This formally brought the American Revolution to a close. England recognized the independence of the United States. In addition, the United States secured all of the land east of the Mississippi River except for British possessions in Canada and Spanish territory in Florida.  Gained 7 new territories.
With this land, a lot of the land was in the North which didn't allow slavery, but the south did. In which the South probably wanted more land because they didn't get as much as the North and couldn't build out.

The point of the Northwest Ordinance was to have three to five new states that would not allow slavery.  Pro-slavery southerners were willing to go along with this because they hoped the new states would be populated by white settlers from the South.

But southerners would not join the abolishment movement because they still wanted slavery and they only agreed to the Northwest Ordinance in hopes to help them. I think this caused some tension between the two because the South wanted something from this but they didn't receive much.

This compromise meant that enslaved people would be counted in population totals for representation. So 3/5's of the total enslaved people per state.
While the three-fifths compromise brought all of the states on board to ratify the Constitution, regional differences and continuing debates over slavery, representation, and laws ultimately caused a bloody civil war. There was no getting around that the North didn't think it was fair that the South counted people that didn't even get the right to have a say or to vote or anything.

The chief executive has the power and duty to suppress all riots or insurrections in the interest of maintaining law and order.  It also included slaves insurrections.
This would lead to the civil war because not all slaves agreed that the chief executive should have the power. After all, for them, it didn't mean good things. The North also didn't think this was fair for slaves because they didn't want slavery so they wanted to help the slaves escape or make the South free, causing the war.

This event lead to the civil war because the land was open to America. The North and South wanted to use it for different reasons. The South wanted the open area to be used for the slaves and the North didn't want any slaves. There were also already natives living in some of the areas and the natives didn't want to be a part of the slave area.

This is known as the Importation Clause, and it meant that Congress was not allowed to ban the Atlantic slave trade for at least 20 years.
The South of course was in favor of this because they wanted slaves they were the ones who wanted this to stay in tac. But the North, however, did not. They didn't think slavery was appropriate and didn't think the country should allow slavery. Meaning the North fought over this issue and eventually it lead to the civil war.

This imposed heavy penalties on international traders. However, it did not end slavery or the domestic trade of slaves. Ships were often caught bringing in slaves illegally after this act.

The Spanish Cession was between the United States and Spain in 1819 that ceded Florida to the U.S. and defined the boundary between the U.S. and New Spain.

Oregon Country was one of the first Manifest Destiny successes. At one point the last was split between America and Britain. We wanted this territory because it would give America access to the Pacific Ocean.

The Mexican Cession happened after the Mexican-American war from 1846 to 1848. Mexico ceded 55 percent of its territory, including parts of present-day Arizona, California, New Mexico, Texas, Colorado, Nevada, and Utah, to the United States.
Because of the Mexican Cession bringing more states into America, there again was this huge argument over the states to be slave states or free states. With the extra space the North and South fought over the land, thus was the civil war.

In the compromise, California was admitted to the Union as a free state and the remainder of the Mexican cession was divided into the two territories of New Mexico and Utah and organized without mention of slavery.
This compromise leads to the civil war because both the North and the South were fighting over slavery, and right before this act, a war in 1846 broke out with Mexico, which didn't help the decision when making this compromise.

This act provided for the seizure and return of runaway slaves who escaped from one state into another or federal territory. Meaning any slaves that ran away to the North or a different state would have to be returned.
This was great for the South because they would get their slaves back each time. But the North didn't want slavery and fought to keep the slaves in the North so they could be safe. It wasn't fair to the slaves and the North noticed and tried to act on it. Causing the South to get angered and leading to a fight.

The violence when Preston Brooks hit Charles Sumner with his cane caused tension between the North and the South. This tension caused more issues between the North and South causing the civil war to come upon them.

# data[].attributes.body
During this event, a representative Preston Brooks, a pro-slavery Democrat from South Carolina used his own walking cane to attack senator Charles Sumner, an abolitionist Republican from Massachusetts. He did this because Brooks felt that during Sumner's speech he insulted his relative Andrew Butler.
This leads to the civil war because not only do the North and South not get along but they start to attack each other. Saying things in a speech is different that physically attacking them. They didn't want this anymore so it lead to the war to solve the issue.
