It includes the Local Government Areas of the City of Darwin, the northern part of the City of Palmerston and part of the north-western edge of the Shire of Litchfield.

Bagot is one of the 14 hundreds that were proclaimed on 14 September 1871 by the Governor of South Australia in the County of Palmerston[3] (although the map below shows 20 hundreds).

It is believed to be named after John Tuthill Bagot, who was the Chief Secretary in the Strangways ministry of the Government of South Australia from 1868 to 1870.

[4] The Hundred was enlarged in 1963 when the Governor-General of Australia, William Sidney, 1st Viscount De L'Isle, revoked the Hundred of Sanderson, formerly located to the north of Bagot, and included this into Bagot.

[5] Old maps of Darwin (formerly Palmerston) mention the Hundred of Bagot.
