In 1937, Japan invaded China and in September 1939, Germany invaded Poland. In October 1940, the 295th and 296th Infantry Regiments of the Puerto Rican National Guard, founded by Major General Luis R. Esteves, were called into Federal Active Service and assigned to the Puerto Rican Department in accordance with the existing War Plan Orange. During that period of time, Puerto Rico's economy was suffering from the consequences of the Great Depression, and unemployment was widespread. Unemployment was one of the reasons that some Puerto Ricans chose to join the Armed Forces.
