Immanuel Wallerstein

Immanuel Wallerstein was an American sociologist and economic historian. He is perhaps best known for his development of the general approach in sociology which led to the emergence of his world-systems approach. He was the author of "The Decline of American Power: The US in a Chaotic World" (2003, New Press) and "Historical Capitalism with Capitalist Civilization" (2011). Wallerstein died in 2019 at age 88.
