U.S. President John Tyler vetoes a bill which called for the re-establishment of the Second Bank of the United States. Enraged Whig Party members riot outside the White House in the most violent demonstration on White House grounds in U.S. history.

The president of the United States (POTUS) is the head of state and head of government of the United States. The president directs the executive branch of the federal government and is the commander-in-chief of the United States Armed Forces.

John Tyler was the tenth president of the United States, serving from 1841 to 1845, after briefly holding office as the tenth vice president in 1841. He was elected vice president on the 1840 Whig ticket with President William Henry Harrison, succeeding to the presidency following Harrison's death 31 days after assuming office. Tyler was a stalwart supporter and advocate of states' rights, including regarding slavery, and he adopted nationalistic policies as president only when they did not infringe on the states' powers. His unexpected rise to the presidency posed a threat to the presidential ambitions of Henry Clay and other Whig politicians and left Tyler estranged from both of the nation's major political parties at the time.

The Second Bank of the United States was the second federally authorized Hamiltonian national bank in the United States. Located in Philadelphia, Pennsylvania, the bank was chartered from February 1816 to January 1836. The bank's formal name, according to section 9 of its charter as passed by Congress, was "The President, Directors, and Company, of the Bank of the United States". While other banks in the US were chartered by and only allowed to have branches in a single state, it was authorized to have branches in multiple states and lend money to the US government.

The Whig Party was a mid-19th century political party in the United States. Alongside the Democratic Party, it was one of two major parties from the late 1830s until the early 1850s and part of the Second Party System. As well as four Whig presidents, other prominent members included Henry Clay, Daniel Webster, Rufus Choate, William Seward, John J. Crittenden, and John Quincy Adams. The Whig base of support was amongst entrepreneurs, professionals, Protestant Christians, the urban middle class, and nativists. It had much less backing from poor farmers and unskilled workers.
