JAMES HAMILTON, 1st earl (1475?-1529), son of James, 1st Lord Hamilton, and of Mary, daughter of James II. of Scotland, succeeded to his father's titles and estates in In he negotiated the marriage of James IV. with Mary Tudor, and was created earl of Arran. Arran was intercepted in England on his way home from a mission to France in 1507 and was imprisoned for a short time. In 1513 he was entrusted with the command of a naval expedition against England, but failed lamentably. On his return he found his rival Angus married to the queen dowager and supreme at court, and joined the party of Albany, and was presi dent of the council of regency from 1517 to 1520. In the feuds of these years Arran supported now one party, now another. The most spectacular encounter was in 1520 when the fierce fight be tween the Hamiltons and the Douglases known as "Cleanse the Causeway" took place in the streets of Edinburgh in 152o. On the proscription of Angus and the Douglases (1528) Arran joined the king at Stirling. He died in 1529.
