The Blue Shirts during the 1930s became one of the most influential and feared political movements in China. To both contemporaries and historians, however, the Blue Shirt movement has been a shadowy force, known mostly through hearsay, with little solid information regarding its doctrine or its activities. Now, on the basis of memoirs, interviews, and especially Japanese intelligence reports of the 1930s, a rough picture of this secret organization can be pieced together. And the image that emerges is not simply a terrorist organization, but a political faction that reflected the concerns and ideals of many Chinese during the troubled Nanking decade. This study will, it is hoped, not only provide an insight into the nature of Kuomintang rule, but will shed light on a previously unexamined species of the political genus, fascism.
