A larger, stronger breed of Orc first appearing in the late Third Age. Unlike ordinary Orcs, the Uruk-hai can endure sunlight and are as tall as Men, with greater discipline and ferocity. Sauron breeds the first Uruks in Mordor, and Saruman later develops his own strain in Isengard, possibly through crossbreeding Orcs with Men. Saruman's Uruk-hai are responsible for the attack on the Fellowship at Amon Hen and the capture of Merry and Pippin.
