Donald of Islay, Lord of the Isles
Donald of Islay was a formidable figure in medieval Scottish history, serving as the chief of Clan Donald and the Lord of the Isles. Inheriting a vast maritime empire from his father, John of Islay, Donald governed a territory that centered on the island of Islay but extended across most of the Hebrides and significant portions of the mainland, including Kintyre, Knapdale, Lochaber, Garmoran, and Morvern.
Far from being an isolated regional ruler, Donald was deeply integrated into the Scottish aristocracy. As the grandson of King Robert II and first cousin to King Robert III, he possessed royal blood—a fact he emphasized by incorporating the royal tressure into his coat of arms. His reign was characterized by a complex dance of power, shifting alliances with the English crown, and fierce territorial disputes with the Stewart dynasty.

Early Rule and Internal Strife
Donald's early tenure was marked by internal instability, specifically a revolt led by his younger brother, John Mór. This conflict stemmed from John Mór's dissatisfaction with his limited inheritance in Islay and Kintyre, despite having previously been the tànaiste (heir-apparent) before Donald had a son.
The rebellion, which began in 1387, was supported by the MacKinnons, MacLeans, and MacLeods. The conflict saw the involvement of Niall MacKinnon and the "Green Abbot" of Iona. Donald eventually suppressed the uprising; the MacKinnon chief was executed, and the abbot was imprisoned for life. Although John Mór fled to Ulster—where he became the Lord of Dunyvaig and the Glens—he eventually submitted to Donald and was forgiven.
Expansion and Conflict with the Stewarts
With internal stability restored, Donald looked toward the north and east, where the Stewarts held significant power. Much of this region, including Ross, Skye, and Badenoch, was controlled by Alexander Stewart, the Earl of Buchan, notoriously known as the "Wolf of Badenoch." Alexander served as the "Lieutenant of the North," effectively acting as the crown's representative in the region.
As the Duke of Albany (Robert Stewart) began to strip the "Wolf of Badenoch" of his powers in the late 14th century, Donald and his brother, Alexander of Lochaber, moved to fill the vacuum. By 1395, the MacDonalds had seized Urquhart Castle and established a presence in the Moray lowlands. This expansion eventually brought Donald into direct conflict with the Duke of Albany, who viewed the MacDonalds' growing influence as a threat to the crown's authority.
The Struggle for the Earldom of Ross
The conflict escalated when Donald pressed the claims of his wife, Mariota Leslie, to the Earldom of Ross following the death of Alexander Leslie. By 1411, Donald had seized Dingwall Castle, the earldom's primary seat. To strengthen his position, Donald negotiated an alliance with the captive heir to the Scottish throne, James Stewart, and King Henry IV of England.
In 1411, Donald marched an army of 10,000 Islesmen and Ross vassals against the Earl of Mar, Albany's primary ally. This culminated in the Battle of Harlaw, where Donald achieved a decisive victory. Despite this military success, the political aftermath favored Albany, who eventually retook Dingwall and secured the earldom for his own son, John Stewart, though Donald continued to proclaim himself the "Lord of Ross."
