ym´n, officially Republic of Yemen, republic (2005 est. pop. 20,727,000), 207,300 sq mi (535,800 sq km), SW Asia, at the southern edge of the Arabian peninsula. The present nation of Yemen was formed in 1990, when the Yemen Arab Republic (the former Yemen or Northern Yemen) and the People's Democratic Republic of Yemen (the former Southern Yemen) were unified. Yemen is bordered on the north by Saudi Arabia, on the east by Oman, on the south by the Gulf of Aden, and on the west by the Red Sea. The islands of Kamaran, in the Red Sea, Perim, in the Bab al-Mandeb, and Socotra, in the Arabian Sea, are part of Yemen. Sana is the capital; the port of Aden is the country's commercial capital.
Yemen has a narrow, coastal plain, stretching more than 700 mi (1,130 km), along the southern edge of the Arabian peninsula. It also has interior highlands and an eastern desert. The highlands, which are actually a section of the upturned Arabian plateau, are the highest part (rising to more than 12,000 ft/3,660 m) of the Arabian peninsula. They receive an annual average rainfall of c.20 in. (50 cm), making them also the wettest part of the peninsula; most of the precipitation occurs during the summer rainy season. The remainder of Yemen is hot and virtually rainless in the coastal regions. Numerous wadis radiate from the highlands, but Yemen has no permanent streams; oases and springs provide local water needs.
Yemen is the most populous country on the Arabian Peninsula. The great majority of the population is Arab (90%); some are Afro-Arab. Minorities include Indians, Somalis, and Europeans. Islam is the main religion. The north of Yemen is nearly 100% Muslim, both Sunni and Shiite; the south is predominantly Muslim, but also has Christians and Hindus. Between 1948 and 1950 about 50,000 Yemeni Jews emigrated to Israel. Arabic is the nation's principal language. The tribal social structure is still prevalent in the country, although its importance diminishes along the coast, due to more foreign contact. In addition to Sana and Aden, other important cities are Hodeida, Mukalla, Taiz, Ibb, and Abyan. Administratively, the country is divided into 17 governates.
N Yemen produces grain, fruits, vegetables, khat (a stimulant-containing shrub), cotton, coffee, and livestock but is dependent on imports for most of its essential needs. Terraced agriculture, dating from ancient times, is still practiced. S Yemen is one of the poorest areas of the Arabian peninsula. The climate is arid, and only a fraction of the land is arable. Pastoralism is prevalent in the south, and the greatest amount of industry is located in Aden. Manufacturing, including food processing and the production of cotton textiles, leather goods, cement, and aluminum products, has increased but provides little real revenue. The country produces and refines petroleum, and oil export revenues have boosted the economy since the late 1980s. Yemen's GDP is also supplemented by remittances from Yemenis working abroad and by large amounts of foreign aid. One of the principal reasons for Southern Yemen's merger with (Northern) Yemen in 1990 was the steady decline of its economy and the loss of Soviet political and economic support. Pervasive corruption, however, has hindered new economic development in unified Yemen.
Yemen is governed under the constitution of 1991, as amended in 1994 and 2001. The president is the head of state and is elected by popular vote for a seven-year term. The bicameral national legislature consists of the House of Representatives, with 301 members who are popularly elected to six-year terms, and the Shura Council, with 111 members who are appointed by the president. The main political parties are the General People's Congress and the Islamic Reform Grouping or Isiah party.
The earliest recorded civilizations of S Arabia were the Minaean and Sabaean. The Sabaean kingdom (see Sheba) flourished from c.750 BC to c.115 BC, with Marib (located east of Sana) the capital after c.600 BC Sabaean society was highly developed technically, as witnessed by the remains of a great dam at Marib that was the center of a large irrigation system. The Himyarites, who followed the Sabaeans, were invaded by the Romans (1st cent. BC) and were occupied by the Ethiopians (c.AD 340–AD 378). During the second Himyarite kingdom Christianity and Judaism took root in Yemen. Ethiopia again conquered the country in 525. After a Persian period (575–628), Islam came to Yemen, which was soon reduced to a province of the Muslim caliphate.
After the breakup of the caliphate, Yemen came under the control of the rising Rassite dynasty, imams of the Zaidi sect who built the theocratic political structure of Yemen that lasted until 1962. The Fatamid caliphs of Egypt occupied most of Yemen from c.1000 until c.1175, when it fell to the Ayyubids, who ruled until c.1250. By 1520, Yemen formed part of the Ottoman Empire, which exercised at least nominal sovereignty until the end of World War I. A turbulent wave of Wahhabism, a puritanical sect of Islam, swept across the Arabian peninsula at the opening of the 19th cent. and drove out the Zaidi imams. Ibrahim Pasha of Egypt, acting in the name of the Ottoman sultan, drove out the Wahhabis in 1818, and the Egyptians remained until 1840. The Ottoman Turks then replaced the Egyptians, giving the imam full autonomy in the interior.
After the Ottoman evacuation (1918), Imam Yahya moved to expand Yemen's territory, but his only gain was the port and surrounding area of Hodeida. In 1934, after a brief Saudi Arabian invasion and skirmishes with Great Britain (which had the protectorate of Aden), Yemen's boundaries were fixed by treaty with Saudi Arabia and Great Britain. However, clashes on the Aden border continued sporadically. Modifying its traditional policy of isolation, Yemen became more active in foreign affairs after World War II; it joined the Arab League in 1945 and the United Nations in 1947 and established diplomatic relations with other nations. However, the imam, as both king and spiritual leader, continued to rule along theocratic lines.
Dissatisfaction, hitherto rapidly suppressed, grew, and in 1948 a palace revolt broke out, and the old Imam Yahya was assassinated. Crown Prince Ahmad drove out the insurgents and succeeded as imam. The new ruler accepted technical and economic assistance from both the West and the Communist bloc. From 1958 to 1961, Yemen joined with the United Arab Republic (Egypt and Syria) to form the United Arab States, which in reality was a paper alliance. Disorders broke out in 1959, and Imam Ahmad survived an assassination attempt in 1961. After his death in 1962, Imam Ahmad was succeeded by Crown Prince Muhammad al-Badr (later Imam Mansur Billah Muhammad), who favored a neutralist foreign policy. Soon afterward a revolt headed by pro-Egyptian army officers deposed the imam, but he escaped and led royalist tribes against the new government.
The ruling junta, commanded by Col. Adallah al-Salal, proclaimed a republic, and the army contained the imam's forces. Yemen then became an international battleground, with Egypt supporting the republicans and Saudi Arabia and Jordan the royalists. The Yemeni republicans split into opposing factions on the issue of Egyptian support. In an administrative reorganization in 1966, the independent government of Premier Hassan al-Amri was ousted by a strongly pro-Egyptian regime, with al-Salal assuming the office of premier. Many of al-Amri's supporters were arrested or removed from office. In 1967, by mutual agreement, Egyptian troops were withdrawn from Yemen, and Saudi Arabian aid to the royalists was halted. In Nov., 1967, al-Salal's government was overthrown while he was abroad, and a three-man republican council was formed with Qadi Abd al-Rahman al-Iryani (one of the anti-Egyptian leaders) as chairman; al-Amri resumed the premiership.
Fighting between the republicans and the royalists continued until 1970, when Saudi Arabia formally recognized the republican regime and stopped aid to the royalists. Between 1967 and 1972 frequent border clashes occurred between Yemen and Southern Yemen, until an accord was signed (1972) to merge the two countries. However, by 1974 the agreement had not been implemented, and fighting continued between the two states. On June 12, 1974, Chairman al-Iryani resigned after a period of internal political tension, and the next day a group of army officers led by Col. Ibrahim al-Hamidi staged a nonviolent coup. The officers established a command council to govern the country, suspended the constitution, and reestablished civilian rule. Al-Hamidi was assassinated in Oct., 1977, and was succeeded by Lt.-Col. Ahmad al-Ghashmi, who continued civilian administration until his assassination in June, 1978.
The next president, Lt.-Col. Ali Abdullah Saleh, strengthened various democratic procedures. In early 1979 border fighting with neighboring Southern Yemen erupted into full-scale war. Peace was soon established, however, and another unification agreement was devised. Saleh was elected for his third term in 1988.
A number of ancient empires, including the Minaean, Sabaean, and Himyarite, flourished in southern Yemen. The region came under Muslim influence in the 7th cent. In the 16th cent. it became part of the Ottoman Empire and came under the suzerainty of the imams of Yemen. (For a more detailed history, see above history of Northern Yemen or see Arabia.)
The British presence in Southern Yemen began in 1839, when forces of the British East India Co. occupied Aden. In 1854 and 1857 the Kuria Muria and Perim islands were ceded to the British, and other mainland areas were purchased by them. Between 1886 and 1914, Britain signed a number of protectorate treaties with local rulers. In 1937 the area, which by then consisted of 24 sultanates, emirates, and sheikhdoms, was designated the Aden Protectorate and was divided for administrative purposes into the East Aden protectorate and the West Aden protectorate. In 1959 six small states of the West Aden protectorate formed the Federation of the Emirates of the South; it was later enlarged to 10 members. Despite considerable opposition from its population, the Aden colony proper was made part of the federation (1963), which was then renamed the Federation of South Arabia (see South Arabia, Federation of).
By 1965, 16 tribal states had joined the federation. However, nationalist groups in Aden remained adamantly opposed to the federation and began a terrorist campaign against the British. Two rival nationalist groups emerged: the National Liberation Front (NLF) and the Front for the Liberation of Occupied South Yemen (FLOSY). Although Britain had promised to withdraw from the region by 1968, the NLF, which had emerged as the dominant group by 1967, forced the collapse of the federation after taking control of the governments of all the component states. Britain accelerated its withdrawal, and Southern Yemen became independent in Nov., 1967, with Qahtan al-Shaabi of the NLF the first president. In June, 1969, he resigned, and was succeeded by Rubayi Ali. In 1970 the country received a new constitution and was renamed the People's Democratic Republic of Yemen.
Following independence border disputes arose with Oman and the Yemen Arab Republic, some of which led to armed clashes. An accord was signed with the Yemen Arab Republic in 1972 calling for the end of fighting and the merger of the two countries. However, the agreement was not to be implemented for several years. In Apr., 1972, the government of Southern Yemen suffered a severe blow when 25 of its top officials were killed in an airplane crash. Rubayi Ali was ousted in June, 1978, by Abdalfattah Ismail, a radical rival who in 1979 signed a 20-year relation treaty with the Soviet Union. Soviet influence, including the presence of naval bases, became predominant in Southern Yemen, which was the Arab world's only Marxist state. Fighting with Northern Yemen again broke out in Feb., 1979, but was resolved one month later by a peace treaty.
In 1983, Ali Nasser Muhammad, Ismail's successor as president, restored relations with Saudi Arabia and Oman. In Jan., 1986, Muhammad tried to eliminate internal party opposition by killing party leaders and former president Ismail, but rival political fighting erupted for two weeks, after which Muhammad fled to Ethiopia. His supporters were mostly eliminated by the administration of Haider Abu Bakr al-Attas, Muhammad's successor. In Oct., 1988, Attas visited Oman, the first Southern Yemen leader to do so.
The leaders of the two Yemens met in Dec., 1989, when final unification agreements were made, and the borders were opened in Feb., 1990. On May 22 of that year, the two Yemens were officially united. North Yemen president Saleh became the leader of a unified Yemen, and Sana became the nation's capital. By 1993, however, relations between north and south had again grown tense. Fighting between northern and southern army units in 1994 erupted into a civil war between southern secessionists and Yemen's northern-based government. The war lasted for nine weeks and was decisively won by northern forces. Subsequently, Saleh was officially elected by parliament as president of the country, and a coalition government that excluded the leading southern party was established. The new government imposed unpopular economic austerity measures. Muslim extremists committed sporadic acts of violence in the south, and armed tribespeople from remote areas staged kidnappings of foreign tourists.
Yemen's armed forces clashed with Eritrea over control of the Hanish Islands in the Red Sea in the early 1990s; the Hague Tribunal awarded the islands to Yemen in 1998. The president's party won nearly two thirds of the seats in the 1997 legislative elections. In Sept., 1999, in Yemen's first direct presidential election, Saleh was returned to office; candidates from opposition parties were not approved to run, and the government was charged with fraudulently inflating the vote count. In Oct., 2000, the U.S.S. Cole was damaged by a suicide bombing while anchored at Aden and the British embassy was bombed. Also in 2000, a border treaty ending disputes with Saudi Arabia that dated to the 1930s was signed.
President Saleh announced support for the U.S. war on terror in 2001 and subsequently received American aid and made some moves against Muslim extremists, but the terror attacks also continued. Saleh's General People's Congress won more than two thirds of the seats in the 2003 legislative elections. In June, 2004, government forces began raids against supporters of Shiite cleric Hussein al-Hawthi, who was accused of sedition and extremism. The cleric had denounced the government's pro-American policies and government corruption. Several months of fighting in N Yemen, in which hundreds died, followed, and in September Sheikh Hawthi was killed and a cease-fire mediated. Fighting erupted again in Apr., 2005, when the government attacked Hawthi's followers after unsuccessful negotiations. Almost a year later some 600 rebels were released in an amnesty, but attacks continued spordically until June, 2007, when a cease-fire was agreed to.
Meanwhile, in July, 2005, fuel price increases sparked protests and riots across Yemen, leading the government to roll the increases back somewhat. That same month the president said he would not seek a new term in Sept., 2006, a position he reversed a year later. In the 2006 presidential Saleh was reelected with more than three-fourths of the vote, but the opposition rejected the results. Despite irregularities, the election was generally regarded as an improvement over the previous presidential poll.
