Henry Bathurst, 3rd Earl Bathurst, was a High Tory, High Church Pittite. He was an MP for thirty years before ennoblement. A personal friend of William Pitt the Younger, he became a broker of deals across cabinet factions during the Napoleonic era. After the Napoleonic Wars, Bathurst was on the conservative wing of the Tory party.

Cirencester was a parliamentary constituency in Gloucestershire. From 1571 until 1885, it was a parliamentary borough, which returned two Member of Parliament (MPs) to the House of Commons of the Parliament of the United Kingdom until 1868, and one member between 1868 and 1885. In 1885 the borough was abolished but the name was transferred to the county constituency in which it stood; this constituency was abolished for the 1918 general election.
