Photography

Sources contend that In 1843 Adams sat for the earliest confirmed photograph still in existence of a U.S. president, although others maintain that William Henry Harrison had posed even earlier for his portrait, in 1841.^[104] The original daguerreotype is in the collection of the National Portrait Gallery of the Smithsonian Institution.^[105]

Nullification crisis

Shortly after Adams entered Congress, the Nullification Crisis threatened civil war over the Tariff of 1828. Adams offered an amendment moderating the tariff, and defused the crisis. Congress also passed the Force Bill which authorized President Andrew Jackson to use military force if Adams' compromise bill did not force the belligerent states to capitulate. There was no need, however, because Adams' compromise remedied the matter. The compromise actually did not alter the tariff as much as the southern states had hoped, though they agreed not to continue pursuing the issue for fear of civil war.^[5]
