|Ohio is a state in the Great Lakes region of the United States. Of the fifty states, it is the 34th largest by area, the seventh most populous, and the tenth most densely populated. The state’s capital and largest city is Columbus. Ohio is bordered by Pennsylvania to the east, Michigan to the northwest, Lake Erie to the north, Indiana to the west, Kentucky on the south, and West Virginia on the southeast.
The state takes its name from the Ohio River, whose name, in turn, originated from the Seneca word ohiːyo’, meaning “good river”, “great river” or “large creek”. Partitioned from the Northwest Territory, Ohio was the 17th state admitted to the Union on March 1, 1803, and the first under the Northwest Ordinance. Ohio is historically known as the “Buckeye State” after its Ohio buckeye trees, and Ohioans are also known as “Buckeyes”.
Ohio rose from the wilderness of Ohio Country west of Appalachia in colonial times through the Northwest Indian Wars as part of the Northwest Territory in the early frontier, to become the first non-colonial free state admitted to the union, to an industrial powerhouse in the 20th century before transitioning to a more information and service-based economy in the 21st.
The government of Ohio is composed of the executive branch, led by the governor; the legislative branch, which comprises the bicameral Ohio General Assembly; and the judicial branch, led by the state Supreme Court. Ohio occupies 16 seats in the United States House of Representatives. Ohio is known for its status as both a swing state and a bellwether in national elections. Seven presidents of the United States have been elected who had Ohio as their home state.
