Thomas Jefferson, letter to John Holmes, April 22, 1820
