George Montagu, 1st Earl of Halifax (also spelt George Montague) (9 May 1739), of Horton, Northamptonshire, was a British politician who sat in the House of Commons from 1705 to 1715 when he became a peer.
Montagu was the son of Edward Montagu of Horton and his wife Elizabeth Pelham, a daughter of Sir John Pelham, 3rd Baronet. He succeeded his father in 1690, and received the post then of Warden and chief forester of Salcey forest, Northamptonshire, which he held for the rest of his life.
He was educated at Eton College in 1698. From 1701 to 1704, he travelled abroad through Italy, Austria, Holland, Budapest, Belgrade and Constantinople.[1] He was a paternal great-grandson of Henry Montagu, 1st Earl of Manchester.
Montagu was returned unopposed as Member of Parliament for Northampton with the support of Christopher Montagu at the 1705 English general election. He was returned again at the 1708 British general election, the 1710 British general election and at the 1713 British general election. In 1714 he was appointed appointments Auditor of the Exchequer, which he held for the rest of his life.[1]
He was made a Privy Councillor on 27 November 1717, Lord Justice in 1720 and Keeper/Ranger of Bushy Park. He was appointed a Knight, Order of the Bath (K.B.) in 1725.[1]
His family's seat was Horton House, Horton, Northamptonshire which was demolished in 1936.
As Ranger of Bushy Park, Halifax had built (1714–1715) and sometimes inhabited 'Upper Lodge' or 'New Lodge', today a function building of the National Physical Laboratory, on the north-west side of the park in its Teddington part. This was in the first two years of the reign of George II just as he acceded to his titles. The property passed to his son, followed by Lord North, his eldest daughter's son.[2]
George's uncle, Charles Montagu, 1st Earl of Halifax, a childless widower, ensured his titles would pass to George (being the eldest son of his eldest brother), and gave him most of his estate. George succeeded his uncle as second Baron Halifax under its special remainder.[3]
A few weeks after succeeding, George was created Earl of Halifax and Viscount Sunbury, reviving the other titles which had been created the previous year for his uncle. Two years later he was sworn of Privy Council.[1]
Montagu was twice married. On 8 April 1706, he married Ricarda Posthuma Saltonstall (–1711). Before her death in 1711, they were the parents of one daughter:
On about 28 June 1712, Montagu married Lady Mary Lumley (1690–1726), a daughter of Richard Lumley, 1st Earl of Scarborough.[4] Together they had at least seven children, including:
George Montagu died in 1739 and was succeeded in the titles by his son George.
Through his eldest child Lucy, he was a grandfather of Frederick North, Lord North, who served as the Prime Minister of Great Britain from 1770 to 1782.
