Urg the Unclean was a goblin activist who led the 18th century Goblin Rebellions. At some point in his life, he was publicly dunked in a village pond by a group of young wizards, and it is possible that this act triggered one of the rebellions. For his role in the Goblin Rebellions, he was featured on one Chocolate Frog Card.
When Ron Weasley sat his fourth year History of Magic final, he forgot some of the names of the goblin rebels, and thus invented a few as cover, stating that this was easy because "they're all called stuff like Bodrod the Bearded and Urg the Unclean."
