The correct answer to this open question is the following.
Unfortunately, you forgot to include a question. Here we just have a statement. What is your question? What do you want to know?
However, trying to help you we can comment on the following.
We are going to assume that you need to know the purpose of these laws, legislation, and events.
So Wilmot Proviso, Compromise of 1850, popular sovereignty, Fugitive Slave Act, Kansas-Nebraska Act, Anaconda Plan, freedmen, Gettysburg Address, and the Thirteenth Amendment intended to resolve the issue of slavery in newly acquired US territories and in all the southern territory.
For example, the case of the Wilmot Proviso.
After the United States won the Mexican-American War (1846-1848), it gained large territories. The Wilmot Proviso tried to eliminate the use of slaves in those recently acquired lands. It was David Wilmot, a Congressman from the state of Pennsylvania, who proposed this idea.
Or the case of the Reconstruction Amendments, the 13th, 14th, and 15th Amendments to the United States Constitution, that tried to help the African American people.
