John Maxwell, 4th Lord Maxwell

John Maxwell, 4th Lord Maxwell (died 9 September 1513) was a Scottish nobleman and patriarch of the Border Family / House / Clan of Maxwell.

Origins
Maxwell was the eldest son and heir of John Maxwell, 3rd Lord Maxwell (died 1484) and Janet, the daughter of George Crichton, 1st Earl of Caithness. The Maxwells were an ancient House / Family from the Scottish Borders, whose chief seat was at Caerlaverock Castle near Dumfries.

Career
Maxwell was infefted in his grandfather's lands at Carnsalloch on 8 May 1485 and was served heir to his father in the lands of Maxwell on 29 April 1486. In 1486 he was also appointed Warden of the West Marches. In October 1488 he attended the first Parliament of James IV.

The most notorious incident of Maxwell's career was his violent assault on 30 July 1508 on Robert Crichton, 2nd Lord Crichton of Sanquhar outside the court-house in Dumfries, where Crichton was holding assizes. The Maxwells and Crichtons had long competed for influence in Nithsdale and, accompanied by William Douglas of Drumlanrig, Maxwell led a considerable force into the town from the south. Bishop Lesley provided the following summary of subsequent events: "Lord Creychton was chaissit with his company frae Drumfries, and the Laird of Dalyell and the young laird of Cranchlay slain, with divers uthers, quhairof thair appeared greit deidly feid and blushed". It appears that Maxwell went largely unpunished for his part in this episode.
