Richard Grenville-Temple, 2nd Earl Temple,, was a British politician. He is best known for his association with his brother-in-law William Pitt with whom he served in government during Britain's participation in the Seven Years War between 1756 and 1761. He resigned, along with Pitt, in protest at the cabinet's failure to declare war on Spain.

The First Lord of the Admiralty, or formally the Office of the First Lord of the Admiralty, was the political head of the English and later British Royal Navy. He was the government's senior adviser on all naval affairs, responsible for the direction and control of the Admiralty, and also of general administration of the Naval Service of the Kingdom of England, Great Britain in the 18th century, and then the United Kingdom, including the Royal Navy, the Royal Marines, and other services. It was one of the earliest known permanent government posts. Apart from being the political head of the Naval Service the post holder was simultaneously the pre-eminent member of the Board of Admiralty. The office of First Lord of the Admiralty existed from 1628 until it was abolished when the Admiralty, Air Ministry, Ministry of Defence and War Office were all merged to form the new Ministry of Defence in 1964. Its modern-day equivalent is the Secretary of State for Defence.
