Archaeological finds on Failaka, the largest of Kuwait’s nine islands, suggests it was a trading post at the time of the ancient Sumerians. Failaka appears to have continued to serve as a market for approximately 2,000 years, and was known to the ancient Greeks. Despite its long history as a market and sanctuary for traders, Failaka appears to have been abandoned as a permanent settlement in the 1st century A.D. Kuwait's modern history began in the 18th century with the founding of the city of Kuwait by the Uteiba, a subsection of the Anaiza tribe, who are believed to have traveled north from Qatar.
Threatened in the 19th century by the Ottoman Turks and various powerful Arabian Peninsula groups, Kuwait sought the same treaty relationship Britain had already signed with the Trucial States (UAE) and Bahrain. In January 1899, the ruler Sheikh Mubarak Al Sabah --"the Great"-- signed an agreement with the British Government that pledged himself and his successors neither to cede any territory, nor to receive agents or representatives of any foreign power without the British Government's consent, in exchange for protection and an annual subsidy. When Mubarak died in 1915, the population of Kuwait of about 35,000 was heavily dependent on shipbuilding (using wood imported from India) and pearl diving.
Mubarak was succeeded as ruler by his sons Jabir (1915-17) and Salim (1917-21). Kuwait’s subsequent rulers have descended from these two brothers. Sheikh Ahmed al-Jabir Al Sabah ruled Kuwait from 1921 until his death in 1950, a period in which oil was discovered and in which the government attempted to establish the first internationally recognized boundaries; the 1922 Treaty of Uqair set Kuwait’s border with Saudi Arabia and also established the Kuwait-Saudi Arabia Neutral Zone, an area of about 5,180 sq. km. (2,000 sq. mi.) adjoining Kuwait's southern border.
Kuwait achieved independence from the British under Sheikh Ahmed’s successor, Sheikh Abdullah al-Salim Al Sabah. By early 1961, the British had already withdrawn their special court system, which handled the cases of foreigners resident in Kuwait, and the Kuwaiti Government began to exercise legal jurisdiction under new laws drawn up by an Egyptian jurist. On June 19, 1961, Kuwait became fully independent following an exchange of notes with the United Kingdom.
Kuwait enjoyed an unprecedented period of prosperity under Amir Sabah al-Salim Al Sabah, who died in 1977 after ruling for 12 years. Under his rule, Kuwait and Saudi Arabia signed an agreement dividing the Neutral Zone (now called the Divided Zone) and demarcating a new international boundary. Both countries share equally the Divided Zone's petroleum, onshore and offshore. The country was transformed into a highly developed welfare state with a free market economy.
In August 1990, Iraq attacked and invaded Kuwait. Kuwait's northern border with Iraq dates from an agreement reached with Turkey in 1913. Iraq accepted this claim in 1932 upon its independence from Turkey. However, following Kuwait's independence in 1961, Iraq claimed Kuwait, arguing that Kuwait had been part of the Ottoman Empire subject to Iraqi suzerainty. In 1963, Iraq reaffirmed its acceptance of Kuwaiti sovereignty and the boundary it agreed to in 1913 and 1932, in the "Agreed Minutes between the State of Kuwait and the Republic of Iraq Regarding the Restoration of Friendly Relations, Recognition, and Related Matters."
Following several weeks of aerial bombardment, a UN-mandated coalition led by the United States began a ground assault in February 1991 that liberated Kuwait. During the 7-month occupation by Iraq, the Amir, the Government of Kuwait, and many Kuwaitis took refuge in Saudi Arabia and other nations. The Amir and the government successfully managed Kuwaiti affairs from Saudi Arabia, London, and elsewhere during the period, relying on substantial Kuwaiti investments available outside Kuwait for funding and war-related expenses.
Following liberation, the UN, under Security Council Resolution 687, demarcated the Iraq-Kuwait boundary on the basis of the 1932 and the 1963 agreements between the two states. In November 1994, Iraq formally accepted the UN-demarcated border with Kuwait, which had been further spelled out in UN Security Council Resolutions 773 and 883.
