George Washington selected the site because of its central location
Explanation:
Unlike the deeply divided Washington of today, the founding of the US capital in Washington DC in 1790 was based on political compromise.
Alexander Hamilton and the Northern States wanted the federal government to deal with the state's debts and reached an agreement with Thomas Jefferson and James Madison, who wanted a capital in the South.
George Washington chose the exact spot on the Potomac River and the rest is history.
