Lee Kuan Yew was born in 1923 in Singapore to a middle-class family. He helped found the People's Action Party in 1954 and led them to victory in 1959, becoming Singapore's first prime minister. As prime minister, Lee transformed Singapore's economy and established it as a modern, wealthy nation. However, tensions caused Singapore to leave Malaysia in 1965. Lee remained an influential figure, resigning as prime minister in 1990 but continuing to offer advice. He worked tirelessly to build Singapore until his death in 2015.
