Why 1.5 Million People Live on a Desert Island With No Rivers

Bahrain is a low, sun-baked archipelago in the Persian Gulf with no permanent rivers, no lakes and barely any rain, yet around 1.5 million people live there. Ancient poets called it a paradise of sweet water, its land keeps growing every decade, and today almost every glass of drinking water is made by machines. So how did a desert island with no rivers become one of the most crowded countries on Earth? In this video we explore the geography behind Bahrain: land reclaimed from the sea, the fossil groundwater that once rose through springs on land and on the seabed, the Dilmun civilisation, the pearl divers who drank from submarine springs, the pearl crash of the 1930s, the first oil strike on the Arab side of the Gulf in 1932, banks, the King Fahd Causeway and a huge migrant workforce, the springs falling silent, the desalination plants that now supply most of its water, the US Navy's Fifth Fleet, and how the 2026 Iran war turned water into a target.
