Almirante-general was the highest rank in the
Portuguese Navy, from 1808 to 1812 and again, from 1892 to 1910. It was the naval equivalent to the rank of
marechal-general ("general field marshal") of the
Portuguese Army. The rank was initially introduced in 1808, to be assigned to the commander-in-chief of the navy. The
almirante-general had similar functions to those of the former
capitão-general da armada (captain general of the navy) which had been extinguished in 1796 and whose functions passed to the Board of the Admiralty. The rank was only given to
Infante Pedro Carlos de Bragança, being extinguished when he died in 1812. In 1892, the
almirante-general rank was reintroduced as a mere ceremonial rank to be held by the King of Portugal in his constitutional function of supreme commander of the navy. As supreme commander of the army, the king also held the ceremonial rank of
marechal-general. The last holder of the rank was King
Manuel II. ==Russia==
