Government of Panama

Explored and settled by the Spanish in the 16th century, Panama broke with Spain in 1821 and joined a union of Colombia, Ecuador, and Venezuela - named the Republic of Gran Colombia. When the latter dissolved in 1830, Panama remained part of Colombia. With US backing, Panama seceded from Colombia in 1903 and promptly signed a treaty with the US allowing for the construction of a canal and US sovereignty over a strip of land on either side of the structure (the Panama Canal Zone). The Panama Canal was built by the US Army Corps of Engineers between 1904 and 1914. In 1977, an agreement was signed for the complete transfer of the Canal from the US to Panama by the end of the century. Certain portions of the Zone and increasing responsibility over the Canal were turned over in the subsequent decades. With US help, dictator Manuel NORIEGA was deposed in 1989. The entire Panama Canal, the area supporting the Canal, and remaining US military bases were transferred to Panama by the end of 1999. An ambitious expansion project to more than double the Canal's capacity - by allowing for more Canal transits and larger ships - was carried out between 2007 and 2016.

Government of Peru

Ancient Peru was the seat of several prominent Andean civilizations, most notably that of the Incas whose empire was captured by Spanish conquistadors in 1533. Peru declared its independence in 1821, and remaining Spanish forces were defeated in 1824. After a dozen years of military rule, Peru returned to democratic leadership in 1980, but experienced economic problems and the growth of a violent insurgency. President Alberto FUJIMORI's election in 1990 ushered in a decade that saw a dramatic turnaround in the economy and significant progress in curtailing guerrilla activity. Nevertheless, the president's increasing reliance on authoritarian measures and an economic slump in the late 1990s generated mounting dissatisfaction with his regime, which led to his resignation in 2000. A caretaker government oversaw a new election in the spring of 2001, which installed Alejandro TOLEDO Manrique as the new head of government - Peru's first democratically elected president of indigenous ethnicity. The presidential election of 2006 saw the return of Alan GARCIA Perez who, after a disappointing presidential term from 1985 to 1990, oversaw a robust economic rebound. Former army officer Ollanta HUMALA Tasso was elected president in June 2011, and carried on the sound, market-oriented economic policies of the three preceding administrations. Poverty and unemployment levels have fallen dramatically in the last decade, and today Peru boasts one of the best performing economies in Latin America. Pedro Pablo KUCZYNSKI Godard won a very narrow presidential runoff election in June 2016.

Government of Philippines

The Philippine Islands became a Spanish colony during the 16th century; they were ceded to the US in 1898 following the Spanish-American War. In 1935 the Philippines became a self-governing commonwealth. Manuel QUEZON was elected president and was tasked with preparing the country for independence after a 10-year transition. In 1942 the islands fell under Japanese occupation during World War II, and US forces and Filipinos fought together during 1944-45 to regain control. On 4 July 1946 the Republic of the Philippines attained its independence. A 20-year rule by Ferdinand MARCOS ended in 1986, when a "people power" movement in Manila ("EDSA 1") forced him into exile and installed Corazon AQUINO as president. Her presidency was hampered by several coup attempts that prevented a return to full political stability and economic development. Fidel RAMOS was elected president in 1992. His administration was marked by increased stability and by progress on economic reforms. In 1992, the US closed its last military bases on the islands. Joseph ESTRADA was elected president in 1998. He was succeeded by his vice-president, Gloria MACAPAGAL-ARROYO, in January 2001 after ESTRADA's stormy impeachment trial on corruption charges broke down and another "people power" movement ("EDSA 2") demanded his resignation. MACAPAGAL-ARROYO was elected to a six-year term as president in May 2004. Her presidency was marred by several corruption allegations but the Philippine economy was one of the few to avoid contraction following the 2008 global financial crisis, expanding each year of her administration. Benigno AQUINO III was elected to a six-year term as president in May 2010 and was succeeded by Rodrigo DUTERTE in May 2016.


The Philippine Government faces threats from several groups, some of which are on the US Government's Foreign Terrorist Organization list. Manila has waged a decades-long struggle against ethnic Moro insurgencies in the southern Philippines, which has led to a peace accord with the Moro National Liberation Front and ongoing peace talks with the Moro Islamic Liberation Front. The decades-long Maoist-inspired New People's Army insurgency also operates through much of the country. The Philippines faces increased tension with China over disputed territorial and maritime claims in the South China Sea.

Government of Puerto Rico

Populated for centuries by aboriginal peoples, the island was claimed by the Spanish Crown in 1493 following Christopher COLUMBUS' second voyage to the Americas. In 1898, after 400 years of colonial rule that saw the indigenous population nearly exterminated and African slave labor introduced, Puerto Rico was ceded to the US as a result of the Spanish-American War. Puerto Ricans were granted US citizenship in 1917. Popularly elected governors have served since 1948. In 1952, a constitution was enacted providing for internal self-government. In plebiscites held in 1967, 1993, and 1998, voters chose not to alter the existing political status with the US, but the results of a 2012 vote left open the possibility of American statehood. Economic recession on the island has led to a net population loss since about 2005, as large numbers of residents moved to the US mainland. The trend has accelerated since 2010; in 2014, Puerto Rico experienced a net population loss to the mainland of 64,000, more than double the net loss of 26,000 in 2010.

Government of Republic of Liberia

Settlement of freed slaves from the US in what is today Liberia began in 1822; by 1847, the Americo-Liberians were able to establish a republic. William TUBMAN, president from 1944-71, did much to promote foreign investment and to bridge the economic, social, and political gaps between the descendants of the original settlers and the inhabitants of the interior. In 1980, a military coup led by Samuel DOE ushered in a decade of authoritarian rule. In December 1989, Charles TAYLOR launched a rebellion against DOE's regime that led to a prolonged civil war in which DOE was killed. A period of relative peace in 1997 allowed for an election that brought TAYLOR to power, but major fighting resumed in 2000. An August 2003 peace agreement ended the war and prompted the resignation of former president Charles TAYLOR, who was convicted by the UN-backed Special Court for Sierra Leone in The Hague for his involvement in Sierra Leone's civil war. After two years of rule by a transitional government, democratic elections in late 2005 brought President Ellen JOHNSON SIRLEAF to power. She subsequently won reelection in 2011 and remains challenged to rebuild Liberia's economy, particularly following the 2014-15 Ebola epidemic, and to reconcile a nation still recovering from 14 years of fighting. The UN Security Council in September 2015 passed Resolution 2239, which renewed the mandate for the UN Mission in Liberia for another year. In July 2016, the UN handed over peacekeeping responsibility to Liberia and reduced the UN troop presence, which now serves a support role.

Government of Russia

Founded in the 12th century, the Principality of Muscovy was able to emerge from over 200 years of Mongol domination (13th-15th centuries) and to gradually conquer and absorb surrounding principalities. In the early 17th century, a new ROMANOV Dynasty continued this policy of expansion across Siberia to the Pacific. Under PETER I (ruled 1682-1725), hegemony was extended to the Baltic Sea and the country was renamed the Russian Empire. During the 19th century, more territorial acquisitions were made in Europe and Asia. Defeat in the Russo-Japanese War of 1904-05 contributed to the Revolution of 1905, which resulted in the formation of a parliament and other reforms. Repeated devastating defeats of the Russian army in World War I led to widespread rioting in the major cities of the Russian Empire and to the overthrow in 1917 of the imperial household. The communists under Vladimir LENIN seized power soon after and formed the USSR. The brutal rule of Iosif STALIN (1928-53) strengthened communist rule and Russian dominance of the Soviet Union at a cost of tens of millions of lives. After defeating Germany in World War II as part of an alliance with the US (1939-1945), the USSR expanded its territory and influence in Eastern Europe and emerged as a global power. The USSR was the principal adversary of the US during the Cold War (1947-1991). The Soviet economy and society stagnated in the decades following Stalin’s rule, until General Secretary Mikhail GORBACHEV (1985-91) introduced glasnost (openness) and perestroika (restructuring) in an attempt to modernize communism, but his initiatives inadvertently released forces that by December 1991 splintered the USSR into Russia and 14 other independent republics.

Following economic and political turmoil during President Boris YELTSIN's term (1991-99), Russia shifted toward a centralized authoritarian state under the leadership of President Vladimir PUTIN (2000-2008, 2012-present) in which the regime seeks to legitimize its rule through managed elections, populist appeals, a foreign policy focused on enhancing the country's geopolitical influence, and commodity-based economic growth. Russia faces a largely subdued rebel movement in Chechnya and some other surrounding regions, although violence still occurs throughout the North Caucasus.

Government of Saint Helena, Ascension and Tristan da Cunha

Saint Helena is a British Overseas Territory consisting of Saint Helena and Ascension Islands, and the island group of Tristan da Cunha.


Saint Helena: Uninhabited when first discovered by the Portuguese in 1502, Saint Helena was garrisoned by the British during the 17th century. It acquired fame as the place of Napoleon BONAPARTE's exile from 1815 until his death in 1821, but its importance as a port of call declined after the opening of the Suez Canal in 1869. During the Anglo-Boer War in South Africa, several thousand Boer prisoners were confined on the island between 1900 and 1903.


Ascension Island: This barren and uninhabited island was discovered and named by the Portuguese in 1503. The British garrisoned the island in 1815 to prevent a rescue of Napoleon from Saint Helena. It served as a provisioning station for the Royal Navy's West Africa Squadron on anti-slavery patrol. The island remained under Admiralty control until 1922, when it became a dependency of Saint Helena. During World War II, the UK permitted the US to construct an airfield on Ascension in support of transatlantic flights to Africa and anti-submarine operations in the South Atlantic. In the 1960s the island became an important space tracking station for the US. In 1982, Ascension was an essential staging area for British forces during the Falklands War. It remains a critical refueling point in the air-bridge from the UK to the South Atlantic. The island hosts one of four dedicated ground antennas (the others are on Diego Garcia (British Indian Ocean Territory), Kwajalein (Marshall Islands), and at Cape Canaveral, Florida (US)) that assist in the operation of the Global Positioning System (GPS) navigation system. NASA and the US Air Force also operate a Meter-Class Autonomous Telescope (MCAT) on Ascension as part of the deep space surveillance system for tracking orbital debris, which can be a hazard to spacecraft and astronauts.


Tristan da Cunha: The island group consists of Tristan da Cunha, Nightingale, Inaccessible, and Gough Islands. Tristan da Cunha is named after its Portuguese discoverer (1506); it was garrisoned by the British in 1816 to prevent any attempt to rescue Napoleon from Saint Helena. Gough and Inaccessible Islands have been designated World Heritage Sites. South Africa leases a site for a meteorological station on Gough Island.

Government of Samoa

New Zealand occupied the German protectorate of Western Samoa at the outbreak of World War I in 1914. It continued to administer the islands as a mandate and then as a trust territory until 1962, when the islands became the first Polynesian nation to reestablish independence in the 20th century. The country dropped the "Western" from its name in 1997.

Government of Senegal

The French colonies of Senegal and French Sudan were merged in 1959 and granted independence in 1960 as the Mali Federation. The union broke up after only a few months. Senegal joined with The Gambia to form the nominal confederation of Senegambia in 1982. The envisaged integration of the two countries was never implemented, and the union was dissolved in 1989. The Movement of Democratic Forces in the Casamance has led a low-level separatist insurgency in southern Senegal since the 1980s, and several peace deals have failed to resolve the conflict. Nevertheless, Senegal remains one of the most stable democracies in Africa and has a long history of participating in international peacekeeping and regional mediation. Senegal was ruled by a Socialist Party for 40 years until Abdoulaye WADE was elected president in 2000. He was reelected in 2007 and during his two terms amended Senegal's constitution over a dozen times to increase executive power and weaken the opposition. His decision to run for a third presidential term sparked a large public backlash that led to his defeat in a March 2012 runoff with Macky SALL, whose term runs until 2019. A 2016 constitutional referendum reduced the term to five years with a maximum of two consecutive terms for future presidents.

Government of Serbia

The Kingdom of Serbs, Croats, and Slovenes was formed in 1918; its name was changed to Yugoslavia in 1929. Communist Partisans resisted the Axis occupation and division of Yugoslavia from 1941 to 1945 and fought nationalist opponents and collaborators as well. The military and political movement headed by Josip Broz "TITO" (Partisans) took full control of Yugoslavia when their domestic rivals and the occupiers were defeated in 1945. Although communists, TITO and his successors (Tito died in 1980) managed to steer their own path between the Warsaw Pact nations and the West for the next four and a half decades. In 1989, Slobodan MILOSEVIC became president of the Republic of Serbia and his ultranationalist calls for Serbian domination led to the violent breakup of Yugoslavia along ethnic lines. In 1991, Croatia, Slovenia, and Macedonia declared independence, followed by Bosnia in 1992. The remaining republics of Serbia and Montenegro declared a new Federal Republic of Yugoslavia (FRY) in April 1992 and under MILOSEVIC's leadership, Serbia led various military campaigns to unite ethnic Serbs in neighboring republics into a "Greater Serbia." These actions ultimately failed and, after international intervention, led to the signing of the Dayton Peace Accords in 1995.

MILOSEVIC retained control over Serbia and eventually became president of the FRY in 1997. In 1998, an ethnic Albanian insurgency in the formerly autonomous Serbian province of Kosovo provoked a Serbian counterinsurgency campaign that resulted in massacres and massive expulsions of ethnic Albanians living in Kosovo. The MILOSEVIC government's rejection of a proposed international settlement led to NATO's bombing of Serbia in the spring of 1999. Serbian military and police forces withdrew from Kosovo in June 1999, and the UN Security Council authorized an interim UN administration and a NATO-led security force in Kosovo. FRY elections in late 2000 led to the ouster of MILOSEVIC and the installation of democratic government. In 2003, the FRY became the State Union of Serbia and Montenegro, a loose federation of the two republics. Widespread violence predominantly targeting ethnic Serbs in Kosovo in March 2004 led to more intense calls to address Kosovo's status, and the UN began facilitating status talks in 2006. In June 2006, Montenegro seceded from the federation and declared itself an independent nation. Serbia subsequently gave notice that it was the successor state to the union of Serbia and Montenegro.

In February 2008, after nearly two years of inconclusive negotiations, Kosovo declared itself independent of Serbia - an action Serbia refuses to recognize. At Serbia's request, the UN General Assembly (UNGA) in October 2008 sought an advisory opinion from the International Court of Justice (ICJ) on whether Kosovo's unilateral declaration of independence was in accordance with international law. In a ruling considered unfavorable to Serbia, the ICJ issued an advisory opinion in July 2010 stating that international law did not prohibit declarations of independence. In late 2010, Serbia agreed to an EU-drafted UNGA Resolution acknowledging the ICJ's decision and calling for a new round of talks between Serbia and Kosovo, this time on practical issues rather than Kosovo's status. Serbia and Kosovo signed the first agreement of principles governing the normalization of relations between the two countries in April 2013 and are in the process of implementing its provisions. Prime Minister Aleksandar VUCIC, has promoted an ambitious goal of Serbia joining the EU by 2020. Under his leadership, in January 2014 Serbia opened formal negotiations for accession.

Government of Sierra Leone

The British set up a trading post near present-day Freetown in the 17th century. Originally the trade involved timber and ivory, but later it expanded into slaves. Following the American Revolution, a colony was established in 1787 and Sierra Leone became a destination for resettling black loyalists who had originally been resettled in Nova Scotia. After the abolition of the slave trade in 1807, British crews delivered thousands of Africans liberated from illegal slave ships to Sierra Leone, particularly Freetown. The colony gradually expanded inland during the course of the 19th century; independence was attained in 1961. Democracy is slowly being reestablished after the civil war (1991-2002) that resulted in tens of thousands of deaths and the displacement of more than 2 million people (about one third of the population). The military, which took over full responsibility for security following the departure of UN peacekeepers at the end of 2005, has developed as a guarantor of the country's stability; the armed forces remained on the sideline during the 2007 and 2012 national elections. In March 2014, the closure of the UN Integrated Peacebuilding Office in Sierra Leone marked the end of more than 15 years of peacekeeping and political operations in Sierra Leone. The government's stated priorities include furthering development - including recovering from the Ebola epidemic - creating jobs, and stamping out endemic corruption.

Government of Singapore

Singapore was founded as a British trading colony in 1819. It joined the Malaysian Federation in 1963 but was ousted two years later and became independent. Singapore subsequently became one of the world's most prosperous countries with strong international trading links (its port is one of the world's busiest in terms of tonnage handled) and with per capita GDP equal to that of the leading nations of Western Europe.

Government of Sint Maarten

Although sighted by Christopher COLUMBUS in 1493 and claimed for Spain, it was the Dutch who occupied the island in 1631 and began exploiting its salt deposits. The Spanish retook the island in 1633, but continued to be harassed by the Dutch. The Spanish finally relinquished the island of Saint Martin to the French and Dutch, who divided it amongst themselves in 1648. The establishment of cotton, tobacco, and sugar plantations dramatically expanded African slavery on the island in the 18th and 19th centuries; the practice was not abolished in the Dutch half until 1863. The island's economy declined until 1939 when it became a free port; the tourism industry was dramatically expanded beginning in the 1950s. In 1954, Sint Maarten and several other Dutch Caribbean possessions became part of the Kingdom of the Netherlands as the Netherlands Antilles. In a 2000 referendum, the citizens of Sint Maarten voted to become a self-governing country within the Kingdom of the Netherlands. The change in status became effective in October of 2010 with the dissolution of the Netherlands Antilles.

Sint Maarten is a constituent country within the Kingdom of the Netherlands. It has full autonomy in internal affairs since October 2010. The Dutch Government remains responsible for defense and foreign affairs.
