The Battle of Orewin Bridge (also known as the Battle of Irfon Bridge) was fought between English (led by the Marcher Lords) and Welsh armies on 11 December 1282 near Builth Wells in mid-Wales. It was a decisive defeat for the Welsh because their leader, Llywelyn ap Gruffudd was killed, and this effectively ended the autonomy of Wales.
