The Secretary-General of the United Nations is the head of the Secretariat of the United Nations, one of the principal organs of the United Nations. The Secretary-General also acts as the de facto spokesperson and leader of the United Nations.

The current Secretary-General is Ban Ki-moon of South Korea, who took office on 1 January 2007. His first term expired on 31 December 2011. He was re-elected, unopposed, to a second term on 21 June 2011.

The Secretary-General was envisioned by US President Franklin D. Roosevelt as a "world moderator," but the vague definition provided by the UN Charter left much room for interpretation by those who would later inhabit the position. According to the U.N. website his roles are further defined as "diplomat and advocate, civil servant and CEO." Nevertheless, this more abstract description has not prevented the office holders from speaking out and playing important roles on global issues to various degrees. Article 97 of the UN Charter states that the Secretary-General shall be the "chief administrative officer" of the Organization, but does not dictate his specific obligations.

Secretary General is a title many different organizations give to their leader.

The Syrian uprising is an ongoing, violent internal conflict in Syria. It is part of the wider Arab Spring, a wave of upheaval throughout the Arab world. Public demonstrations across Syria began on 26 January 2011 and developed into a nationwide uprising. Protesters demanded the resignation of President Bashar al-Assad, the overthrow of his government, and an end to nearly five decades of Ba’ath Party rule.

Since spring 2011, the Syrian government has deployed the Syrian Army to quell the uprising. Several cities have been besieged, but nevertheless the unrest continues. According to witnesses, soldiers who refused to open fire on civilians were summarily executed by the Syrian Army. The Syrian government denied reports of defections, and blamed "armed gangs" for causing trouble. Since early autumn 2011, civilians and army defectors began forming fighting units, which began an insurgency campaign against the Syrian Army. The insurgents unified under the banner of the Free Syrian Army and fought in an increasingly organized fashion; however, the civilian component of the armed opposition lacks an organized leadership.

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".
