A national academy is an organizational body, usually operating with state financial support and approval, that co-ordinates scholarly research activities and standards for academic disciplines, most frequently in the sciences but also the humanities. Typically the country's learned societies in individual disciplines will liaise with or be co-ordinated by the national academy. National academies play an important organizational role in academic exchanges and collaborations between countries.

The extent of official recognition of national academies varies between countries. In some cases they are explicitly or de facto an arm of government; in others, as in the United Kingdom, they are voluntary, non-profit bodies with which government has agreed to negotiate, and which may receive government financial support while retaining substantial independence. In the countries of the former Soviet Union, and in the People's Republic of China, the national academies have considerable power over policy and personnel in their areas. There is however a growing consensus among international federations of learned academies that bona fide national (or learned) academies need to adhere to certain criteria:

Abraham Lincoln ⁱ/ˈeɪbrəhæm ˈlɪŋkən/ (February 12, 1809 – April 15, 1865) was the 16th President of the United States, serving from March 1861 until his assassination in April 1865. He successfully led his country through its greatest constitutional, military and moral crisis – the American Civil War – preserving the Union while ending slavery, and promoting economic and financial modernization. Reared in a poor family on the western frontier, Lincoln was mostly self-educated. He became a country lawyer, a Whig Party leader, Illinois state legislator in the 1830s, and a one-term member of the United States House of Representatives in the 1840s. After a series of debates in 1858 that gave national visibility to his opposition to the expansion of slavery, Lincoln lost a Senate race to his arch-rival Stephen A. Douglas. Lincoln, a moderate from a swing state, secured the Republican Party nomination. With almost no support in the South he swept the North and was elected president in 1860. His election was the signal for seven southern slave states to declare their secession from the Union and form the Confederate States of America. The departure of the Southerners gave Lincoln's party firm control of Congress, but no formula for compromise or reconciliation was found. And the war came.
