Japan's militarism and ultranationalism surged in the early 20th century, fueled by economic hardship, political instability, and cultural factors. The Great Depression , weak civilian governments, and state-promoted ideologies of national superiority set the stage for radical change.
The military's growing influence in politics, coupled with ultranationalist ideologies, eroded Japan's democracy. Expansionist policies, emperor worship, and the suppression of dissent transformed the nation, leading to aggressive territorial expansion and eventual war.
