What was the pro-slavery constitution in kansas?

The pro-slavery constitution in Kansas, known as the Lecompton Constitution, was drafted in 1857 by pro-slavery advocates in the Kansas Territory. It sought to establish Kansas as a slave state, despite the territory's strong anti-slavery sentiment. The constitution was controversial and faced significant opposition, leading to a national debate over slavery and contributing to the tensions that eventually escalated into the Civil War. Ultimately, it was rejected by Congress and Kansas entered the Union as a free state in 1861.
