An adjutant general is a military chief administrative officer.
In Revolutionary France, the adjudant-général was a senior staff officer, effectively an assistant to a general officer. It was a special position for lieutenant-colonels and colonels in staff service. Starting in 1795, only colonels could be appointed to the position. It was supplemented by the rank of adjudant-commandant in 1800. In 1803 the position was abolished and adjudants-généraux reverted to the rank of colonel.
In Imperial Russia, the General-Adjutant (Russian: Генерал-адъютант) was an assistant who attended the Tsar, a field marshal or a general.
