His stepson Tiberius had conquered Pannonia, Dalmatia, Raetia, and temporarily Germania for the Empire, and was thus a prime candidate. In 6 BC, Augustus granted some of his powers to his stepson,[23] and soon after he recognized Tiberius as his heir. In 13 AD, a law was passed which extended Augustus' powers over the provinces to Tiberius,[24] so that Tiberius' legal powers were equivalent to, and independent from, those of Augustus.[24]
