Isthmus of Tehuantepec in the context of "Isthmian script"

Minatitlán is a city in the Mexican state of Veracruz. It is located in the southeastern part of the state, in the Olmeca region, to the north of the Isthmus of Tehuantepec, along the Coatzacoalcos River.

In 2010 the greater metropolitan area had a population of 356,020.

Moctezuma Xocoyotzin (c. 1466 – 29 June 1520), retroactively referred to in European sources as Moctezuma II, and often simply called Montezuma, was the ninth emperor of the Aztec Empire (also known as the Mexica Empire), reigning from 1502 or 1503 to 1520. Through his marriage with Queen Tlapalizquixochtzin of Ecatepec, one of his two wives, he was also the king consort of the altepetl.

The first contact between the indigenous civilizations of Mesoamerica and Europeans took place during his reign. He was killed during the initial stages of the Spanish conquest of the Aztec Empire when Hernán Cortés, the Spanish conquistador, and his men seized the Aztec capital of Tenochtitlan. During his reign, the Aztec Empire reached its greatest size. Through warfare, Moctezuma expanded the territory as far south as Xoconosco in Chiapas and the Isthmus of Tehuantepec, and incorporated the Zapotec and Yopi people into the empire. He changed the previous meritocratic system of social hierarchy and widened the divide between pipiltin (nobles) and macehualtin (commoners) by prohibiting commoners from working in the royal palaces.

The geography of Mexico describes the geographic features of Mexico, a country in the Americas. Mexico is located at about 23° N and 102° W in the southern portion of North America. From its farthest land points, Mexico is a little over 3,200 km (2,000 mi) in length. Mexico is bounded to the north by the United States (specifically, from west to east, by California, Arizona, New Mexico, and Texas), to the west and south by the Pacific Ocean, to the east by the Gulf of Mexico, and to the southeast by Belize, Guatemala, and the Caribbean Sea. The northernmost constituent of Latin America, it is the most populous Spanish-speaking country in the world. Mexico is the world's 13th largest country, three times the size of Texas.

Almost all of Mexico is on the North American Plate, with small parts of the Baja California Peninsula in the northwest on the Pacific and Cocos Plates. Some geographers include the portion east of the Isthmus of Tehuantepec including the Yucatán Peninsula within North America. This portion includes Campeche, Chiapas, Tabasco, Quintana Roo, and Yucatán, representing 12.1 percent of the country's total area. Alternatively, the Trans-Mexican Volcanic Belt may be said to delimit the region physiographically on the north. Geopolitically, Mexico is generally not considered part of Central America. Politically, Mexico is divided into thirty-two states.

The Bay of Campeche (Spanish: Bahía de Campeche), or Campeche Sound, is a bight in the southern area of the Gulf of Mexico, forming the north side of the Isthmus of Tehuantepec. It is surrounded on three sides by the Mexican states of Campeche, Tabasco and Veracruz. The area of the bay is 6,000 square miles (16,000 km) and maximum depth of the bay is approximately 180 feet (55 m). It was named by Francisco Hernández de Córdoba and Antón de Alaminos during their expedition in 1517.

The Canadian Rockies (French: Rocheuses canadiennes) or Canadian Rocky Mountains, comprising both the Alberta Rockies and the British Columbian Rockies, is the Canadian segment of the North American Rocky Mountains. It is the easternmost part of the Canadian Cordillera, which is the northern segment of the North American Cordillera, the expansive system of interconnected mountain ranges between the Interior Plains and the Pacific Coast, that runs northwest–southeast from central Alaska to the Isthmus of Tehuantepec in Mexico.

Canada officially defines the Rocky Mountains system as the mountain chains east of the Rocky Mountain Trench extending from the Liard River valley in northern British Columbia to the Albuquerque Basin in New Mexico, not including the Mackenzie, Richardson and British Mountains/Brooks Range in Yukon and Alaska (which are all included as the "Arctic Rockies" in the United States' definition of the Rocky Mountains system). The Canadian Rockies, being the northern segment of this chain, is thus defined as comprising the central-eastern section of the North American Cordillera, between the Prairies of Alberta and the Liard Plain of northeastern British Columbia to the east and the Interior Mountains/Plateau and Columbia Mountains to the west. It is divided into the Northern Rockies (which is further subdivided into the Muskwa and Hart Ranges) and Continental Ranges, separated by the McGregor River valley, the McGregor Pass and the Kakwa River valley.

The Coatzacoalcos is a large river that feeds mainly the south part of the state of Veracruz; it originates in the Sierra de Niltepec and crosses the state of Oaxaca in the region of the Isthmus of Tehuantepec, flowing for 325 kilometres (202 miles) toward the Gulf of Mexico. Tributaries include El Corte, Sarabia, Jaltepec, Chalchijalpa, El Chiquito, Uxpanapa, and Calzadas. The merging of all these rivers creates one of the largest current flows in the entire region. Two-thirds of the streams are navigable.

Juan de Grijalva's 1518 expedition encountered the river. Hernán Cortés sent Diego de Ordaz to explore the river as a possible port.

Tlacolula de Matamoros is a city and municipality in the Mexican state of Oaxaca, about 30 km from the center of the city of Oaxaca on Federal Highway 190, which leads east to Mitla and the Isthmus of Tehuantepec. It is part of the Tlacolula District in the east of the Valles Centrales Region.

The city is the main commercial center for the Tlacolula Valley area, and best known for its weekly open air market held on Sundays. This market is one of the oldest, largest and busiest in Oaxaca, mostly selling food and other necessities for the many rural people which come into town on this day to shop. The city is also home to a 16th-century Dominican church, whose chapel, the Capilla del Señor de Tlacolula, is known for its ornate Baroque decoration and a crucifix to which have been ascribed many miracles. Outside the city proper, the municipality is home to the Yagul archeological site. and a number of a group of one hundred caves and rock shelters which document the pre-historic transition of people from hunting and gathering to agriculture based on the domestication of corn and other plants.

Isthmus-34 Light is a sour crude oil produced in Mexico mainly in the Campeche zone, in the Gulf of Mexico along with the extraction centers in Chiapas, Tabasco, and Veracruz. The name derives from the nearby Isthmus of Tehuantepec. Before 2017, the oil was a component of the OPEC Reference Basket (despite Mexico's not being a part of OPEC). It has the following characteristics:
