Definition: Archimperialism refers to a medieval style of governance that glorified militarism, often involving grandiose courtly extravagance and excessive power in the service of state. It was prevalent under the rule of Charles V of Spain in the 15th century, which is why it's called 'arch' imperial - emphasizing the king's "riches" or "power." The term connotes a type of governance that prioritized military expansion over social justice and common prosperity, often with excessive reliance on soldiers for defense.
