Dankwart Alexander Rustow (December 21, 1924 – August 3, 1996) was a professor of political science and sociology.
He is prominent for his research on democratization.
In his seminal 1970 article 'Transitions to Democracy: Toward a Dynamic Model,' Rustow broke from the prevailing schools of thought on how countries became democratic.
Disagreeing with the heavy focus on necessary social and economic pre-conditions for democracy, he argued that national unity was the necessary precondition for democracy.
