Because whoever got elected would dtermine whether Texas would be a slave state and whether Texas would get annexed
Westward expansion caused problems between the north and south because, as the states there were becoming free and slave states, disagreements between abolitionists and slave owners grew to tall heights since both wanted their new home to support their ideals. This transferred to the north and south since most northerners wanted the United States to be slave free and most southerners wanted to preserve slavery in order to promote their economical and social status.
At slave-auctions, which were widely advertised
too many Slave states being added to the Union
The slave trade? The Europeans.
Because as we pushed westward more slave states were added to the union increasing the slave population
It rose the question of whether each new state entered would be a slave state or a non-slave state. They needed to keep the slave states equal to non-slave states.
Westward expansion created territories that eventually wished to become States. Every application for Statehood prior to the Civil War increased sectional tension because of the need to balance "free" and "slave" States in Congress.
Slavery played a significant role in westward expansion in the United States. The expansion of slavery into new territories and states fueled sectional tensions between the North and South, eventually leading to the American Civil War. The issue of whether new states would allow or prohibit slavery was a major factor in determining the balance of power between the free and slave states, and ultimately the course of westward expansion.
It made the issue even more prevalent. People had the decision to make a state free or a slave state.
Because it was getting harder to create new slave-states, so the South was increasingly outvoted in Congress.
Fierce debate over which of the new states could be slave-states and which could be free soil.
The new states became the object of competition for North and South. The North increasingly needed to appease the Abolitionist lobby in Congress. The South wanted more slave-states, to extend its cotton empire, and also to maintain its influence in Congress and prevent it from passing laws that favoured the North.
The Missouri Compromise of 1820 temporarily settled the dispute over the westward expansion of slavery. It allowed Missouri to enter the Union as a slave state, Maine as a free state, and prohibited slavery north of the 36°30′ parallel in the Louisiana Territory.
Because it was getting more difficult to create new slave-states, and the South was in danger of being outvoted in Congress.
During the preface of Manifest Destiny, Americans were united in the idea that expansion would cause the country to flourish and thrive, but as sectional tensions between North and South began to increase, the North and other abolitionists started to reject Manifest Destiny. This is because the introduction of new slave states into the country would cause the North to lose their power within the nation.
