Manifest Destiny and the Mexican War of 1846

I choose The Missouri Compromise and The California Gold Rush from the selection. One of the most impactful historical events is The Missouri Compromise in 1820, amid expansion of the sectional tension in the slave trade. In light of slave trade, the U.S Congress adopted the law that brought Missouri on board to make it a free state. Additionally, there came a ban on slavery on the Louisiana Purchase land and thus ending the illegal trade (Herschbach, 2019). The impact was heavily felt on the enslaved people who could enjoy freedom and have rights. Therefore, with the Law being passed by the U.S congress, the Westward expansion took off with ease and started from Louisiana Purchase which was later promoted by Gold Rush.

The main effect of the Missouri Compromise was the huge number of free and slaveholding states that stayed the same. The issue later affected the balance of power in Congress. During this period, slavery was considered a divisive issue in the country and thus affecting the overall outcome. IN 1820, the enactment of the power balance issue came, hence the affirmation of Missouri to become a free state (Monaghan, 2019). AS a result of Missouri becoming a free state, the manifest ideology was later coined in 1846 and thus foresaw the expansion of dominion and the spread of democracy and capitalism. In a nutshell, The Missouri Compromise destiny led to the Southern slave trade glitches and the aim was diversify the territories, which could elevate Congress powers and, at the same time, attempt to keep the balance between enslaved person and Free State in 1820. On the other hand, The California Gold Rush sparked rejuvenated and pushed for the idea of Manifest Destiny. In the long, it attracted many individuals the region, thus enacting the gold and land claims, which was the dream of the west.
