The search for a new capital for Nigeria began in earnest on 9th August, 1975, when the Federal Military Government set up the Justice Akinola Aguda panel to examine the dual role of Lagos as both Federal and State Capital and advice on the desirability or otherwise of Lagos retaining that role.
Where it decided that the Federal and not the State should move, the panel was to recommend a suitable alternative site as the new FederalCapital.
The panel submitted its report in December 1975 and declared Lagos incapable of shouldering the dual role of being the nation's Capital as well as that of State in addition to being the commercial and industrial nerve-centre of the country.
The ACT was created specifically to be the home of the federalcapital, Canberra, in order to avoid situating the new nation's capital in either of New South Wales and Victoria, the two most populous states at the time of federation.
The seat of the U.S. federal government in Washington is a federal district known as the District of Columbia.
There are also federal judicial circuits, each consisting of a group of states (except for the District of Columbia Circuit which consists only of the federal district); Puerto Rico and the United States territorial courts are also assigned to circuits.
