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 and freedom from fear of violence between individuals or groups.

Promotion of peace is a core tenet of many philosophies, religions, and ideologies. Some examples are: religions such as Buddhism, Christianity, Jainism, and Islam, important figures like Mahatma Gandhi and Martin Luther King Jr., and literary writings 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.

The representation of peace has taken many diverse shapes and symbols based on culture, context, and history, each with their respective symbolism whose nature can be very complex. An example, being during post-violence, in contexts where intense emotions, these symbols can form to evoke unity and cooperation, described as to fill groups of people with pride and connection, yet the symbolism could also possibly form to convey oppression, hatred, or else. As such, a universal definition for peace does not concretely exist but gets expanded and defined proactively based on context and culture, in which it can serve many meanings not particularly benevolent in its symbolism.

"Psychological peace" (such as peaceful thinking and emotions) is less relatively well-defined, yet perhaps a necessary precursor to establishing "behavioural peace". Peaceful behaviour sometimes results from a "peaceful inner disposition". It has been argued by some that inner qualities such as tranquility, patience, respect, compassion, kindness, self-control, courage, moderation, forgiveness, equanimity, and the ability to see the big picture can promote peace within an individual, regardless of the external circumstances of their life.

Etymology

The term 'peace' originates from the Anglo-French , and the Old French , meaning "peace, reconciliation, silence, agreement" (11th century). itself comes from the Latin , meaning "peace, compact, agreement, treaty of peace, tranquility, absence of hostility, harmony."

The English word came into use in various personal greetings from as a translation of the Hebrew word , which, according to Jewish theology, comes from a Hebrew verb meaning 'to be complete, whole'. Although "peace" is the usual translation, , which is also cognate with the Arabic word , has multiple other meanings, including justice, good health, safety, well-being, prosperity, equity, security, good fortune, and friendliness, as well as "hello" and "goodbye".

On a personal level, peaceful behaviours are kind, considerate, respectful, just, and tolerant of others' beliefs and behaviors. This understanding of peace can also pertain to an individual's introspective sense or concept of themselves, as in being "at peace" in one's own mind, as found in European references from . The early English term is also used in the sense of "quiet", reflecting calm, serene, and meditative approaches to family or group relationships that have an absence of quarreling, disturbances and agitation.

In many languages, the word 'peace' is also used as a greeting or a farewell, for example the Hawaiian word , as well as the Arabic word . In English the word peace is occasionally used as a farewell, especially for the dead, as in the phrases "rest in peace" or "peace out".

History

Peace was forged through diplomacy in the form of royal marriages, both in the distant past and in modern times. Two early examples of royal marriages being used to establish diplomatic relations are Hermodike I, who married the king of Phrygia around 800 BCE, and Hermodike II, who married the king of Lydia around 600 BCE. Both marriages involved Greek princesses from the house of Agamemnon and kings from what is now Turkey. The marriages between the Greek princesses and the kings of Phrygia and Lydia had a significant impact on the region, leading to the transfer of important technological innovations from Anatolia to Greece. In particular, the Phrygians introduced the Greek alphabet, while the Lydians pioneered the use of coinage as a form of currency. Both inventions were rapidly adopted by surrounding nations through further trade and cooperation.

Peace has not always been achieved through peaceful means; in many cases, it has been enforced by the victors of war, often through the use of violence and coercion. In his work Agricola, the Roman historian Tacitus writes about the greed and arrogance of the Roman Empire, portraying it as a ruthless and self-serving power. One quote, which Tacitus says is from the Caledonian chieftain Calgacus, ends with: "" ("To ravage, to slaughter, to usurp under false titles, they call empire; and where they make a desert, they call it peace." —Oxford Revised Translation).

Discussion of peace is therefore at the same time an inquiry into its form. Societal peace can be seen at least in two forms: A simple silence of arms, absence of war. Absence of war accompanied by particular requirements for the mutual settlement of relations, which are characterized by justice, mutual respect, respect for law, and good will.

Since 1945, the United Nations and the United Nations Security Council have operated under the aim to resolve conflicts without war. Nonetheless, nations have entered numerous military conflicts since then.

Organizations and prizes

United Nations

The United Nations (UN) is an international organization whose stated aims are to facilitate cooperation in international law, international security, economic development, social progress, human rights, and achieving world peace. The UN was founded in 1945 after World War II to replace the League of Nations, to stop wars between countries, and to provide a platform for dialogue.

After authorization by the Security Council, the UN sends peacekeepers to regions where armed conflict has recently ceased or paused to enforce the terms of peace agreements and to discourage combatants from resuming hostilities. Since the UN does not maintain its own military, peacekeeping forces are voluntarily provided by member states of the UN. The forces who enforce UN accords, also called the "Blue Helmets", are awarded United Nations Medals, which are considered international decorations instead of military decorations. The peacekeeping force as a whole received the Nobel Peace Prize in 1988.

Police

The obligation of the state to provide for domestic peace within its borders is usually charged to the police and other general domestic policing activities. The police are a constituted body of persons empowered by a state to enforce the law, to protect the lives, liberty and possessions of citizens, and to prevent crime and civil disorder. Their powers include the power of arrest and the legitimized use of force. The term is most commonly associated with the police forces of a sovereign state that are authorized to exercise the police power of that state within a defined legal or territorial area of responsibility. Police forces are often defined as being separate from the military and other organizations involved in the defense of the state against foreign aggressors; however, gendarmerie are military units charged with civil policing. Police forces are usually public sector services, funded through taxes.

National security

The national security apparatus of a nation is responsible for providing peace and security against foreign threats and aggression. National security can be threatened by a range of factors, including actions by other states (such as military or cyber attacks), violent non-state actors (such as terrorist attacks), organized criminal groups (such as drug cartels), and natural disasters (such as floods and earthquakes). Systemic drivers of insecurity, which may be transnational, include economic inequality and marginalisation, political exclusion, climate change, and nuclear proliferation. The preservation of peace and the security of a nation state has several dimensions, including economic security, energy security, physical security, environmental security, food security, border security, and cyber security. These dimensions correlate closely with elements of national power.

League of Nations

The principal forerunner of the United Nations was the League of Nations. It was created at the Paris Peace Conference of 1919, and emerged from the advocacy of Woodrow Wilson and other idealists during World War I. The Covenant of the League of Nations was included in the Treaty of Versailles in 1919, and the League was based in Geneva until its dissolution as a result of World War II and replacement by the United Nations. The high hopes widely held for the League in the 1920s, for example amongst members of the League of Nations Union, gave way to widespread disillusion in the 1930s as the League struggled to respond to challenges from Nazi Germany, Fascist Italy, and Japan.

The prominent scholar Alfred Eckhard Zimmern, who is widely regarded as one of the most influential intellectuals of the League of Nations, drew inspiration for his studies from the classics, along with other British scholars such as Gilbert Murray and Florence Stawell. This group of scholars is often referred to as the "Greece and peace" set, due to their shared interest in ancient Greek civilization and the promotion of peace.

The creation of the League of Nations, and the hope for informed public opinion on international issues (expressed for example by the Union for Democratic Control during World War I), also led to the creation after World War I of bodies dedicated to understanding international affairs, such as the Council on Foreign Relations in New York and the Royal Institute of International Affairs at Chatham House in London. At the same time, the academic study of international relations started to professionalise, with the first professorship of international politics created in 1919 at Aberystwyth University in Wales, named after Woodrow Wilson.

Olympic Games

The late 19th century idealist advocacy of peace which led to the creation of the Nobel Peace Prize, the Rhodes Scholarships, the Carnegie Endowment for International Peace, and ultimately the League of Nations, also saw the re-emergence of the ancient Olympic ideal. Led by Pierre de Coubertin, this culminated in the holding in 1896 of the first of the modern Olympic Games.

Nobel Peace Prize

Since 1901, the Nobel Peace Prize has been the world's most prestigious honor given to individuals or organizations who have made significant contributions to peace. The prize is awarded by the Norwegian Nobel Committee, a group of five individuals chosen by the Norwegian parliament. Nominees for the prize come from around the world, and are often those who have worked to end conflict, protect human rights, or promote humanitarian efforts. It is awarded annually to internationally notable persons following the prize's creation in the will of Alfred Nobel. According to Nobel's will, the Peace Prize shall be awarded to the person who "...shall have done the most or the best work for fraternity between nations, for the abolition or reduction of standing armies, and for the holding and promotion of peace congresses."
