This book traces the long and contested history of religious authority and secular power in Mexico, from the establishment of colonial missions to the upheavals that culminated in the Cristero War. At stake across these centuries were not only property and legal jurisdiction but the everyday moral frameworks through which communities understood family life, education, and political belonging. By following disputes over land, schooling, and the regulation of public devotion, this study shows how religious life was both a resource and a battleground for competing visions of nationhood.

My central argument is that anticlericalism and secularization cannot be understood solely as top-down programs imposed by elites; they were also shaped, resisted, and reimagined at the local level. Clergy acted as political brokers and community leaders, while reformers—liberal and revolutionary— deployed law, rhetoric, and sometimes force to remake institutions that had been central to social order. Conversely, popular faith practices adapted to, and in turn reshaped, the terms of reform. The resulting conflicts produced a Mexican public in which religion and statecraft were continually entangled rather than neatly separated.

Methodologically, this volume combines legal analysis with microhistorical case studies. Court records, parish registers, municipal minutes, newspaper debates, and personal correspondence are read together to show how national reforms played out in particular towns, haciendas, and mission districts. Several chapters foreground regional case studies—Puebla, Jalisco, and Oaxaca among them—to demonstrate variation in patterns of clerical influence and anticlerical mobilization. These local narratives are used to test broader claims about secularization and to highlight the uneven geography of reform.

Historiographically, the book intervenes in debates about liberalism, revolution, and the formation of the Mexican state. Rather than treating secularization as a single, teleological process, I emphasize its episodic nature: moments of intense legal reform alternated with periods of negotiated toleration or outright conflict. The Cristero War, which receives extended treatment here, is presented both as a culmination of long-term tensions and as a catalyst that recast memory, martyrdom, and political identity well into the twentieth century.

Organization follows a roughly chronological and thematic progression. The opening chapters reconstruct colonial missions, parish structures, and Bourbon-era reforms that set the institutional foundations for later disputes. Middle chapters trace nineteenth-century liberal reforms, the secularization of property and education, and the social consequences of expulsions and anticlerical statutes. The final chapters examine revolutionary politics, the juridical consolidation of secularism, and the regional and national responses that produced the Cristero conflict and its lasting legacies.

Ultimately, this book aims to illuminate how religion shaped Mexican public life in ways that outlasted individual regimes. It argues for a more nuanced understanding of anticlericalism—not as simple hostility to belief, but as a contested project involving law, memory, regional practice, and competing claims to moral authority. By weaving together legal moments and local stories, I hope to show how the tug-of-war between church and state was central to the making of modern Mexico.

The arrival of the Spanish in the Americas in the late fifteenth and early sixteenth centuries was, for all its economic and political motivations, fundamentally a religious enterprise. Conquistadors carried not only swords and flags but also crosses, viewing their territorial expansion as a divinely sanctioned mission to spread the Catholic faith. This intertwined nature of conquest and evangelization profoundly shaped the future of what would become Mexico, embedding the Church deep within the colonial state and laying the groundwork for centuries of conflict and cooperation. The early colonial period, particularly the establishment of missions, was a crucial crucible where indigenous cosmologies clashed with European Christianity, creating a complex and often contradictory spiritual landscape.

From the outset, the Spanish Crown asserted a unique form of authority over the Church in its new territories, known as the Patronato Real or Royal Patronage. This was no mere suggestion; it was a comprehensive legal and administrative framework that granted the Spanish monarchs unprecedented control over ecclesiastical affairs. The Pope, recognizing the immense logistical challenges and the zealous commitment of the Spanish to conversion, ceded significant powers. The Crown gained the right to nominate bishops and other high-ranking clergy, to approve the construction of churches and monasteries, and even to collect tithes—a tax traditionally levied by the Church. This royal prerogative meant that the Church in New Spain was, in many respects, an extension of the state, its hierarchy intertwined with the colonial administration. This intimate connection would prove to be a double-edged sword: it provided the Church with immense resources and protection but also subjected it to state interests and interventions, setting a precedent for future clashes over autonomy.

The initial wave of evangelization was spearheaded by mendicant orders: Franciscans, Dominicans, and Augustinians. These friars, often driven by intense spiritual fervor and an almost utopian vision of creating a new Christian society, fanned out across the vast and diverse territories of New Spain. Their strategies for conversion varied, but a common thread was the establishment of missions. These were not simply churches; they were often self-sufficient communities designed to transform indigenous populations into loyal Catholic subjects. Missions served as centers for religious instruction, agricultural training, and often, rudimentary Spanish education. They were, in essence, laboratories for colonial social engineering, attempting to reorder indigenous life according to European norms.

The Franciscans, in particular, were prominent in the early phases, establishing a strong presence in central Mexico and later expanding into the northern frontiers. Their approach often emphasized collective conversion and the dramatic spectacle of the new faith. They built monumental churches, frequently atop pre-Hispanic religious sites, symbolically asserting the triumph of Christianity over indigenous deities. Mass baptisms were common, sometimes involving thousands of individuals, though the depth of understanding among the newly baptized was often questionable. For many friars, the sheer act of baptism, even without full comprehension, was a crucial first step in bringing souls into the Christian fold. This focus on outward conformity, while perhaps necessary given the scale of the task, often masked a persistent syncretism beneath the surface.

The Dominicans, arriving shortly after the Franciscans, also played a significant role, particularly in regions like Oaxaca. They were known for their rigorous intellectual training and their commitment to doctrinal purity. Their missions often prioritized thorough instruction in Christian tenets, sometimes through the creation of catechisms in indigenous languages. The Augustinians, similarly, focused on education and the establishment of schools within their mission complexes, aiming to cultivate a new generation of indigenous leaders who could articulate and spread the Christian message. While all three orders shared the common goal of conversion, their distinct approaches contributed to the mosaic of religious practices that emerged across New Spain.

The challenge of converting diverse indigenous populations, speaking hundreds of different languages and adhering to deeply entrenched spiritual traditions, was immense. Friars often struggled with linguistic barriers, leading to the rapid development of linguistic studies and the creation of grammars and dictionaries for indigenous languages. This effort, while driven by evangelization, also inadvertently preserved aspects of indigenous cultures that might otherwise have been lost. However, the friars also confronted sophisticated indigenous religious systems, replete with complex cosmologies, rituals, and deities. Rather than simply replacing these beliefs, Christianity often became intertwined with them, creating a unique form of religious syncretism that continues to characterize Mexican Catholicism today.

One of the most powerful tools in the missionaries’ arsenal was the visual and performative aspect of Catholicism. Grand processions, dramatic passion plays, and the veneration of richly adorned saints' images captivated indigenous audiences. These spectacles often resonated with pre-Hispanic traditions that also featured elaborate rituals and iconography. The introduction of new saints and Marian devotions, in particular, provided new focal points for worship that sometimes paralleled or even absorbed existing indigenous deities. The Virgin of Guadalupe, whose apparition is traditionally dated to 1531, became a particularly potent symbol, embodying a blend of indigenous and European spiritual elements and quickly becoming a cornerstone of Mexican religious identity.

Beyond the spiritual realm, missions were also economic and social entities. They controlled vast tracts of land, often worked by indigenous labor, producing goods ranging from agricultural products to textiles. These economic activities were intended to make the missions self-sufficient and to fund their evangelical work, but they also integrated the missions deeply into the colonial economy. The friars often acted as administrators, judges, and even military leaders, particularly on the frontier, blurring the lines between spiritual and temporal authority. This accumulation of economic and political power by the missions would later become a point of contention, as the colonial state and later the independent Mexican state sought to curb the Church’s extensive holdings and influence.

The process of conversion was rarely straightforward or entirely voluntary. While some indigenous communities embraced aspects of Christianity, others resisted, sometimes violently. Rebellions against mission authority, though often localized, were not uncommon, demonstrating the ongoing struggle for religious and cultural autonomy. Even in seemingly converted communities, elements of pre-Hispanic religious practices often persisted underground or in modified forms. The friars themselves frequently expressed frustration at what they perceived as the superficiality of indigenous conversion, lamenting the persistence of "idolatry" and superstition. This ongoing tension between imposed Christianity and resilient indigenous beliefs would be a recurring theme throughout Mexican history.

The missions on the northern frontiers of New Spain, stretching into what is now the southwestern United States, faced even greater challenges. Here, indigenous populations were often nomadic or semi-nomadic, making permanent settlement and systematic evangelization more difficult. The friars, particularly the Franciscans, worked alongside soldiers to establish presidios (forts) and missions, creating a network of outposts designed to secure the frontier and convert the local populations. These missions often served as defensive strongholds against hostile indigenous groups and encroaching foreign powers. The experience of conversion in these frontier regions was often more coercive, driven by the immediate needs of colonial expansion and security.

The legal framework for the treatment of indigenous peoples, as outlined by the Spanish Crown, was theoretically protective, viewing them as new converts and subjects deserving of special consideration. However, in practice, the reality was often harsh. The encomienda system, which granted Spanish settlers control over indigenous labor and tribute in exchange for their evangelization, often devolved into exploitation. While the mendicant orders frequently championed the rights of indigenous peoples against the abuses of encomenderos, their own mission systems, while perhaps less overtly exploitative, still imposed a profound cultural and social transformation. The debate over the proper treatment and status of indigenous populations, and the role of the Church in mediating this, would continue to animate colonial society.

The legacy of the colonial missions is undeniably complex. On the one hand, they were instruments of colonial power, facilitating the subjugation and cultural assimilation of indigenous peoples. On the other hand, they were also centers of cultural exchange, where European knowledge, technologies, and artistic traditions were introduced, and where, paradoxically, aspects of indigenous languages and cultures were sometimes preserved. The architectural grandeur of many mission churches, the artistic achievements they fostered, and the enduring spiritual traditions they helped to establish are all testaments to their profound and lasting impact. The missions laid the foundational religious and institutional landscape of New Spain, a landscape that would continually be contested and reshaped in the centuries that followed, but whose initial contours were irrevocably drawn by the zealous friars and their ambitious project of conversion.
