Because of its Pacific preeminence and connections, California's role in World War II was largely unmatched by any other state. The 40-year clash between the state and its Japanese population, beginning in 1900, set the stage for the Pearl Harbor attack of December 7, 1941, that thrust America into the war. That attack led to the mass removal of California's residents of Japanese ancestry to barbed wire encampments. Meanwhile, the state's military installations, shipyards, and airplane factories were instrumental in waging war in the Pacific, while UC Berkeley's leadership in the atomic bomb project ensured a decisive and controversial end to the global conflict.
In the war's aftermath, California emerged as more thoroughly industrialized, more heavily populated, and an even more dominant force in Pacific commerce and security affairs as well as aerospace enterprises than in the depression era. While the Pacific Coast states of Oregon and Washington likewise experienced wartime growth, in most regards they were greatly eclipsed by California. The Golden State's phenomenal military infrastructure, necessitated by war, gave rise to a long-lasting, economic boom beginning in the late 1940s and undergirded by agriculture. During the war years and afterward, Greater California's influence in the Far West, the nation, the Pacific Basin, and globally became greater still.
