On March 1, 1919, Korean activist leaders read aloud their Declaration of Independence, which quickly encouraged more demonstrations around the peninsula. Colonial Japanese forces swiftly suppressed these protests and demands for independence went unheeded, but the movement did ultimately help shape modern Korean nationhood.
The attached excerpts are from a March 2019 Carnegie Council podcast entitled "The Crack-Up: 1919 & the Birth of Modern Korea, with Kyung Moon Hwang." The podcast is based off The New York Times opinion piece "The Birth of Korean Nationhood" written by historian Kyung Moon Hwang.
