World Wars and Ideologies: Nationalism and Marxism

The nineteenth century stands as one of the most transformative epochs in human history, characterized by the gradual dissolution of traditional multi-ethnic empires and the violent birth of modern nation-states. In this comprehensive lecture from Yeshivat Har Bracha, Rabbi Ze'ev Sultanovitch analyzes the deep ideological currents that set the stage for the global catastrophes of the twentieth century. By examining the interplay between nationalism and socialism, the lesson illuminates how philosophical concepts translated into massive socio-political movements that reshaped the globe.

At the outset of the era, Europe was dominated by sprawling empires such as Britain, Austria-Hungary, and Russia, where loyalty was owed to a crown or dynasty rather than a shared linguistic or cultural identity. However, the shockwaves of the French Revolution and the subsequent conquests of Napoleon Bonaparte fundamentally altered this landscape. Napoleon's armies inadvertently spread the seeds of national consciousness across the continent. While French rule aimed at imperial expansion, it provoked a strong counter-reaction, vividly illustrated in Johann Gottlieb Fichte's addresses to the German nation, which sparked a romantic, culture-based nationalism symbolized by the folklore studies of the Brothers Grimm.

The nineteenth century also witnessed the tension between civic and ethnic nationalism. The definition of a nation shifted from a political community bound by laws and citizenship—the demos—to an organic collective bound by blood, shared heritage, and culture—the ethnos. This duality later carried profound historical consequences, feeding into movements ranging from the unification of Italy and Germany to darker perversions like fascism and Nazi ideology. Concurrently, Jewish thinkers like Moses Hess began grappling with the implications of nationalism for their own people, bridging ancient identity with modern political aspirations.

Parallel to the rise of nationalism, the economic and philosophical framework of socialism emerged as an equally potent revolutionary force. Karl Marx, supported intellectually and financially by Friedrich Engels, formulated a deterministic view of human history driven by economic conflicts. According to Marx, history progresses through distinct stages: from primitive communism, through slave-holding societies and feudalism, to industrial capitalism. Each stage is characterized by an inherent struggle between oppressors and oppressed classes.

The Industrial Revolution served as the great accelerator for this theoretical framework. The invention of the steam engine and the rise of mechanized factories birthed a massive urban proletariat—the modern working class. This socio-economic upheaval created stark disparities of wealth, setting the stage for the 'Communist Manifesto' and calls for global revolution. Meanwhile, events outside Europe, such as the American Civil War, reflected a complex interplay between moral imperatives and underlying economic interests.

Ultimately, Rabbi Sultanovitch's lecture demonstrates that the First and Second World Wars were not merely accidental military conflicts, but the explosive culmination of unresolved ideological tensions. The competing claims of national self-determination and international class solidarity pulled societies in opposite directions, creating an unstable global order. Understanding these nineteenth-century foundations remains essential for comprehending the modern political landscape and the enduring power of ideological movements.
