The Peerage of Ireland consists of those titles of nobility created by the English monarchs in their capacity as Lord or King of Ireland, or later by monarchs of the United Kingdom of Great Britain and Ireland. It is one of the five divisions of Peerages in the United Kingdom. The creation of such titles came to an end in the 19th century. The ranks of the Irish peerage are duke, marquess, earl, viscount and baron. As of 2016, there were 135 titles in the Peerage of Ireland extant: two dukedoms, ten marquessates, 43 earldoms, 28 viscountcies, and 52 baronies. However, these titles have no official recognition in the Republic of Ireland, with Article 40.2 of the Constitution of Ireland forbidding the state conferring titles of nobility and stating that an Irish citizen may not accept titles of nobility or honour except with the prior approval of the Irish government.

Robert Clive, 1st Baron Clive,, also known as Clive of India, was the first British Governor of the Bengal Presidency. Clive has been widely credited for laying the foundation of the British East India Company (EIC) rule in Bengal. He began as a writer for the EIC in 1744 and established Company rule in Bengal by winning the Battle of Plassey in 1757. In return for supporting the Nawab Mir Jafar as ruler of Bengal, Clive was guaranteed a jagir of £30,000 per year which was the rent the EIC would otherwise pay to the Nawab for their tax-farming concession. When Clive left India in January 1767 he had a fortune of £180,000 which he remitted through the Dutch East India Company.
