Dubai has experienced rapid economic development over the past 50 years, transitioning from a pearl diving and fishing economy to an international hub of trade, tourism, and real estate development. It has grown from a small trading port to a city of over 2 million people through strategic investments in infrastructure like the Burj Khalifa (the world's tallest building), Palm Islands, Dubai Mall (the world's largest shopping mall), and tourism attractions such as Ski Dubai. This transformation was enabled by the discovery of oil in 1966 and a strategic plan to diversify Dubai's economy beyond oil through mega-developments that have made it a global destination.
