Morale is the capacity of a group's members to maintain belief in an institution or goal, particularly in the face of opposition or hardship. Morale is often referenced by authority figures as a generic value judgment of the willpower, obedience, and self-discipline of a group tasked with performing duties assigned by a superior. According to Alexander H. Leighton, "morale is the capacity of a group of people to pull together persistently and consistently in pursuit of a common purpose". With good morale, a force will be less likely to give up or surrender. Deliberately attempting to reduce another group's morale is called demoralization. Morale is usually assessed at a collective, rather than an individual level. In wartime, civilian morale is also important.
