41 years
If you date it from the Missouri Compromise (1820), the answer is forty-one years.
There was no Civil War while the Missouri Compromise was in force. It kept the peace for thirty years. It was the debate over the admission of California, following the Mexican War, that made the Missouri Compromise inoperable (because the new state extended so far on either side of the line) and a new Compromise had to be worked out. This one did not last.
The Misouri Compromise of 1820 delayed the Civil War for a generation. It was undone by the Compromise of 1850, and barely ten years after the end of the Missouri Compromise disunion and war came.

The Compromise of 1850 undid much of the work of the Missouri Compromise made a few years prior. Unfortunately, the Compromise of 1850 did not alleviate the tensions of the slave debate, and the Civil War broke out just ten years later.
The Missouri Compromise of 1820 lasted 30 years. The US remained divided on where slavery could exist and thus the Missouri Compromise of 1850 was enacted.
None. It was a successful compromise that kept the peace for thirty years.
There were a number of compromises made in the US leading up to the US Civil War. The list is as follows:1. In order to have the new US Constitution ratified, slavery was not slated for abolishment, but the importation of slaves would be illegal after 10 years. ( this was a hollow deal as slaves continued to be imported under cover) 2. The Missouri Compromise of 1820 to keep the balance of slave and free states equal; 3. The Missouri Compromise of 1850, this also to keep the slave-free state balance, but added the Fugitive Slave Law; and 4. The Kansas-Nebraska Act allowing citizens to vote on the slave issue when a territory had yet to apply for statehood.
