Charles King Armstrong is an American historian and the Korea Foundation Professor of Korean Studies at Columbia University.
His works deal with revolutions, cultures of socialism, architectural history, and diplomatic history in the contexts of East Asia and modern Korea, with a focus on North Korea.
His 2013 book, Tyranny of the Weak, won the John K.
Fairbank Prize, but he returned the prize in 2017 after issues with the citations, including plagiarism and source fabrication, were raised.
A Columbia University investigation later determined that he had committed plagiarism.
