Peace is a state of harmony in the absence of hostility and violence. In a societal sense, peace is commonly used to mean a lack of conflict (such as war) and freedom from fear of violence between individuals or groups.
Promotion of peace is a core tenet of many philosophies, religions, and ideologies, many of which consider it a core tenet of their philosophy. Some examples are: religions such as Buddhism and Christianity, important figures like Gandhi, and throughout literature like "Perpetual Peace: A Philosophical Sketch" by Immanuel Kant, "The Art of Peace" by Morihei Ueshiba, or ideologies that strictly adhere to it such as Pacifism within a sociopolitical scope. It is a frequent subject of symbolism and features prominently in art and other cultural traditions.
