Robert the Bruce married Elizabeth de Burgh, daughter of the Earl of Ulster, in 1302. This marriage was politically important, strengthening Bruce's alliances in Ireland and Scotland. It helped secure support for his cause among the Anglo-Norman and Gaelic lords.

The marriage of Robert the Bruce is celebrated in Scottish chronicle poetry as part of the romantic and heroic narrative of his life. It appears in Barbour's 'The Bruce' and later in ballads, where Elizabeth is often idealized as a supportive queen. The event contributed to the development of the romantic and national epic tradition in Scotland.
