Douglas was a big part of popular sovereignty. He worked in the law field, but only because it was his easiest access into the political field. He is the one that introduced the controversial Nebraska Act. He also introduced popular sovereignty, which was not exactly one of his best ideas. This caused several conflicts because people who believed in very different things, started to physically fight for what they wanted. For example, free states and slave states both wanted to make all of America the same of what they believed in. with Douglas’s proposal of popular

Summary;                                                                                                                                                                                                        Popular sovereignty is letting the people of the state choose whether they want to be a free state or a slave state. They hoped this would balance out the amount of free and slave states. The Kansas Nebraska act of 1854, written by Stephen A. Douglas, created two territories that were given the choice. This caused much conflict because the north sent in citizens to make the state a free state. The south sent citizens to make the state. These events were very violent and some say it was a major cause of the U.S. Civil war. This showed that resolving these problems politically was virtually impossible. The US civil war was imminent and could not be stopped.                                                                                                                                                                                                                                                                                                                                                                                                                                                People/ Places                                                                                                                                                                                  The federal government- they created the idea of popular sovereignty                                                                               Stephen A.

However this caused much conflict and violence. Free and Slave states would send people into these new territories to convert the territory into the state they wanted. There were many skirmishes that often left people dead. This made the tensions between the North and South raise and lead to war.
