It was admitted to the Union on March 1, 1803, as the 17th state. Ohio is one of the country's major industrial centers.[3] In addition to industry, its other major sources of income are finance, coal mining (which helped make Ohio one of the nation's leading industrial powerhouses) , agriculture and tourism. The rapid industrialization of the state made various native people stand out for their inventions and pioneering.[4] Thomas Edison was born in Ohio and the Wright brothers (known worldwide for having been the first to fly in an airplane, although in this regard there are controversies) also grew here.

The word "Ohio" means in the Iroquois language "Great River", "Long River" or "Beautiful River",[5]​[6]​[7] used by this group of Native Americans to describe the Ohio River. Ohio's nickname is the Buckeye State (the Buckeye is a chestnut tree of the genus Aesculus). Forests made up of trees of the genus Aesculus formerly covered all of Ohio, although many of these forests have been cleared to provide raw materials for various industries, as well as to make room for agriculture.[3] Ohio also lays claim to the nickname the Mother of Modern Presidents (Mother of Modern Presidents),[7] due to the fact that seven of the presidents of the United States were born and raised in Ohio, although this title belongs, in fact, to Virginia, with a total of eight presidents. U.S. Presidents born in Ohio include Ulysses S. Grant, Rutherford B. Hayes, James A. Garfield, Benjamin Harrison, William McKinley, William Howard Taft, and Warren G. Harding.[6] An eighth President, William Henry Harrison, lived in Ohio when he was named president.



The first European explorers to traverse the region were the French. Until 1763, the Ohio region was part of the French colony of New France, which then came under British control. With independence from the United States and the signing of the Treaty of Paris in 1783, the United States came to control the region. Ohio became the first territory of the Northwest Territory to be raised to statehood, and the 17th to enter the Union, on March 1, 1803.[8] The westward expansion and construction of Numerous railroads in the state, the discovery of numerous coal deposits and a strong agricultural industry made Ohio a great industrial power in the mid-nineteenth century. Ulysses S. Grant, born in Ohio, was one of the main leaders of the Union during the American Civil War.
