Manifest Destiny: Critical the growth of the U.S.A.
Thirteen to fifty thanks to manifest destiny. Manifest destiny is what the people thought was the God given right to have land from sea to shining sea (Manifest Destiny). Legal actions regarding manifest destiny were instrumental in the addition of land for the US. There were long term effects from the many compromises, wars, acts, elections and treaties. If there were no legal actions about manifest destiny, the union and confederacy wouldn’t have anything to have a war about. With the states beyond the first thirteen colonies, there was an opportunity to have a separation of the north and south.

Independence was won in the revolutionary war but the U.S. grew a lot after that. Nationalism spread quickly through the U.S. which made a high demand for more land. John O' Sullivan, a newspaper editor, started the term manifest destiny. Many settlers believed that God blessed the expansion of the "American nation" (Manifest Destiny). All the states that were included in the confederacy were a cause of the war. There wouldn't have been a war if none of those states were in existence, so manifest destiny, the addition of land in the U.S. was very critical.

1783: Original 13 Colonies
1803: Louisiana
(America In the Early 19th Century…)
1821: Florida
1845: Texas
1846: Oregon
1848: Mexican Session
1853: Gadsden
The treaty that sealed the deal for the Louisiana Purchase was critical in getting all 13 states included in that piece of land. The Us need to valuable port in New Orleans. Napoleon knew he would probably lose the land during the war and needed the money for the war. In 1803, Monroe signed the treaty to buy the land which would double the land size of the US, for only fifteen million dollars. Since Missouri, Nebraska, and Kansas were part of Louisiana, by buying it, it made states that were part of thing like the Missouri Compromise, making Missouri slave and main free, Kansas Nebraska act and also things like bleeding Kansas which cause friction with the two sides (Roop; Smith-Baranzini; New Hanover County Schools).

Gaining Texas had a snow ball effect on the US (New Hanover County Schools; Katz). Mexico warned the US to not annex Texas but when it did, we gained a large piece of land and that started the Mexican-American War. With Texas being in the south, and a huge producer of cotton, slaves were needed (New Hanover County Schools). If Texas wasn't annexed there would be one less state that was part of the rebellion of the confederate states.

Many countries claimed Oregon as their own. Before the annexation in 1846, Britain and U.S. "shared" it. Polk's campaign propaganda was that he would get all of Oregon. After the treaty was signed, the U.S. added all of Oregon south of the 49th parallel. In Oregon there wasn’t a huge demand for slaves so it was added as a free state the southern states didn’t like that they just lost another state to the union.

The Mexican session was an effect of the Mexico war. After Taylor went to south Texas, a war between US and Mexico began. The war officially started after a Mexican general sent a letter, April 11, 1846, telling the U.S. to go back to their own land, and the U.S. didn’t. Cannons were used a lot during the war. The final battle called Siege of San José del Cabo, ended the war. By 1848, the treaty of Guadalupe, was signed and California, New Mexico territory, and Utah territory were all part of the U.S. The U.S. gave Mexico 15 million dollars and the war was brought to an end.( Nardo). Since California, was included in the part of the land, the Mexican war was a cause of the civil War because California was instrumental in the Compromise of 1850 (New Hanover County Schools).

After 7 months of debate, the Compromise of 1850 was complete (Chambers). California wanted to become part of the US...
