Compromise of 1850
The Compromise of 1850 was a series of five bills passed by the US Congress in September 1850 to diffuse a sectional crisis brewing between the 'free states' of the North and the 'slave states' of the South. The crisis was sparked by a disagreement over whether slavery should be allowed to expand into the so-called 'Mexican Cession', the 529,000 square miles of territory seized from Mexico after the Mexican-American War (1846-1848). Under the Compromise of 1850, California was admitted into the Union as a free state, while slavery in the rest of the territory – such as in New Mexico and Utah – would be decided through 'popular sovereignty,' meaning that settlers would decide on whether to prohibit slavery or not. This compromise did not resolve the dispute but only postponed the conflict over slavery that would culminate in the American Civil War (1861-1865).
Background: Mr. Polk's War
In 1844, James K. Polk (1795-1849) won election to the US presidency on a platform of expansionism; promising to lead the United States toward its 'Manifest Destiny', Polk declared his intention to wrest the Oregon Territory from the British, seize all Mexican territory north of 31°, and annex the newly independent Republic of Texas. Initially, this ambitious policy fell quite short of its goals. Polk was forced to settle for a treaty that established the Oregon boundary at the 49th parallel – less than was hoped for – while Mexico declined to sell any territory at all. But when Texas joined the Union in December 1845 as the 28th state, Polk saw a new opportunity for conquest; Mexico had not recognized Texas' independence and viewed its annexation by the US as a hostile act. Polk and his partisans continued to provoke Mexico, ultimately leading to the Mexican-American War. At the end of that conflict, Mexico was forced to give up vast amounts of territory, including Utah, New Mexico, and California. Polk had achieved his goal – by the end of his single term, the United States had expanded by two-thirds, growing more than it had under any other president.
Mr. Polk's War, as the conflict had been derisively called, was quite polarizing – while Polk's own Democratic Party supported the expansion of the United States by any means necessary, members of the Whig Party viewed the conflict as an unjust war and believed that its main objective had been to expand the institution of slavery and increase the political power of the slave-holding South. The Missouri Compromise of 1820 had fixed the boundary between 'slave states' and 'free states' by prohibiting slavery north of the 36°30' north latitude parallel. But since most of the land conquered from Mexico was beneath that boundary, several new 'slave states' could potentially be carved out from the territory. In 1846, anti-slavery representatives tried to prevent this with the Wilmot Proviso, which declared that "neither slavery nor involuntary servitude shall ever exist in any part" of the territory acquired from Mexico – the proviso passed in the House, but it was defeated in the Senate, where the South exerted greater power. Though the Wilmot Proviso failed, it rejuvenated the national debate over the question of slavery, an issue that had been festering beneath the country's surface for decades.
Opponents of slavery – often called Free Soilers – believed that the institution was not only a moral evil but also stood in the way of progress. As historian James M. McPherson writes, Free Soilers argued that "free labor was more efficient than slave labor because it was motivated by the inducement of wages and the ambition for upward mobility rather than by the coercion of the lash" (55). Slavery must therefore be kept out of the new territories to encourage free labor and progress there. But the slave-holding South interpreted these statements as an attack against its social system. As the global demand for cotton grew, Southern planters became more reliant on slave labor to cultivate the crop. Additionally, it was believed that slave labor was necessary to allow the slave-holding gentry time to cultivate the arts, literature, and to pursue public office. An attack on slavery was therefore viewed as an attack on the Southern way of life; to preserve this, Southerners sought to expand slavery wherever they could, to maintain a strong pro-slavery voting bloc in Congress.
The question of whether slavery would be allowed in the newly acquired territories threatened to dominate the US presidential election of 1848. Polk had declined to seek re-election; worn out by his time in office, he would be dead before the end of the decade. Instead, the Democrats nominated Senator Lewis Cass of Michigan, who championed the idea of 'popular sovereignty' – this meant that the settlers of the territories should decide for themselves whether they wanted slavery or not. The Whigs, needing to carry states where annexation had been popular, decided to avoid the question of slavery for the time being and nominated General Zachary Taylor (1784-1850), hero of the Mexican War. Taylor was an odd choice – he had been mostly unpolitical prior to his run for office, leaving many Americans unsure as to what his political positions were. However, he was a slaveholder who owned over a hundred slaves himself, leaving many pro-slavery voters feeling comfortable that he would support their position. Taylor won the election, carrying 8 of the 15 slave states, and was inaugurated on 4 March 1849. But little did anyone realize that Taylor's election heralded a political storm that was just about to break.
