For the 17th century Cromwellian regime see Rule of the Major-Generals

Major General or Major-General is a military rank used in many countries. It is derived from the older rank of Sergeant Major General. A Major General is a high-ranking officer normally subordinate to a Lieutenant General and senior to a Brigadier General. In countries that do not maintain the rank of Brigadier General, including much of Eastern Europe, Major General normally serves as the lowest General Officer rank.
