Usos y Costumbres: Oaxaca's Indigenous Community Governance System

In most of the world, elections work like this: political parties nominate candidates, campaigns are run, voters cast secret ballots, and the candidate with the most votes takes office. In 417 of Oaxaca’s 570 municipalities — roughly 73% of the state — none of this happens. There are no political parties, no campaigns, no secret ballots, and often no candidates in the conventional sense. Instead, leaders are chosen through a system called usos y costumbres (uses and customs) — a form of indigenous community governance that predates the Spanish conquest and was formally recognized by Mexican law in 1995.

For international travelers, understanding usos y costumbres is not merely an academic exercise. It shapes the communities you visit, the festivals you attend, the markets you browse, and the interactions you have. It explains why certain villages maintain their traditions with fierce determination, why communal labor keeps roads and public buildings in good condition without government contracts, and why the concept of individual political ambition is viewed with deep suspicion in much of rural Oaxaca.

This article explains how the system works, why it has survived, and what it means for visitors.

What Is Usos y Costumbres?

At its core, usos y costumbres is a system of communal self-governance in which decisions affecting the community are made through open assemblies, leadership positions are rotated through a system of escalating civic and ceremonial responsibilities (the cargo system), and community members contribute unpaid labor (tequio) to collective projects.

The system varies significantly from community to community — the Zapotec communities of the Central Valleys practice it differently from the Mixtec villages of the highlands or the Mixe towns of the Sierra Norte — but the fundamental principles are consistent:

Authority rests with the assembly, not with individuals. The community assembly (asamblea comunitaria) is the supreme decision-making body. All adult community members (traditionally men, though women’s participation has been expanding) are expected to attend and participate.
Leaders serve, they do not rule. Holding a cargo (a position of community responsibility) is considered an obligation, not a privilege. Leaders are not paid, and the position often requires significant personal expenditure. Refusing a cargo when asked to serve is a serious breach of community norms.
Reciprocity is the organizing principle. Every community member is expected to contribute labor, time, and resources to the collective. In return, they receive the benefits of community membership: access to communal land, water, participation in festivals, and the social safety net of communal solidarity.

The Cargo System: A Ladder of Service

The sistema de cargos is the mechanism through which leaders are selected and community responsibilities are distributed. It is not an election in the Western sense — it is a system of rotating, escalating obligations that every community member is expected to fulfill over the course of their lifetime.

How It Works

A typical cargo system includes the following levels, though the specific names and responsibilities vary by community:

Level 1: Topil (Community Police/Messenger) Young men (usually in their late teens or early twenties) begin their civic life as topiles — community police, messengers, and general helpers. The topil serves for one year without pay, performing tasks assigned by the municipal president: delivering messages, maintaining order at public events, guarding community property at night, and running errands. This is the entry-level cargo — demanding, unglamorous, and mandatory.

Level 2: Committee Member After completing their topil service, community members serve on various committees: the school committee (comité de padres de familia), the water committee (comité de agua), the health committee, or the festival committee. Each service term is typically one year. These positions require time, organizational skill, and often personal financial contribution.

Level 3: Regidor (Council Member) Mid-career community members serve as regidores — members of the municipal council. They oversee specific areas of community life: education, public works, agriculture, commerce, or civil registry. This is a significant responsibility that requires regular attendance at council meetings, conflict resolution, and administrative competence.

Level 4: Síndico (Legal Representative) The síndico is the community’s legal representative in dealings with the state and federal government. This cargo requires knowledge of Mexican law, the ability to navigate bureaucracies, and the authority to represent the community’s interests in land disputes, resource conflicts, and administrative matters.

Level 5: Presidente Municipal (Municipal President) The highest cargo in the civil hierarchy. The municipal president serves as the community’s chief executive, presiding over assemblies, coordinating public works, managing the municipal budget (often minimal), and representing the community to the outside world. This position is demanding, unpaid, and typically requires the holder to set aside their own livelihood for one to three years.

The Ceremonial Side

Parallel to the civil cargo system is a ceremonial cargo system organized around the Catholic Church and traditional festivals. Ceremonial cargos include:

Mayordomo: The person responsible for organizing and financing the annual patron saint festival. This is one of the most expensive cargos — the mayordomo may spend 50,000-300,000 MXN ($2,700-$16,200 USD) or more on food, music, fireworks, decorations, and church maintenance. The expenditure is seen not as waste but as redistribution — the mayordomo’s wealth flows back to the community through the celebration.
Fiscal: Responsible for maintaining the church, organizing religious observances, and coordinating with the parish priest.
Capitán de festejos: Organizes specific elements of community celebrations: the music, the dances, the processions.

A fully “served” community elder — someone who has completed the full cycle of civil and ceremonial cargos over 20-30 years — is called a principal or caracterizado. Principals form a council of elders whose moral authority carries enormous weight in community decision-making. They do not command — they advise — but their advice is rarely ignored.

Tequio: The Obligation to Work

Tequio is the system of obligatory communal labor that operates alongside the cargo system. When the community needs a road repaired, a school building maintained, a water system constructed, or a public space cleaned, the municipal president calls a tequio. Every household is expected to send one adult to contribute labor for the designated period — typically one day, but sometimes longer for major projects.

Tequio is unpaid. Participants bring their own tools and food. The work is supervised by the relevant committee or regidor, and attendance is recorded. Households that fail to contribute without valid excuse face consequences: fines (usually 200-500 MXN / $11-$27 USD per missed day), suspension of community benefits (including access to communal water), or, in extreme cases, social ostracism.

The system is remarkably effective. Communities that practice tequio maintain their infrastructure without relying on government contractors. Roads are cleared, schools are painted, water systems are repaired, and public buildings are maintained through the collective labor of community members who have a direct stake in the results.

Tequio in Practice: What Travelers See

If you visit a small Oaxacan community and notice that the central plaza is immaculate, the church freshly whitewashed, the roads cleared of debris, and the public restrooms functional — this is not because of a generous municipal budget. It is tequio. The labor is contributed by the same people you see in the market, the mezcal distillery, and the comedor where you eat lunch.

Some community tourism programs in the Sierra Norte, including those in the Pueblos Mancomunados ecotourism network (Benito Juárez, Cuajimoloyas, Llano Grande, and others), invite visitors to participate in tequio as a cultural experience. This is an extraordinary opportunity — the chance to work alongside community members, share food, and understand the system from the inside.

The Assembly: Democracy Without Parties

The community assembly (asamblea comunitaria) is the supreme decision-making body in usos y costumbres municipalities. Major decisions — the selection of municipal authorities, the allocation of communal resources, the resolution of significant disputes, the planning of festivals, the approval of community projects — are made in the assembly.

How an Assembly Works

Assemblies are called by the municipal president, typically by announcing them through the community loudspeaker system (found in virtually every Oaxacan village) and by sending topiles to deliver personal notifications to each household. Attendance is obligatory for all adult community members (the definition of “adult” and “member” varies by community but typically means anyone over 18 who resides in the municipality).

The assembly meets in the municipal hall or, if the community is too large for indoor meetings, in the central plaza. The municipal president presides but does not control the discussion. Any community member can speak. Debates can be lengthy — assemblies that last six to eight hours are not unusual — and decisions are typically reached by consensus rather than majority vote, though voting by show of hands is used when consensus cannot be achieved.

The Selection of Authorities

In most usos y costumbres communities, the selection of municipal authorities follows a distinct process:

The outgoing administration identifies community members who have completed the prerequisite cargos and are eligible for the next level of service.
Names are proposed in the assembly — sometimes by the council of principals, sometimes by any community member.
The proposed candidates do not campaign. They may not even be present in the assembly when their name is raised.
The assembly discusses each candidate’s merits: their track record in previous cargos, their personal character, their financial stability (since the position is unpaid and often costly), and their knowledge of community affairs.
The assembly selects the new authority by consensus or vote.
The selected individual is notified and is expected to accept. Refusal is rare and carries social consequences.

This process produces leaders who are known intimately by the community, who have demonstrated competence through years of progressively responsible service, and who take office not because they sought power but because their community determined they were ready to serve.

Legal Recognition and Constitutional Status

Oaxaca was the first Mexican state to formally recognize usos y costumbres as a legitimate form of municipal governance. The key legal milestones:

1995: Oaxaca’s state electoral law was reformed to recognize municipalities governed by usos y costumbres, exempting them from the requirement to hold party-based elections.
1998: Mexico’s federal constitution was amended to recognize indigenous peoples’ right to “autonomy and self-determination” including the right to “elect their authorities according to their own norms, procedures, and practices.”
2001: A further constitutional reform recognized indigenous peoples’ rights to “apply their own normative systems in the regulation and resolution of internal conflicts.”

Today, 417 of Oaxaca’s 570 municipalities are officially classified as usos y costumbres, making Oaxaca the state with the largest number of indigenous self-governing communities in Mexico. The remaining 153 municipalities use the conventional party-based electoral system.

The legal recognition was a landmark achievement, but it has not eliminated tensions. The Mexican government’s oversight of usos y costumbres communities is limited, which provides genuine autonomy but also means that internal conflicts — particularly around women’s political participation, land disputes, and religious intolerance — are sometimes resolved in ways that conflict with federal human rights standards.

Criticisms and Ongoing Debates

Usos y costumbres is not without its critics, and honest engagement with the system requires acknowledging the debates:

Women’s Participation

Traditionally, many usos y costumbres communities restricted assembly participation and cargo eligibility to men. Women’s political participation has expanded significantly in recent decades — driven by both internal advocacy and external legal pressure — but the pace of change varies widely. Some communities have fully integrated women at all levels; others still limit women’s participation to the ceremonial cargo system or specific committees.

In 2014, the Oaxacan state congress mandated that usos y costumbres communities must guarantee women’s right to vote and hold office. Compliance has been uneven, and the tension between indigenous autonomy and gender equality remains one of the most actively debated issues in Oaxacan politics.

Religious Freedom

Some usos y costumbres communities require participation in Catholic festivals and ceremonies as a condition of community membership. Protestant converts and religious minorities have, in some cases, been expelled from communities or denied access to communal resources. The Mexican constitution guarantees freedom of religion, creating a direct conflict with community norms that treat religious participation as a civic obligation.

Migration and the Diaspora

The system assumes that community members live in the community. But migration — to Oaxaca City, to Mexico City, to the United States — has created a large diaspora population that maintains ties to their home communities but cannot fulfill cargos in person. Some communities have adapted by accepting financial contributions in lieu of physical presence; others require returned migrants to complete deferred cargos before regaining full community membership.

What Usos y Costumbres Means for Travelers

Understanding this system transforms how you experience the communities you visit:

When you attend a festival: The elaborate costumes, the mountains of food, the hours of music and fireworks — these are not sponsored by the government or a corporation. They are funded and organized by the mayordomo and the festival committee, community members fulfilling their cargos. Your attendance (and any purchase you make from food vendors, artisans, or musicians) directly supports this system.
When you visit a community tourism site: The well-maintained trails, clean cabins, and organized guide services in places like the Sierra Norte Pueblos Mancomunados are products of tequio and the cargo system. The guide who leads your hike may be fulfilling a tourism committee cargo. Community tourism accommodation typically costs 300-600 MXN ($16-$32 USD) per night, and guided hikes run 200-400 MXN ($11-$22 USD) per person.
When you are asked to contribute or participate: Some communities request a small cooperation fee (cooperación) from visitors — typically 20-50 MXN ($1-$3 USD). This is analogous to tequio — a small contribution to the collective. Pay it willingly.
When things seem inefficient or slow: Decisions in usos y costumbres communities are made by consensus in assemblies, not by individual authority. If your guide needs to check with the committee before allowing you to visit a particular site, or if a scheduled activity is delayed because an assembly is running long, this is the system functioning as designed. Patience and flexibility are appropriate responses.

Where to See Usos y Costumbres in Action

Sierra Norte (Pueblos Mancomunados)

The communities of Benito Juárez, Cuajimoloyas, Llano Grande, La Nevería, and Latuvi are governed by usos y costumbres and have developed one of Mexico’s most successful community tourism programs. Visitors can hike between communities on maintained trails (10-20 km / 6-12 miles between villages), stay in community-run cabins, eat meals prepared by local families, and observe the cargo system in action. The tourism program itself is managed through the cargo system — community members rotate through tourism committee positions.

Getting there: Colectivos from the Periférico terminal in Oaxaca City for 80-120 MXN ($4-$7 USD) per person. Cabin stays: 300-600 MXN ($16-$32 USD) per night.

Guelaguetza Festival

The annual Guelaguetza (last two Mondays in July) is itself an expression of usos y costumbres values. The word “guelaguetza” comes from Zapotec and refers to the system of reciprocal giving that underlies community solidarity. The dance delegations that perform at the festival are selected by their communities through the cargo and assembly system, and their participation is a form of communal service.

Any Village Festival

The most intimate way to observe usos y costumbres is to attend a fiesta patronal (patron saint festival) in a small community. These multi-day celebrations — which include processions, dances, communal meals, fireworks, and music — are organized and funded entirely through the cargo system. Ask at your hotel or local tourism office about upcoming festivals during your visit. In Oaxaca, there is almost always one happening somewhere within a day’s travel.

A System Worth Understanding

Usos y costumbres is not a quaint relic or a picturesque tradition maintained for tourists. It is a functioning system of governance that organizes the daily life of more than a million people across Oaxaca. It has survived the Aztec empire, the Spanish conquest, the Mexican Revolution, and the pressures of globalization because it provides something that externally imposed systems often do not: a form of governance in which every member has both obligations and a voice, in which leaders serve rather than rule, and in which the collective welfare takes precedence over individual ambition.

For travelers, understanding this system is the key to understanding why Oaxaca’s indigenous communities feel different from other tourist destinations. The cleanliness, the cultural coherence, the intensity of the festivals, the quality of the craftsmanship — these are not accidents. They are products of a social system that has been continuously refined for centuries.
