Matthew Stewart, 4th Earl of Lennox

1516 — September 4, 1571 — Dumbarton, Scotland

Matthew Stewart, 4th Earl of Lennox, was a Scottish nobleman and politician who rose to become Regent of Scotland during one of the most turbulent periods in the kingdom's history. A leader among the Catholic nobility, he was closely tied to the English and Scottish royal houses through marriage and blood, and he ultimately became the paternal grandfather of King James VI of Scotland, who later united the crowns of Scotland and England as James I. His life was marked by exile, shifting political alliances, and a violent death that underscored the deep factionalism of 16th-century Scotland.

Early Life and Exile

Matthew Stewart was born in 1516, likely at Dumbarton Castle, into one of Scotland's most powerful noble families. He inherited the earldom of Lennox as a young man following the death of his father, John Stewart, 3rd Earl of Lennox, who was killed at the Battle of Linlithgow Bridge in 1526 amid the fierce rivalry between the Hamilton and Stewart-Lennox factions. Because of the ongoing feud with the Hamiltons, who held significant influence over the young King James V, Lennox spent much of his youth in France, where he was raised in relative safety and absorbed the courtly and military customs of the French nobility. This period abroad shaped him into a sophisticated and ambitious figure with international connections. He returned to Scotland in 1543 following the death of James V, hoping to secure political power during the regency crisis that followed, but his ambitions quickly entangled him in the volatile struggle between pro-French and pro-English factions vying for control of the infant Mary, Queen of Scots.

Political Career and Marriage

Failing to gain the influence he sought in Scotland, Lennox allied himself with King Henry VIII of England, a decision that led to his exile in England for nearly three decades. In 1544, he married Lady Margaret Douglas, a niece of Henry VIII and daughter of Margaret Tudor, thereby linking his family directly to the English royal line. The couple settled at Temple Newsam in Yorkshire, a grand estate that became their primary residence during their long years away from Scotland. Their son, Henry Stuart, Lord Darnley, was born in 1545 and later married Mary, Queen of Scots, in 1565, making Lennox the father-in-law of the Scottish queen and positioning his family at the very center of Scottish and English dynastic politics. Lennox remained a committed Catholic and a firm supporter of the Stuart claim to both thrones, using his English connections to advocate for his family's interests even as Scotland's Reformation transformed the religious and political landscape of his homeland.

Regency and Death

After Darnley's murder in 1567 and the subsequent fall of Mary, Queen of Scots, Lennox returned to Scotland to champion the cause of his infant grandson, King James VI. Amid the civil conflict between supporters of the deposed queen and those of the young king, Lennox was appointed Regent of Scotland in 1570, following the assassination of the previous regent, the Earl of Moray. As regent, he worked to consolidate royal authority and suppress the remaining Marian faction, but the kingdom remained bitterly divided. On September 4, 1571, Lennox was killed during a raid on Stirling by supporters of Mary, Queen of Scots, becoming one of several Scottish regents to die violently during this era of factional warfare. His death left a lasting legacy nonetheless, for his grandson James VI would go on to inherit the English throne in 1603, uniting the two kingdoms and founding the Stuart dynasty that Lennox had fought so fiercely to protect.
