Introduction Nationalism is one of the most defining, transformative, and at the same time, one of the most contradictory ideologies of modern history. In its simplest definition, it is a system of thought that argues that people around the world are divided into political communities called "nations," each possessing its own right to sovereignty, united around a common identity, and that an individual's highest loyalty should belong to this nation. This idea has shattered the understandings of legitimacy that have dominated a large part of human history (dynastic loyalty, religious affiliation, imperial subjects), bringing the source of political authority from the heavens down to the earth, from God to the "nation." However, nationalism is not a uniform and fixed ideology. It is an extremely fluid phenomenon that is constantly reinterpreted according to historical and social contexts, capable of taking on contradictory forms. On one hand, it has become the banner of the liberation and self-determination struggles of oppressed peoples; on the other hand, it has been used as a legitimizing ideology for the most ruthless colonialism, ethnic cleansing, and wars. It has inspired the ideals of "liberty, equality, fraternity" of the French Revolution, while also providing a theoretical foundation for the racist imperialism of Nazi Germany. This contradictory nature makes understanding nationalism both necessary and extremely complex. This narrative will address the great and contradictory journey of nationalism in three main sections, delving into the finest details. The first section will start from the pre-modern world, examining how Enlightenment thought and the French Revolution gave birth to the idea of nationalism; the second section will explore how this idea became popular and transformed into a mass movement through various social, economic, and cultural dynamics throughout the 19th century; the third section will investigate how this global movement took root among the Turkish elements in the Ottoman Empire and how a unique example of Turkish nationalism emerged. 1. Chapter: The Birth of the Idea of Nationalism: The Collapse of the Old World and the Search for a New Legitimacy (18th Century - 1815) Nationalism is a completely new phenomenon that did not exist in the pre-modern world. This does not mean that before it, people did not feel any group affiliation; of course, people felt connected to a family, a tribe, a religion, a city, or a ruler. However, the idea of a political community that we call a "nation," seen as the legitimate source of sovereignty, where all members are equal citizens, is unique to modernity. The birth of this idea is the product of a series of profound structural transformations and an intellectual revolution. 1.1. Political Legitimacy and Identity in the Pre-Modern World: In medieval and early modern Europe, the political structure was based on the intertwined and often conflicting claims of two universal authorities: the Papacy (spiritual authority) and the Holy Roman Empire (secular authority). The source of political legitimacy was God, and this legitimacy was transferred to the king through dynastic lineage and blood ties. A piece of land belonged not to the people living on it, but to the dynasty that seized it through inheritance, conquest, or marriage. The identity of an ordinary peasant was determined not by being a "Frenchman" or "German," but by the village they belonged to, the feudal lord they were subject to, and most importantly, their religion (Christianity). Different regions spoke different dialects and were subject to different customary laws. The king's subjects were the king's property; there was no direct political link between them and the state. In this world, the idea of a "nation," that is, a people living on a piece of land, sharing a common identity, and being the true owner of sovereignty, was both politically inconceivable and sociologically impossible. 1.2. The Birth of the Modern State and "Proto-Nationalism": This traditional order began to be gradually eroded from the 16th century onwards, particularly by the rising absolute monarchies in England and France. Kings started to centralize power to break the power of feudal lords and the Church, to collect taxes regularly, and to establish permanent armies. This process clarified the boundaries of the state, developed a common legal system (based on Roman Law), and most importantly, a specific dialect began to be standardized as the "official language" for the administration of affairs. The Edict of Villers-Cotterêts issued in France in 1539 was a giant step towards the standardization of the language and the establishment of the administrative infrastructure of national unity by ordering that all official transactions be conducted in French instead of Latin. This process, unconsciously, prepared the administrative, legal, and linguistic infrastructure of what would later be called a "nation." Although it did not yet rely on the sovereignty of the people, it strengthened the idea of creating a political unit loyal to the king, subject to a common law and administration, over a specific piece of land. Historians refer to this phenomenon as "proto-nationalism" or "state nationalism"; it is not nationalism itself, but the structural ground that would make its emergence possible. 1.3. Enlightenment Thought: The Invention of the "Nation" as the Source of Legitimacy: The real revolutionary break came with 18th-century Enlightenment thought. Enlightenment philosophers shifted the source of political legitimacy from God and the king to the "people" and the "nation" directly. This was a tremendous intellectual revolution that laid the foundation of modern political philosophy. John Locke (1632-1704) and the Consent of the Governed: Although he was not a nationalist, Locke's Two Treatises of Government established the philosophical foundation of the idea of popular sovereignty by arguing that the legitimacy of government is based on the consent of the governed and that this consent can be withdrawn. His definition of the right to property as a natural right made the individual a subject with inviolable rights against the state. Jean-Jacques Rousseau (1712-1778) and "General Will": Rousseau is the most important and direct precursor of the idea of nationalism. In his 1762 work The Social Contract , he argued that individuals come together through their free will to form a "general will" (volonté générale) that represents their common interests, and that sovereignty belongs to this people in an indivisible and inalienable manner. According to him, a legitimate state was a republic that expressed this general will. Rousseau elevated the concept of "citizen" (citoyen); a citizen was an active and virtuous political being who subordinated his private interests to the general will. He regarded love of the homeland as the highest virtue and developed the idea of a "civil religion" in which citizens identified themselves with the state and were connected to each other through public ceremonies and rituals. Rousseau's thoughts would directly inspire the Jacobins' nationalism during the radical phase of the French Revolution. Johann Gottfried von Herder (1744-1803) and "Volksgeist" (Spirit of the People): This original figure of the German Enlightenment gave nationalism a cultural and linguistic depth different from Rousseau's. Herder opposed the universalist and rationalist approach of the Enlightenment, arguing that humanity is composed of different "peoples" (Volk), each possessing a unique and valuable "spirit" (Volksgeist). According to him, the most important, even almost sacred, element that defines a nation is its language. Language is a living organism that carries a nation's way of thinking, history, pains, joys, songs, tales, and collective memory. Herder stated that each nation should follow its own unique path, asserting that universalist models are artificial and oppressive. He particularly called for the German people to return to their own language, folk songs, and history against the dominance of French culture in European courts. He viewed the nation not as a political project but as an organic, cultural entity that comes from the depths of history. Herder's ideas would become the foundational text for the cultural awakening movements of nations lacking political unity (Germans, Italians, Slavs) in Central and Eastern Europe throughout the 19th century. Johann Gottlieb Fichte (1762-1814) and "Addresses to the German Nation": The most important figure who transformed Herder's cultural nationalism into a political agitation was Fichte. In his famous Addresses to the German Nation delivered in Berlin under Napoleon's occupation in 1807-1808, he laid the groundwork for German nationalism. Fichte argued that Germans, unlike other European peoples, spoke a pure and uncorrupted language and thus were an original "first people" (Urvolk). According to him, the German nation not only shared a common culture but also had a historical mission to lead the moral and spiritual development of humanity. In these addresses, Fichte made a passionate call for nationalism aimed at creating a new German person through a national education system and uniting Germans under a single state. This is the first significant example showing how cultural nationalism can carry political and even expansionist potential. 1.4. The Great Catalyst: The French Revolution and the Nation's Assumption of Flesh and Blood (1789): The event that carried nationalism from theory to practice, from the books of philosophers to the streets, squares, and battlefields, is undoubtedly the French Revolution of 1789. While overthrowing the monarchy, the Revolution declared that the source of sovereignty was now the "French Nation." This is a turning point in world history. National Sovereignty and the Birth of the Citizen: The Etats-Généraux (Estates-General) convened in 1789 declared itself the "National Assembly," effectively proclaiming that sovereignty belongs to the nation. The Declaration of the Rights of Man and of the Citizen , adopted on August 26, 1789, linked this new understanding to universal principles. Article 3 of the declaration states, "The essence of all sovereignty resides essentially in the nation. No institution, no individual can exercise any authority that does not emanate expressly from the nation," thus establishing the fundamental axiom of modern politics. The king's "subjects" transformed into a "nation" of equal "citizens" who possess rights and duties. This was the descent of political legitimacy from heaven to earth. The Construction of National Unity and the Creation of the "Other": The Revolution not only destroyed the old regime but also actively aimed to create a new, singular, and indivisible French nation. This was a major project of cultural and political homogenization. Different regional identities, dialects (patois), feudal privileges, and the autonomy of the church within France were seen as obstacles to national unity and began to be systematically eradicated. Intense efforts were made for linguistic unity; Abbé Grégoire's famous report showed that the vast majority of the French population did not speak standard French and argued that dialects should be eliminated. In this process, the concept of "enemy of the nation" was invented. Those who opposed the values of the Revolution, including internal counter-revolutionaries (such as the peasants in the Vendée uprising) and external monarchies, were defined as "traitors" and "enemies," relegated to the status of the "other." This internal/external enemy distinction became one of the strongest tools for reinforcing national unity. The Revolution, with the slogan "freedom for the people," carried a universal claim for liberation. This gave French nationalism a character that aspired to be a model for all humanity, not just for
