Causes

Prior to World War I, under the Anglo-Ottoman Convention of 1913, Kuwait was considered to be an autonomous caza within Ottoman Iraq. Following the war, Kuwait fell under British rule and later became an independent emirate. However, Iraqi officials did not accept the legitimacy of Kuwaiti independence or the authority of the Kuwaiti Emir. Iraq never recognized Kuwait's sovereignty and in the 1960s, the United Kingdom deployed troops to Kuwait to deter an Iraqi annexation.

During the Iran-Iraq War of the 1980s, Kuwait was allied with Iraq, largely due to desiring Iraqi protection from Shi'ite Iran. After the war, Iraq was heavily indebted to several Arab countries, including a $14 billion debt to Kuwait. Iraq hoped to repay its debts by raising the price of oilthrough OPEC oil production cuts, but instead, Kuwait increased production, lowering prices, in an attempt to leverage a better resolution of their border dispute. In addition, Iraq began to accuse Kuwait of slant drilling into neighboring Iraqi oil fields, and furthermore charged that it had performed a collective service for all Arabs by acting as a buffer against Iran and that therefore Kuwait and Saudi Arabia should negotiate or cancel Iraq's war debts. Iraqi President Saddam Husseins primary two-fold justification for the war was a blend of the assertion of Kuwaiti territory being an Iraqi province arbitrarily cut off by imperialism, with the use of annexation as retaliation for the "economic warfare" Kuwait had waged through slant drilling into Iraq's oil supplies while it had been under Iraqi protection.

The war with Iran had also seen the destruction of almost all of Iraq's port facilities on the Persian Gulf, cutting off Iraq's main trade outlet. Many in Iraq, expecting a resumption of war with Iran in the future, felt that Iraq's security could only be guaranteed by controlling more of the Gulf Coast, including more secure ports. Kuwait thus made a tempting target.

Ideologically, the invasion of Kuwait was justified through calls to Arab nationalism. Kuwait was described as a natural part of Iraq carved off by British imperialism. The annexation of Kuwait was described as a step on the way to greater Arab union. Other reasons were given as well. Hussein presented it as a way to restore the empire of Babylon in addition to the Arab nationalist rhetoric. The invasion was also closely tied to other events in the Middle East. The First Intifada by the Palestinians was raging, and most Arab states, including Kuwait, Saudi Arabia and Egypt, were dependent on western alliances. Saddam thus presented himself as the one Arab statesman willing to stand up to Israel and the U.S.
