The peace treaty signed in Ghent terminated the War of 1812, and established the order of status quo ante bellum. Although the treaty did not solve the problems which had caused the conflict, the British-American conflict had many direct and long-term consequences. The aim of this article is to present the most important ones, particularly for the United States and the American nation. As Albert Gallatin, the American Secretary of Treasure, wrote in 1816, the War of 1812 made the American nation stronger and more united. After the termination of the warfare, since 1815 the increase of the population in the USA has been noted as well as the growth of the American economy thanks to the more intense trade relations with Eu-rope, mainly with Great Britain. The article indicates the consequences of the War of 1812 for the In-dian tribes, the allies of the British fighting against the Americans, and for Canada, which was attacked by the American army during the war. After the War of 1812 four American-British commissions were founded to resolve the standing boundary issue between the USA and Canada. Their arrangements determined the boundary and closed the door for American expansionism in the northern direction. The collapse of the Spanish Empire and the founding of new republics in Latin Ameri-ca caused a change in the direction of the foreign policy of the United States: its concentration only on the Western Hemisphere which came to be referred to as the Monroe Doctrine in 1823.
