Little was done to plan or secure Tiberius's succession. The Julians and their supporters were diminished in numbers and political influence, thanks to Sejanus, and Tiberius's immediate heirs were dead. Caligula, the sole surviving son of Germanicus, or Tiberius's own grandson, Tiberius Gemellus, were possibly candidates. However, Tiberius only made a half-hearted attempt at the end of his life to make Caligula a quaestor, and thus give him some credibility as a possible successor, while Gemellus himself was still only a teenager and thus completely unsuitable for some years to come.
