Dudley Ryder, 1st Earl of Harrowby, PC, FSA was a prominent British politician of the Pittite faction and the Tory party.

Tiverton was a constituency located in Tiverton in east Devon, formerly represented in the House of Commons of the Parliament of the United Kingdom. Enfranchised as a parliamentary borough in 1615 and first represented in 1621, it elected two Members of Parliament (MPs) by the first past the post system of election until 1885. The name was then transferred to a county constituency electing one MP.
