William Mackenzie, 5th Earl of Seaforth

William Mackenzie, 5th Earl of Seaforth, was a prominent Scottish Highland nobleman and a leading supporter of the Jacobite cause.

As chief of Clan Mackenzie, he commanded significant influence throughout the northern Highlands and played an important role in mobilizing supporters for the Stuart restoration.

During the Jacobite Rising of 1715, Seaforth raised a substantial Highland force and joined the campaign led by John Erskine, Earl of Mar.

He participated in the Battle of Sheriffmuir and was appointed to a senior Jacobite military command in northern Scotland.

Following the failure of the rebellion, Seaforth was declared a traitor by the government, and his estates were forfeited.

His commitment to the Stuart cause continued. In 1719, he participated in another Jacobite expedition supported by Spain and was wounded at the Battle of Glenshiel.

Although he eventually received a royal pardon, his involvement in the Jacobite rebellions remained a defining chapter of his life.
