Separated to the north by Puebla and Veracruz, to the east by Chiapas, to the west by Guerrero and to the south by the Pacific Ocean, Oaxaca is an extremely geographically fragmented state and can be described as culturally diverse. The steep spurs and foothills of the Sierra Madre del Sur, Sierra Norte and Sierra de Oaxaca cover two-thirds of the state. These topographical features, combined with very short coastal plains and the low Isthmus of Tehuantepec, have assisted in causing isolation and conserving a splendid mosaic of indigenous languages and customs for thousands of years.
History
Oaxaca: The territory that is currently Oaxaca was a centre of early Mesoamerican civilisation. The Zapotecan city of San Jose Mogote was the largest settlement of the Oaxaca Valley between c.1500 and c.500 B.C. and was a political, economic and religious centre to the nearby villages. This early urban community formed the basis of Monte Albán, one of the first great cities in Mesoamerica and the capital of the Zapotec culture over a millennial period.
After the bloom of the Zapotecs, the Mixtec civilisation appeared as a very strong power in both the western and southern parts of the modern-day Oaxaca. Both cultures laid monumental architecture, calendrical and writing systems, and built trade networks. The archaeological sites in areas like Mitla and the ruins of Yagul once attest to the complexity and sophistication of their pre-Hispanic societies, which survived the conquest and the colonial upheaval.
Oaxaca was absorbed into the Viceroyalty of New Spain after the Aztec Empire was conquered by the Spaniards in the first years of the 16th century. The colonial dominance changed ownership of land, religion, and local administration, but did not achieve full assimilation, as indigenous people in the highlands fought against it. After the independence of Mexico in 1821, Oaxaca itself was made a state of the new federal republic on December 21, 1823, complementing its position as one of the original members of the Mexican union.
Oaxaca has been a central actor in the politics and social movements of the 20th and 21st centuries in the country. It had given birth to Benito Juárez, the first indigenous Mexican president, who launched the liberal reforms that transformed the republic. Above the national level is the local level, where more than 3/4 of the 570 municipalities in Oaxaca are governed by usos y costumbres, which implies a form of customary government that gives communities the right to choose their own authority and stay true to the legal legacy of their ancestors.
Culture
Oaxaca is one of the richest indigenous cultures in the world, where it is well known that the living indigenous culture exists. There are sixteen officially recognised indigenous groups of people, with the highest number being the Zapotecs and the Mixtecs. The rural communities have survived comparatively well in preserving their languages, rituals and artisanal practices compared to other areas due in part to the isolated nature of the Sierra Madre Ranges as well as the cultural strength of their communities.
Oaxacan people base their cultural identity on artisan crafts. The pottery in the black clay of San Bartolo Coyotepec, rugs and textiles that are hand-woven in Teotitlan del Valle, and wooden animal figures that are painted in beautiful colours called alebrijes are all created in the region of the Central Valleys by artisans. The seashores add palm weaving of fine quality and gourds in the form of utility and ornamental articles. Such crafts not only preserve the economy of locality but have acquired a global identity as well, resulting in the revival of pride in indigenous artistry.
Festivals and cuisines also make life lively in Oaxaca. Each year, a festival known as the Guelaguetza, which brings together indigenous dance troupes of the state, commemorates the agrarian cycle and social networks as a way of performing rituals with dance, music and costume. In the meantime, Oaxacan food, known internationally as the famous seven moles, tlayudas (big grilled tortilla), chapulines (roasted grasshoppers) and the mezcal par excellence, has undergone several centuries of culinary mixture, with the pre-Hispanic cuisine combined with the Spanish and African ones.
The Catholic frameworks are commonly combined with profound pre-Columbian cosmologies in religion and popular beliefs in Oaxaca. Day of the Dead festivities reflect this syncretism in the building of elaborate ofrendas to honour departed relatives, where marigolds are used in floral bouquets and painted skulls, and offerings of food and drink are included. Churches, convents, and town squares have retained an element of the centre of community life, and this demonstrates how the colonial architecture and the indigenous spirituality are in a coexisting dialogue.
Language
Oaxaca is among the states that are linguistically diverse in Mexico. About four in five residents of the place speak an indigenous language as their first. There are at least 16 officially recognised groups of native peoples in the state, of Oto-Manguean, Mixe-Zoquean, and Mayan languages. The most popular of these include Zapotec, Mixtec, Mazatec, Chinantec and Mixe with several regional dialects and variations of each.
There has been an increasing impetus to save and restore these languages in the last several decades, through bilingual education, community radio stations, and cultural projects aimed at making them more robust in cross-generational transmission. Through federal and state laws, indigenous languages are now recognised as national languages along with Spanish, and they are given equal status in the courts, schools and the government administration. This is to make sure that the tapestry of speech in Oaxaca will exist well into the 21st century.
Geography
The state is about 93,757 square kilometres, and therefore it is the fifth-largest state in Mexico. The terrain is mainly characterised by the intersection of 3 major mountain systems, i.e. the Sierra Madre del Sur (south of the state), the Sierra Norte (northern part of the state), and the Sierra de Oaxaca (central portion), which covers more than 80 per cent of the state. The result of these rugged ranges includes steep escarpments, deep canyons and high-altitude plateaus, which range between 500 meters in the low valleys to mountain peaks above 3,700 meters above sea level.
The Valley of Oaxaca in the middle part of the state is made up of three basins, entirely connected, as Etla, Tlacolula and Miahuatl, that are located in a range of altitude between 1,500 and 1,800 meters above sea level. These valleys are bounded by ridges that cause cooler mountain air to flow downslope, forming a cooler microclimate great suited to the growing maize, beans and agaves. East, the Isthmus of Tehuantepec lies as a low corridor of land less than 200 meters elevated above sea level, with heavy northerly winds blowing across the land, and thus the region has been attractive to wind-power generation.
Due to uneven relief, Oaxaca has a hydrology. Significant rivers like the Papaloapan and its split Papaloapan River, Riogrande, Río Verde and the coastal rivers like the Tehuantepec, Copalita, and Mixteco replace the sides of the northern rocky slopes towards the Gulf of Mexico, and the strategic short coast legal rivers dash southward into the Pacific. There are many rain season rivers with narrow valleys, and highland springs with lasting rivers flowing to nourish the coffee plant gardens and cloud forests. There are also a few shallow lakes and lagoons in intermontane valleys that are vital to migratory birds and local fisheries.
Climatically, Oaxaca ranges between being humid tropical along the coast, where rainfall may reach over 2,000 mm in a year and the temperature readings are often more than 30 °C most of the time, to temperate and even alpine in the high sierras, where winter can bring frost. June to October is the rainy period, and the orographic lift maintains green vegetation on windward slopes; the valleys on the lee side are relatively dry. It is with this huge variation in rainfalls that the impressive mosaic of ecosystems found in the state is exhibited.
The Oaxaca Ecoregions include such ecoregions as mangrove and tropical dry forest in the coastal plain, mesic and cloud forests in the mid elevations. Sierra Madre and Sierra Norte preserve huge pine-oak forests, which are also one of the most biodiverse temperate forests on the planet. In this case, orchids, bromeliads, and ferns are endemic and flourish in constant mist; gaps clear under the canopy promote young pines and oaks. Due to a lack of rain, tropical thorn scrub and species of cactus grow in the rain-shadowed lower slopes and adjust with the extended dry seasons.
The coast of Oaxaca has coral reefs, sea turtles, and migrating whales along the coastline between Huatulco and Puerto Escondido. Narrow beaches are cushioned by fringing reefs and produce tranquil areas used as lagoons to obtain shrimp, clams and octopus by fishing communities. Seasonal upwellings occur offshore, nourishing its marine food web and drawing pelagic species upon which sport fishermen capitalise and upon which artisanal processes have been utilised since centuries-old fisheries.
