“Jus gladii” is a Latin term that means “right of the sword” in English. It refers to the legal or political authority that allows the use of force or violence, usually held by a government or ruling authority. Essentially, it denotes the right to use military force or violence to maintain control or assert authority. This concept is historically significant in the context of monarchies and feudal systems, where the ruler had the ultimate power to enforce their will through the use of force.
