Why did the founding fathers want dc to be a federal district?

The Founding Fathers wanted Washington, D.C. to be a federal district to ensure that the nation's capital would be independent of any individual state’s influence and control. This separation was intended to promote neutrality, allowing the federal government to function without favoritism towards any particular state. By establishing a distinct federal district, they aimed to symbolize the unity of the states under a central government and to provide a location that represented the nation as a whole.
