Why did European and Russian civilizations die during World War 1?

European and Russian civilizations faced severe destabilization during World War I due to the immense human and economic toll of the conflict. The war led to unprecedented loss of life, social upheaval, and political turmoil, resulting in the collapse of empires such as the Austro-Hungarian, Ottoman, and Russian Empires. In Russia, the war exacerbated existing social tensions and economic hardships, ultimately leading to the Bolshevik Revolution in 1917. These factors collectively contributed to the decline of traditional European and Russian power structures.
