Tiberius Orestius Caesar Augustus Vandalicus Africanus Britannicus, more commonly known as Tiberius II, was Emperor of the Western Roman Empire from August 12 525 to September 22 556, the second from the Orestian Dynasty. Inheriting a largely territorially restored Empire from his father, Romulus Augustus, Tiberius' initial concerns were with the solidity of the Western Imperial Throne, but they eventually gave way (as his position became more and more secure) to an obsession with reconquest, which culminated in the return to, and complete conquest of, Britannia.
