Hamilton was born at Hamilton Palace in December 1616, the younger son of James Hamilton, 2nd Marquess of Hamilton and Lady Ann Cunningham.
Hamilton was educated at the University of Glasgow, and from there travelled to The Continent, where he spent time at the court of Louis XIII of France, on his return aged 21 he established himself as a favourite at the court of Charles I in London.
He became Secretary of State for Scotland. On 26 September 1647 he signed, on behalf of the Scots, the treaty with Charles known as the "Engagement", at Carisbrooke Castle, and helped to organise the Second English Civil War. In 1648 he fled to Holland to the court in exile of the Prince of Wales at The Hague.
The following year he succeeded to the Dukedom of Hamilton, the Marquisate of Hamilton, the Earldoms of Arran and Cambridge and Lordhips of Aven and Innerdale following his brother"s execution, making him the most senior figure among the Scots Royalist exiles.
He returned to Scotland with King Charles II in 1650, but, finding a reconciliation with the Marquess of Argyll impossible, he refused to prejudice Charles"s cause by pushing his claims. He retired to his estates on the Isle of Arran until the Scottish invasion of England during the Third English Civil War, when he acted as colonel of a regiment drawn mainly from his tenantry.
He died from the effects of wounds received at the Battle of Worcester, at The Commandery, Charles II"s headquarters in that city. A neighbouring street, Hamilton Road, is named in his honour.
Hamilton married Lady Elizabeth Maxwell, daughter to James Maxwell, 1st Earl of Dirletoun on 26 May 1638, and had issue:
James Hamilton, Lord Polmont (died in infancy, buried at Westminster Abbey)
Lady Anne Hamilton, married Robert Carnegie, 3rd Earl of Southesk
Lady Elizabeth Hamilton, married 1st Lord Kilmaurs, 2nd Sir David Cunningham of Robertland
Lady Mary Hamilton, married 1st Alexander Livingston, 2nd Earl of Callendar, 2nd Sir James Livingstone of Westquarter, 3rd James Ogilvy, 3rd Earl of Findlater
Lady Margaret Hamilton, married William Blair of that ilk.
Lady Diana Hamilton, (died in infancy)
Leaving four daughters but no male heirs, according to the remainder, the dukedom of Hamilton devolved on his eldest surviving niece, Anne, who became Duchess of Hamilton in her own right. A highly fictionalised Hamilton is depicted in Nigel Tranter"s Montrose trilogy.
