# William Hamilton, Duke of Hamilton

William Douglas-Hamilton, Duke of Hamilton (24 December 1634 – 18 April 1694), also known as Lord William Douglas and the Earl of Selkirk, was a Scottish nobleman and politician. He was the eldest son of the 1st Marquess of Douglas by his second wife, Lady Mary Gordon, a daughter of the 1st Marquess of Huntly.
Subsequent to marrying Anne Hamilton, 3rd Duchess of Hamilton, he was created Duke of Hamilton in the Peerage of Scotland, which also allowed him to use his wife's subsidiary titles during his lifetime and to take the name Hamilton for their descendants.

## Early life and marriage

Lord William Douglas was created Earl of Selkirk in 1646, at the age of 11. He supported the Royalist cause in the Wars of the Three Kingdoms and was fined £,1000, under the terms of the English Commonwealth's Act of Pardon and Grace to the People of Scotland.
On 29 April 1656, he married Anne Hamilton, Duchess of Hamilton. She was from a staunchly Royalist dynasty. Her estates had been declared forfeit by Oliver Cromwell after the activities of her father and uncle in the Wars of the Three Kingdoms. Her father, James, 1st Duke of Hamilton, was executed by the English in 1649 at the end of the Second English Civil War, and her uncle, William, 2nd Duke of Hamilton, died following the Battle of Worcester in 1651.

## Restoration

After the Restoration, he was created Duke of Hamilton in 1660 on the petition of his wife, Anne Hamilton, suo jure Duchess of Hamilton, receiving also several of the other Hamilton peerages for life.
He supported the Duke of Lauderdale in the early stages of his Scottish policy, in which he adopted a moderate attitude towards the Presbyterians. However, the two were soon alienated through the influence of the Countess of Dysart, according to Gilbert Burnet, who spent much time at Hamilton Palace in arranging the Hamilton family's archives. With other Scottish noblemen who resisted Lauderdale's measures, he was twice summoned to London to present his case at court, but without obtaining any result.
He was dismissed from the Privy Council in 1676, and on a subsequent visit to London, Charles II refused to receive him. On the accession of James II, he received numerous honours, but he was one of the first to enter into communication with William III of Orange.
He presided over the Convention of Edinburgh, summoned at his request, which offered the Scottish crown to William III and Mary II in March 1689. His death took place at Holyrood Palace on 18 April 1694. His wife survived until 17 April 1716.
