A commander-in-chief is the person who exercises supreme command and control of a nation's military forces. In many nations, this role is typically vested in the head of state, such as a monarch or a president, or may be vested in the head of government, often the prime minister. The term originates from the Latin commander and in chief, meaning the highest or principal leader. In Hebrew, the term is translated as מפקד העליון (Mefaked Ha'Elyon). In French, it is commandant en chef, and in German, it is Oberbefehlshaber. The commander-in-chief is responsible for the strategic direction and overall management of the armed forces, though day-to-day operations may be delegated to subordinate commanders. The role often comes with significant constitutional and legal authority, ensuring the civilian control of the military. Historically, the position has been pivotal in times of war and peace, shaping national defense policies and military strategies.
