The United Nations Security Council (UNSC) is one of the principal organs of the United Nations and is charged with the maintenance of international peace and security. Its powers, outlined in the United Nations Charter, include the establishment of peacekeeping operations, the establishment of international sanctions, and the authorization of military action. Its powers are exercised through United Nations Security Council resolutions.

The Security Council held its first session on 17 January 1946 at Church House, Westminster, London. Since its first meeting, the Council, which exists in continuous session, has travelled widely, holding meetings in many cities, such as Paris and Addis Ababa, as well as at its current permanent home at the United Nations Headquarters in New York City.

There are 15 members of the Security Council, consisting of five veto-wielding permanent members—China, France, Russia, the United Kingdom, and the United States—based on the great powers that were the victors of World War II, and 10 elected non-permanent members with two-year terms. This basic structure is set out in Chapter V of the UN Charter. Security Council members must always be present at UN headquarters in New York so that the Security Council can meet at any time. This requirement of the United Nations Charter was adopted to address a weakness of the League of Nations since that organization was often unable to respond quickly to a crisis.

Angelina Jolie ( /dʒoʊˈliː/ joh-LEE, born Angelina Jolie Voight; June 4, 1975) is an American actress and director. She has received an Academy Award, two Screen Actors Guild Awards, and three Golden Globe Awards, and was named Hollywood's highest-paid actress by Forbes in 2009 and 2011. Jolie promotes humanitarian causes, and is noted for her work with refugees as a Special Envoy and former Goodwill Ambassador for the United Nations High Commissioner for Refugees (UNHCR). She has been cited as the world's "most beautiful" woman, a title for which she has received substantial media attention.

Jolie made her screen debut as a child alongside her father Jon Voight in Lookin' to Get Out (1982), but her film career began in earnest a decade later with the low-budget production Cyborg 2 (1993). Her first leading role in a major film was in the cyber-thriller Hackers (1995). She starred in the critically acclaimed biographical television films George Wallace (1997) and Gia (1998), and won an Academy Award for Best Supporting Actress for her performance in the drama Girl, Interrupted (1999).

Ban Ki-moon (Hangul: 반기문; Hanja: 潘基文; born 13 June 1944) is the eighth and current Secretary-General of the United Nations, after succeeding Kofi Annan in 2007. Before going on to be Secretary-General, Ban was a career diplomat in South Korea's Ministry of Foreign Affairs and in the United Nations. He entered diplomatic service the year he graduated from university, accepting his first post in New Delhi, India. In the foreign ministry he established a reputation for modesty and competence .

Ban was the Foreign Minister of the Republic of Korea from January 2004 to November 2006. In February 2006, he began to campaign for the office of Secretary-General. Ban was initially considered to be a long shot for the office. As foreign minister of South Korea, however, he was able to travel to all of the countries that were members of the United Nations Security Council, a maneuver that turned him into the front runner.

On 11 October 2006, he was elected to be the eighth Secretary-General by the United Nations General Assembly and officially succeeded Annan on 1 January 2007. Ban has led several major reforms regarding peacekeeping and UN employment practices. Diplomatically, Ban has taken particularly strong views on Darfur, where he helped persuade Sudanese President Omar al-Bashir to allow peacekeeping troops to enter Sudan; and on global warming, pressing the issue repeatedly with former U.S. President George W. Bush. Ban has received strong criticism from OIOS, the UN internal audit unit, stating that the secretariat, under Ban's leadership, is "drifting into irrelevance".
