Mérida, Yucatán in the context of José María Pino Suárez

Campeche, officially the Free and Sovereign State of Campeche, is one of the 31 states which, with Mexico City, make up the 32 federal entities of Mexico. Located in southeast Mexico, it is bordered by the states of Tabasco to the southwest, Yucatán to the northeast, Quintana Roo to the east, by the Petén department of Guatemala to the south, and by the Orange Walk District of Belize to the southeast. It has a coastline to the west with the Gulf of Mexico. The state capital, also called Campeche, was declared a World Heritage Site in 1997. The formation of the state began with the city, which was founded in 1540 as the Spanish began the conquest of the Yucatán Peninsula. The city was a rich and important port during the colonial period, but declined after Mexico's independence. Campeche was part of the province of Yucatán, but split off in the mid-19th century, mostly due to political friction with the city of Mérida. Much of the state's recent economic revival is due to the discovery of petroleum offshore in the 1970s, which has made the coastal cities of Campeche and Ciudad del Carmen important economic centers. The state has important Mayan and colonial sites; however, these are not as well-known or visited as much as others in the Yucatán.

The state's executive power rests in the governor of Campeche and the legislative power rests in the Congress of Campeche, which is a unicameral legislature composed of 35 deputies.

Yucatán, officially the Free and Sovereign State of Yucatán, is one of the 31 states which, along with Mexico City, constitute the 32 federal entities of Mexico. It comprises 106 separate municipalities, and its capital city is Mérida.

Located on the northern part of the Yucatán Peninsula, it is bordered by the states of Campeche to the southwest and Quintana Roo to the southeast, with the Gulf of Mexico off its northern coast.

The Roman Catholic Archdiocese of Yucatán (Latin: Archidioecesis Yucatanensis) is an archdiocese of the Catholic Church based in Mérida, Yucatán, Mexico. The diocese of Campeche, the diocese of Cancún-Chetumal and the diocese of Tabasco are its suffragans. Its area is that of the state of the same name, covering an area of 17,204 square miles.

Uxmal (Yucatec Maya: Óoxmáal [óˑʃmáˑl]) is an ancient Maya city of the classical period located in present-day Mexico. It is considered one of the most important archaeological sites of Maya culture, along with Palenque, Chichen Itza and Calakmul in Mexico, Caracol and Xunantunich in Belize, and Tikal in Guatemala. It is located in the Puuc region of the western Yucatán Peninsula, and is considered one of the Maya cities most representative of the region's dominant architectural style. It was designated a UNESCO World Heritage Site along with the nearby ruins of Kabah, Sayil and Labna.

Uxmal is located 62 km south of Mérida, capital of Yucatán state in Mexico. Its buildings are noted for their size and decoration. Ancient roads called sacbes connect the buildings, and also were built to other cities in the area such as Chichén Itzá in modern-day Mexico, Caracol and Xunantunich in modern-day Belize, and Tikal in modern-day Guatemala.

Zócalo (Latin American Spanish pronunciation: [ˈsokalo]) is the common name of the main square in central Mexico City. Prior to the colonial period, it was the main ceremonial center in the Aztec city of Tenochtitlan. The plaza used to be known simply as the Plaza Mayor ("Main Square") or Plaza de Armas ("Arms Square"), and today its formal name is Plaza de la Constitución ("Constitution Square").

This name does not come from any of the Mexican constitutions that have governed Mexico but from the Cádiz Constitution, which was signed in Spain in the year 1812. Even so, it is almost always called the Zócalo today. Plans were made to erect a column as a monument to independence, but only the base, or zócalo (meaning "plinth"), was built. The plinth was buried long ago, but the name has lived on. Many other Mexican towns and cities, such as Oaxaca, Mérida, and Guadalajara, have adopted the word zócalo to refer to their main plazas, but not all.

Tinum Municipality (Yucatec Maya: "crippled numtzutzuy") is a municipality in the Mexican state of Yucatán containing 393.44 km (151.91 sq mi) of land and is located roughly 140 kilometres (87 mi) east of the city of Mérida.

Chicxulub Puerto (Spanish: [tʃikʃuˈlub ˈpweɾto] ) is a small coastal town in Progreso Municipality in the Mexican state of Yucatán. It is located on the Gulf of Mexico, in the northwestern region of the state about 8 km (5 mi) east of the city port of Progreso, the municipality seat, and 42 km (26 mi) north of the city of Mérida, the state capital. According to the INEGI census conducted in 2020, the port town had a population of 7,591 inhabitants.

Chicxulub Puerto is most famous for being near the geographic center of the Chicxulub crater, an impact crater discovered by geologists on the Yucatán Peninsula and extending into the ocean. It was created by the impact some 66 million years ago of the Chicxulub impactor, an asteroid or comet which caused the Cretaceous–Paleogene extinction event, which led to the extinction of all non-avian dinosaurs. Chicxulub Puerto lies almost exactly on the geographic center of the crater, and has used its notoriety for tourism, having opened tourist attractions such as a museum dedicated to the meteor impact.
