Abraham Lincoln i/ / (February 12, 1809 – April 15, 1865) was the 16th President of the United States, serving from March 1861 until his assassination in April 1865. Lincoln led the United States through its greatest constitutional, military, and moral crisis—the American Civil War—preserving the Union, abolishing slavery, strengthening the national government and modernizing the economy. Reared in a poor family on the western frontier, Lincoln was self-educated, and became a country lawyer, a Whig Party leader, Illinois state legislator during the 1830s, and a one-term member of the United States House of Representatives during the 1840s. He promoted rapid modernization of the economy through banks, canals, railroads and tariffs to encourage the building of factories; he opposed the war with Mexico in 1846.
