If there is conflict between a free state and slave states, it's very obvious why. Slave states have people working and working everyday and night, but in free states people get to do what they would like, whenever they'd like. They would have conflict because the "slave states" want to have what the free states have. I hope this helped.

In West Africa, the three most important empires were Ghana, Mali, and Songhai, all of which profited tremendously from the trans-Saharan gold trade. ... Their territorial holdings were eventually larger than either Mali or Ghana, until civil war irreparably weakened the empire.
Stephen Douglass was a Democrat elected to the U.S. Senate in 1858. Douglas defeated Abraham Lincoln to obtain his Senate seat. He was a supporter of the idea of popular sovereignty, the belief that the settlers in newly admitted territories should determine whether the area would be slave or free. Douglass received the Democratic nomination for president in 1860. Douglass support of popular sovereignty led to the splintering of the Democratic Party into Northern and Southern factions. Northerners opposed secession while Southerners supported it. The splintering of the party led to their defeat and the election of the Republican Abraham Lincoln in 1860.
