How did Kuwait develop?

Kuwait started developing about 50 years back, after the discovery of petroleum. They started exporting petroleum in huge amounts, and consequently became rich. They used this money to develop their country. In 1990, Saddam Hussein of Iraq, a neighbouring country, invaded Kuwait and devastated the country. With help from US and around the world, Kuwait was liberated in 1991 after 7 months of the invasion. Since then they had to repeat the same process of exporting petroleum and subsequently became wealthy again.
