Founded in 963, Luxembourg became a grand duchy in 1815 and an independent state under the Netherlands. It lost more than half of its territory to Belgium in 1839 but gained a larger measure of autonomy. Full independence was attained in 1867. Overrun by Germany in both world wars, it ended its neutrality in 1948 when it entered into the Benelux Customs Union and when it joined NATO the following year. In 1957, Luxembourg became one of the six founding countries of the EEC (later the EU), and in 1999 it joined the euro currency area.

Luxembourg is constitutional monarchy.

In 788, about a century after the Arab conquest of North Africa, a series of Moroccan Muslim dynasties began to rule in Morocco. In the 16th century, the Sa'adi monarchy, particularly under Ahmad al-MANSUR (1578-1603), repelled foreign invaders and inaugurated a golden age. The Alaouite Dynasty, to which the current Moroccan royal family belongs, dates from the 17th century. In 1860, Spain occupied northern Morocco and ushered in a half century of trade rivalry among European powers that saw Morocco's sovereignty steadily erode; in 1912, the French imposed a protectorate over the country.

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.

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.

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.

El Salvador achieved independence from Spain in 1821 and from the Central American Federation in 1839. A 12-year civil war, which cost about 75,000 lives, was brought to a close in 1992 when the government and leftist rebels signed a treaty that provided for military and political reforms.

El Salvador is a presidential republic.

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.

Slovakia's roots can be traced to the 9th century state of Great Moravia. Subsequently, the Slovaks became part of the Hungarian Kingdom, where they remained for the next 1,000 years. Following the formation of the dual Austro-Hungarian monarchy in 1867, language and education policies favoring the use of Hungarian (Magyarization) resulted in a strengthening of Slovak nationalism and a cultivation of cultural ties with the closely related Czechs, who were under Austrian rule.

The Slovene lands were part of the Austro-Hungarian Empire until the latter's dissolution at the end of World War I. In 1918, the Slovenes joined the Serbs and Croats in forming a new multinational state, which was named Yugoslavia in 1929. After World War II, Slovenia became a republic of the renewed Yugoslavia, which though communist, distanced itself from Moscow's rule. Dissatisfied with the exercise of power by the majority Serbs, the Slovenes succeeded in establishing their independence in 1991 after a short 10-day war.

Chad, part of France's African holdings until 1960, endured three decades of civil warfare, as well as invasions by Libya, before peace was restored in 1990. The government eventually drafted a democratic constitution and held flawed presidential elections in 1996 and 2001. In 1998, a rebellion broke out in northern Chad, which has sporadically flared up despite several peace agreements between the government and insurgents. In June 2005, President Idriss DEBY held a referendum successfully removing constitutional term limits and won another controversial election in 2006.

French Togoland became Togo in 1960. Gen. Gnassingbe EYADEMA, installed as military ruler in 1967, ruled Togo with a heavy hand for almost four decades. Despite the facade of multi-party elections instituted in the early 1990s, the government was largely dominated by President EYADEMA, whose Rally of the Togolese People (RPT) party has been in power almost continually since 1967 and its successor, the Union for the Republic, maintains a majority of seats in today's legislature.

Present-day Turkmenistan covers territory that has been at the crossroads of civilizations for centuries. The area was ruled in antiquity by various Persian empires, and was conquered by Alexander the Great, Muslim armies, the Mongols, Turkic warriors, and eventually the Russians. In medieval times, Merv (located in present-day Mary province) was one of the great cities of the Islamic world and an important stop on the Silk Road. Annexed by Russia in the late 1800s, Turkmenistan later figured prominently in the anti-Bolshevik movement in Central Asia.
