Political tribalism, the tendency to prioritize group identity and loyalty over broader societal interests, has deep historical roots, though its modern manifestations have become increasingly prominent in recent decades. While tribalism in its earliest forms can be traced back to ancient societies where kinship and communal bonds shaped governance, its political incarnation gained momentum during the rise of nation-states and ideological movements in the 18th and 19th centuries. The Industrial Revolution and the subsequent urbanization exacerbated divisions, as people sought belonging in an increasingly fragmented world. However, it was the 20th century, with its global conflicts, decolonization, and the advent of mass media, that political tribalism began to crystallize as a dominant force. The Cold War era further polarized societies along ideological lines, while the digital age of the 21st century has amplified tribalism through social media algorithms and echo chambers, making it a defining feature of contemporary politics. Understanding its origins requires examining the interplay of historical, cultural, and technological factors that have shaped human identity and allegiance.

Early human societies and tribalism
The roots of political tribalism can be traced back to the earliest human societies, where tribal structures were the primary form of social and political organization. These early societies, which emerged during the Paleolithic and Neolithic periods, were characterized by small, tightly-knit groups bound together by kinship, shared resources, and common survival strategies. Tribalism in this context was not a choice but a necessity for survival in a harsh and unpredictable environment. Within these tribes, decision-making was often collective, with elders or experienced members playing key roles in resolving disputes and making critical choices for the group. The sense of "us versus them" was innate, as tribes competed for limited resources like food, water, and territory. This early form of tribalism laid the foundation for the loyalty and solidarity that would later manifest in more complex political systems.
As human societies transitioned from hunter-gatherer lifestyles to settled agricultural communities during the Neolithic Revolution, tribal structures evolved but remained central to social organization. The establishment of permanent settlements led to the formation of larger tribes or chiefdoms, where leaders emerged based on their ability to manage resources, resolve conflicts, and ensure the group's survival. These leaders often derived their authority from perceived connections to the divine or ancestral traditions, reinforcing the tribal identity. Political decisions were still deeply intertwined with social and cultural norms, and loyalty to the tribe was paramount. Warfare between tribes became more organized, driven by the need to protect or expand agricultural lands, further entrenching the tribal mindset. This period marked the beginning of more formalized political structures, though they remained rooted in tribal loyalties.
The concept of tribalism in early human societies was also closely tied to identity and belonging. Membership in a tribe was typically determined by birth, and individuals were expected to prioritize the tribe's interests above their own. This collective identity fostered a strong sense of unity and mutual dependence, which was essential for survival in a world without modern institutions. Rituals, myths, and shared traditions played a crucial role in reinforcing tribal bonds, creating a cohesive social fabric. However, this exclusivity also sowed the seeds of conflict with outsiders, as tribes viewed those outside their group with suspicion or hostility. This dynamic would later influence the development of political tribalism, where group identity became a driving force in decision-making and conflict.
Early human societies also exhibited early forms of political competition and alliance-building, which can be seen as precursors to modern political tribalism. Tribes often formed alliances with neighboring groups to strengthen their position against common threats or to gain access to resources. Conversely, rivalries and conflicts were common, driven by competition for scarce resources or territorial disputes. Leaders who could effectively navigate these relationships and secure advantages for their tribe were highly valued, marking the beginnings of political strategy. These interactions highlight how tribalism was not merely a social phenomenon but also a political one, shaping the way power was exercised and maintained in ancient societies.
In summary, early human societies were fundamentally tribal in nature, with this structure serving as the bedrock of their social and political organization. The principles of loyalty, exclusivity, and collective decision-making that defined these tribes laid the groundwork for the political tribalism observed in later, more complex societies. While the forms and scales of tribalism have evolved over millennia, its origins in the survival strategies and social dynamics of early humans remain a critical factor in understanding its persistence in modern politics.

Rise of nation-states and identity
The rise of nation-states played a pivotal role in the emergence and evolution of political tribalism, as it reshaped identities and allegiances in profound ways. Prior to the modern era, political loyalties were often tied to local communities, feudal lords, or religious institutions. However, the consolidation of nation-states in the 17th to 19th centuries introduced a new framework for identity, centered around shared language, culture, history, and territory. This shift fostered a sense of collective belonging but also created boundaries that distinguished "us" from "them," laying the groundwork for tribalistic tendencies in politics.
The Treaty of Westphalia (1648) is often cited as a turning point, as it established the principle of state sovereignty and the idea that political authority derives from a unified national identity. This model encouraged the homogenization of diverse populations under a single national banner, often at the expense of minority groups. As nation-states sought to solidify their legitimacy, they promoted national myths, symbols, and narratives that reinforced a shared identity. While this fostered unity, it also sowed the seeds of exclusion, as those who did not fit the dominant cultural or ethnic mold were marginalized or viewed as outsiders.
The 19th century saw the rise of nationalism, which further intensified the link between nation-states and identity. Movements such as the unification of Germany and Italy were driven by the belief in a common heritage and destiny. However, this nationalism often took an ethnocentric turn, equating national identity with specific racial or cultural traits. This exclusionary mindset fueled political tribalism, as loyalty to the nation became a zero-sum game, where one’s gain was perceived as another’s loss. The rise of mass media and public education systems also played a role, as they disseminated nationalistic ideologies and reinforced the idea of a singular, unified identity.
The formation of nation-states also led to the creation of formal political institutions that codified and enforced these identities. Citizenship laws, for example, defined who belonged and who did not, often based on criteria such as ethnicity or birthplace. This institutionalization of identity further entrenched tribalistic thinking, as political allegiances became deeply intertwined with national belonging. In many cases, this led to the politicization of identity, where one’s political stance was seen as a reflection of their national loyalty rather than a matter of policy or principle.
Finally, the rise of nation-states set the stage for global conflicts that were, in many ways, clashes of tribal identities. World War I and World War II were fought along nationalistic lines, with each side claiming superiority and righteousness based on their unique identity. The aftermath of these conflicts further solidified the nation-state as the primary unit of global politics, but it also deepened divisions and rivalries. In this context, political tribalism became a dominant feature of international relations, as nations rallied their populations around shared identities to pursue their interests and assert their dominance. Thus, the rise of nation-states and the identities they fostered were central to the origins and persistence of political tribalism.

Colonialism's impact on tribal divisions
The roots of political tribalism are deeply intertwined with the legacy of colonialism, which played a significant role in exacerbating and manipulating tribal divisions. Before colonial powers arrived, many regions had diverse ethnic and tribal groups that coexisted with varying degrees of cooperation and conflict. However, colonial administrations often employed a "divide and rule" strategy, intentionally pitting tribes against one another to consolidate their own power. This approach not only deepened existing rivalries but also created new fault lines where none had previously existed. By favoring certain tribes with resources, recognition, or administrative roles, colonial powers fostered resentment and competition among others, laying the groundwork for enduring tribal divisions.
One of the most direct ways colonialism impacted tribal divisions was through the arbitrary drawing of borders. Colonial powers, particularly during the Scramble for Africa in the late 19th century, carved up territories without regard for existing tribal or ethnic boundaries. This resulted in the fragmentation of some tribes across multiple colonies, while others were forcibly grouped together within the same political entity. For example, the borders of modern-day Nigeria, drawn by British colonial authorities, lumped together over 250 ethnic groups, many of whom had historical rivalries. These artificial boundaries created a fertile ground for political tribalism, as groups competed for resources, representation, and dominance within the new colonial and post-colonial states.
Colonialism also imposed Western political systems and administrative structures that often clashed with traditional tribal governance models. In many cases, colonial powers dismantled indigenous systems of leadership and replaced them with centralized authorities that favored certain tribes or ethnic groups. This not only marginalized other tribes but also created a hierarchy of power that perpetuated inequality. For instance, in Kenya, the British colonial government favored the Kikuyu tribe in certain regions, granting them land and economic opportunities while disenfranchising others like the Maasai. Such preferential treatment sowed seeds of resentment that later manifested as political tribalism in post-independence struggles for power and resources.
Furthermore, colonialism introduced and amplified ideologies of racial and cultural superiority, which were often used to justify the exploitation of certain tribes over others. Missionaries, educators, and colonial administrators frequently portrayed Western culture as superior, undermining traditional tribal identities and values. This cultural erosion led to a loss of cohesion within tribes and, in some cases, prompted internal divisions as members sought to align themselves with colonial ideals to gain favor. The legacy of this cultural disruption continues to influence political tribalism today, as groups often cling to tribal identities as a means of resistance or assertion in the face of historical marginalization.
Finally, the economic policies of colonial powers often exacerbated tribal divisions by unevenly distributing resources and opportunities. Cash crop economies, mining operations, and infrastructure development were typically concentrated in areas inhabited by specific tribes, leaving others economically disadvantaged. This economic inequality became a source of political tension, as tribes competed for access to wealth and influence. In post-colonial contexts, these disparities have frequently been politicized, with tribal identities becoming proxies for economic and social grievances. Thus, colonialism's economic legacy remains a driving force behind the persistence of political tribalism in many former colonies.
In conclusion, colonialism's impact on tribal divisions was profound and multifaceted, creating a legacy that continues to shape political tribalism today. Through border demarcation, favoritism, cultural disruption, and economic exploitation, colonial powers not only deepened existing tribal rivalries but also manufactured new divisions. Understanding this historical context is crucial for addressing the roots of political tribalism and working toward more inclusive and equitable societies in regions affected by colonialism.

Modern political polarization roots
The roots of modern political polarization, often characterized by tribalism, can be traced back to a combination of historical, social, and technological factors that have intensified in recent decades. While tribalism in politics is not a new phenomenon—it has existed in various forms throughout history—its modern manifestation is shaped by contemporary dynamics. One key factor is the rise of identity politics, which began to gain prominence in the late 20th century. As societies became more diverse, political parties and movements increasingly framed issues around identity, whether based on race, religion, gender, or nationality. This shift encouraged people to align themselves with groups that shared their identities, fostering a "us vs. them" mentality that underpins political tribalism.
The restructuring of the political landscape in the United States during the late 20th century also played a significant role. The Republican and Democratic parties became more ideologically homogeneous, with conservatives consolidating in the GOP and liberals in the Democratic Party. This ideological sorting, often referred to as "partisan sorting," was accelerated by the realignment of the South, as white conservatives moved away from the Democratic Party following the civil rights era. By the 1990s, the parties were more polarized than ever, with less overlap in their policy positions and voter bases, creating fertile ground for tribalistic behavior.
The advent of the internet and social media in the 21st century further exacerbated political polarization. Platforms like Facebook, Twitter, and YouTube created echo chambers where individuals are exposed primarily to information that reinforces their existing beliefs. Algorithms prioritize content that generates engagement, often amplifying extreme or divisive viewpoints. This digital environment not only deepens ideological divides but also fosters a sense of tribal loyalty, as individuals are constantly reinforced by like-minded communities. Additionally, the rise of partisan media outlets, such as Fox News and MSNBC, has contributed to this dynamic by framing political issues in stark, adversarial terms.
Globalization and economic inequality have also fueled modern political tribalism. As economies became more interconnected, many communities experienced job losses and economic insecurity, leading to a backlash against elites and institutions perceived as out of touch. Populist movements on both the left and right emerged, often exploiting tribalistic rhetoric to mobilize supporters. This trend is evident in events like the Brexit vote in the UK and the election of Donald Trump in the U.S., both of which were driven by appeals to national or cultural identity in the face of perceived threats from globalization.
Finally, the erosion of trust in institutions has contributed to the rise of political tribalism. Declining faith in government, media, and other traditional authorities has left a void that political tribes have filled. People increasingly turn to their ideological groups for guidance and validation, further entrenching tribal loyalties. This distrust is often fueled by political leaders who undermine institutions for their own gain, creating a self-reinforcing cycle of polarization. Together, these factors have created a modern political landscape where tribalism thrives, shaping discourse and behavior in profound ways.

Media's role in tribalism amplification
The concept of political tribalism, where individuals strongly identify with their political group and often view opposing groups with hostility, has deep historical roots. While it’s challenging to pinpoint an exact starting point, scholars trace its origins to ancient societies where group identities were central to survival. However, in the modern context, the media has played a pivotal role in amplifying tribalism, particularly through the lens of political polarization. The rise of mass media in the 20th century and the subsequent explosion of digital platforms in the 21st century have transformed how political identities are formed and reinforced.
Media’s role in tribalism amplification is most evident in its tendency to prioritize sensationalism over balanced reporting. News outlets, both traditional and digital, often frame political issues in stark, binary terms—us versus them—to capture audience attention. This framing reinforces group identities by portraying one’s political tribe as morally superior and opponents as threats. For example, headlines that use inflammatory language or cherry-pick facts to support a particular narrative contribute to deepening divisions. Such practices exploit human psychology, as individuals are naturally inclined to seek information that confirms their preexisting beliefs, a phenomenon known as confirmation bias.
The advent of social media has further accelerated tribalism by creating echo chambers and filter bubbles. Algorithms on platforms like Facebook, Twitter, and YouTube prioritize content that aligns with users’ preferences, limiting exposure to diverse viewpoints. This not only reinforces existing beliefs but also radicalizes them, as users are constantly fed information that amplifies their political identity. Additionally, the viral nature of social media encourages the spread of misinformation and partisan content, which can exacerbate tribalistic tendencies. For instance, during election seasons, politically charged memes, videos, and posts often go viral, further entrenching divisions.
Another critical aspect of media’s role is its influence on political discourse. Pundits, commentators, and opinion leaders often use divisive rhetoric to rally their base, portraying political opponents as enemies rather than adversaries with differing perspectives. This combative style of communication trickles down to the public, fostering an environment where compromise is seen as weakness and loyalty to one’s tribe is paramount. Media outlets that align with specific political ideologies further contribute to this dynamic by consistently presenting narratives that demonize the other side, leaving little room for nuanced discussion.
Finally, the 24-hour news cycle and the pressure to generate constant content have led to a focus on conflict rather than cooperation. Media organizations often highlight controversies and scandals, which, while engaging, contribute to a narrative of perpetual conflict. This constant exposure to adversarial content normalizes tribalistic behavior, making it seem like the only way to engage in politics. As a result, the media not only reflects societal divisions but actively shapes them, playing a central role in the amplification of political tribalism. Understanding this dynamic is crucial for addressing the root causes of polarization and fostering a more constructive political discourse.
