Why is totalitarianism a twentieth centry phenomenon?

Totalitarianism emerged as a distinct political phenomenon in the twentieth century primarily due to the socio-political upheavals following World War I, the rise of industrialization, and the influence of mass media. The destruction of traditional power structures and the desire for stability allowed authoritarian leaders to exploit economic and social discontent, leading to regimes that sought total control over public and private life. Additionally, ideologies like fascism and communism gained traction, promoting centralized power and the suppression of dissent. These conditions, unique to the twentieth century, facilitated the establishment of totalitarian states.
