Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Mexico, officially the United Mexican States, is a federal republic in the southern half of North America. It is bordered to the north by the United States, to the south and west by the Pacific Ocean, to the southeast by Guatemala, Belize, and the Caribbean Sea, and to the east by the Gulf of Mexico. Covering almost two million square kilometers, Mexico is the sixth largest country in the Americas by total area, Mexico is a federation comprising 31 states and a federal district that is also its capital and most populous city. Other metropolises include Guadalajara, Monterrey, Puebla, Toluca, Tijuana, pre-Columbian Mexico was home to many advanced Mesoamerican civilizations, such as the Olmec, Toltec, Teotihuacan, Zapotec, Maya and Aztec before first contact with Europeans. In 1521, the Spanish Empire conquered and colonized the territory from its base in Mexico-Tenochtitlan, Three centuries later, this territory became Mexico following recognition in 1821 after the colonys Mexican War of Independence. The tumultuous post-independence period was characterized by instability and many political changes. The Mexican–American War led to the cession of the extensive northern borderlands, one-third of its territory. The Pastry War, the Franco-Mexican War, a civil war, the dictatorship was overthrown in the Mexican Revolution of 1910, which culminated with the promulgation of the 1917 Constitution and the emergence of the countrys current political system. Mexico has the fifteenth largest nominal GDP and the eleventh largest by purchasing power parity, the Mexican economy is strongly linked to those of its North American Free Trade Agreement partners, especially the United States. Mexico was the first Latin American member of the Organisation for Economic Co-operation and Development and it is classified as an upper-middle income country by the World Bank and a newly industrialized country by several analysts. By 2050, Mexico could become the fifth or seventh largest economy. The country is considered both a power and middle power, and is often identified as an emerging global power. Due to its culture and history, Mexico ranks first in the Americas. Mexico is a country, ranking fourth in the world by biodiversity. In 2015 it was the 9th most visited country in the world, Mexico is a member of the United Nations, the World Trade Organization, the G8+5, the G20, the Uniting for Consensus and the Pacific Alliance. Mēxihco is the Nahuatl term for the heartland of the Aztec Empire, namely, the Valley of Mexico, and its people, the Mexica and this became the future State of Mexico as a division of New Spain prior to independence. It is generally considered to be a toponym for the valley became the primary ethnonym for the Aztec Triple Alliance as a result. After New Spain won independence from Spain, representatives decided to name the new country after its capital and this was founded in 1524 on top of the ancient Mexica capital of Mexico-Tenochtitlan

States of Mexico
–
The United Mexican States is a federal republic composed of 31 states and Mexico City. According to the Constitution of 1917, the states of the federation are free, each state has its own congress and constitution. Mexico City is currently being reformed to have the rights of a state. The states of the Mexican Federation are free, sovereign, autonomous and they are free to govern themselves according to their own laws, each state has a constitution that cannot contradict the federal constitution, which covers issues of national competence. Since states have autonomy, each has its own civil and penal codes. In addition, the federation makes up a constituency in which 32 senators are elected by the method of proportional representation, Federal Deputies, however, do not represent the states, but rather the citizens themselves. The Chamber of Deputies and the Senate together comprise the Congress of the Union, the states are internally divided into municipalities. Each municipality is autonomous in its ability to elect their own council, the council is headed by a mayor elected every 3 years with no possibility of immediate reelection. Each municipality has a composed of councilors in terms of population size. The council is responsible, in most cases, to all utilities required for its population. This concept, which arises from the Mexican Revolution, is known as a free municipality. In total there are 2438 municipalities in Mexico, the state with the highest number of municipalities is Oaxaca, with 570, Mexico City has a special status within the federation, being a federal district. Until January 2016, Mexico City was officially called Federal District and it is the seat of government of the Union and the capital of the United Mexican States. Mexico City was separated from the State of Mexico, of which it was the capital, on November 18,1824, as such, it did not belong to any state in particular but to all. Therefore, it was the president of Mexico, in representation of the federation, with full autonomy, Mexico City would have its own constitution – it previously had only an organic law called Statute of Autonomy – and its boroughs became municipalities. Until the ratification of Mexico Citys constitution, it is divided for administrative purposes into 16 delegacionesor boroughs. *Mexicos post agency, Correos de México, does not offer an official list, various competing commercially devised lists exist. The list here reflects choices among them according to these sources, on September 27,1821, after three centuries of Spanish rule, Mexico gained independence

Tamaulipas
–
Tamaulipas, officially the Free and Sovereign State of Tamaulipas, is one of the 31 states which, with Mexico City, comprise the 32 Federal Entities of Mexico. It is divided into 43 municipalities and its capital city is Ciudad Victoria, the capital city was named after Guadalupe Victoria, the first President of Mexico. It is located in Northeastern Mexico and it is bordered by the states of Veracruz to the southeast, San Luis Potosí to the southwest and Nuevo León to the west. To the north, it has a 370 km stretch of the U. S. –Mexico border along the state of Texas and this state is known to be both a territorial struggle for the Gulf Cartel and the Los Zetas. The name Tamaulipas is derived from Tamaholipa, a Huastec term in which the tam- prefix signifies place, there is no scholarly agreement on the meaning of holipa, but high hills is a common interpretation. Another explanation of the name is that it is derived from Ta ma holipam. In addition to the city, Ciudad Victoria, the states largest cities include Reynosa, Matamoros, Nuevo Laredo. The area known as Tamaulipas has been inhabited for at least 8,000 years, several different cultures have come and gone during that period. Tamaulipas was originally populated by the Olmec people and later by Chichimec and Huastec tribes, between 1445 and 1466, Mexica armies commanded by Moctezuma I Ilhuicamina conquered much of the territory and transformed it into a tributary region for the Mexica empire. However, the Aztecs never fully conquered certain mostly nomadic indigenous groups in the area, although Hernán Cortés conquered the Aztecs rather quickly, it took a gradual process for Spain to subjugate the inhabitants of Tamaulipas in the 16th and 17th centuries. The first permanent Spanish settlement in the area was Tampico in 1554, further settlement was done by Franciscan missionaries, widespread cattle and sheep ranching by the Spanish bolstered the area’s economy while forcing native populations from their original lands. Repeated indigenous rebellions kept the area unstable and weakened colonial interest in the region, what is now Tamaulipas was first incorporated as a separate province of New Spain in 1746 with the name Nuevo Santander. The local government capital during this time moved from Santander to San Carlos, the territory of this time spanned from the San Antonio river to the north east to the Gulf of Mexico, then south to the Panuco River near Tampico and west to the Sierra Madre Mountains. The area became a haven for rebellious Indians who fled there after increased Spanish settlements in Nuevo León, one of these groups was known as Lipan. By 1790 Europeans turned their attention from the groups and focused on containing the Apache invaders. In northeastern Coahuila and adjacent Texas, Spanish and Apache displacements created an ethnic mix. Here the local Indians mixed with displaced groups from Coahuila and Chihuahua, some groups, to escape the pressure, combined and migrated north into the Central Texas highlands. In 1824, after the Mexican War of Independence from Spain, during the fights between centralists and federalists that soon followed, the successful Texas Revolution led to the creation of the Republic of Texas in 1836

Since the 1980s has been an important political party winning local, state, in 2000, PAN candidate Vicente Fox was elected for a six-year Presidential term, in 2006, PAN candidate Felipe Calderón succeeded Fox in presidency. During the period 2000-2012, both houses of the legislature had PAN pluralities, but the party did not have a majority in either house of the Congress. In the 2006 legislative elections the party won 207 out of 500 seats in the Chamber of Deputies and 52 out of 128 Senators, in the 2012 Legislative Elections, the PAN won 38 seats in the Senate, and 114 seats in the Chamber of Deputies. The National Action Party was founded in 1939 by Manuel Gómez Morín and he saw the need for the creation a permanent political party rather than an ephemeral organization to oppose the expansion of power by the post-revolutionary Mexican state. When Gómez Morín was rector of in 1933-35, the government attempted to impose socialist education, in defending academic freedom, Gómez Morín forged connections with individuals and groups that later came together in the foundation of the PAN in September 1939. Gómez Morín was not himself a militant Catholic, but he was a believer who rejected liberalism and individualism. In 1939, Gómez Morín and a significant number of UNECs leadership came together to found the PAN, the PAN’s “Doctrine of National Action” was strongly influenced by Catholic social doctrine articulated in Rerum novarum and Quadragesimo anno and rejected Marxist models of class warfare. The PAN’s newspaper, La Nación was founded by another former UNEC member, the relationship between the PAN and the Catholic Church was not without tension. The partys founder Gómez Morín was leery of clerical oversight of the party, although its members were mainly urban Catholic professionals, for its part, the Church hierarchy did not want to identify itself with a particular political party, since the Constitution of 1917 forbade it. In the 1950, the PAN, which had seen to be Catholic in its makeup. The PAN initially was a party of “civic example”, an independent loyal opposition that generally did not win elections at any level, however, in the 1980s it began a transformation to a political power, beginning at the local and state levels in the North of Mexico. A split in the PAN occurred in 1977, with the faction and the more secular wing splitting. The conflict came to a head and in 1977. The party ran no candidate in 1976.

Party of the Democratic Revolution
–
The Party of the Democratic Revolution is a social democratic political party in Mexico. The PRD is one of the three political parties in Mexico, the others being the Institutional Revolutionary Party and the National Action Party. The PRD originated from the Democratic Current, a political faction formed in 1986 from the PRI Party, the PRD was formed after the 1988 electoral fraud which sparked a movement away from the authoritarian rule of the PRI. Today, the PRD is a member of the Broad Progressive Front alliance, the PRD has its origins with the leftists members of the PRI, Institutional Revolutionary Party. The PRI had dominated Mexican politics since its founding in 1929, in 1986, three PRI members – Rodolfo González Guevara, Porfirio Muñoz Ledo, and Cuauhtémoc Cárdenas – formed the Democratic Current, a political faction within the PRI. The Democratic Current was also against technocratization, in which the people in power had not held public office and were scholars that were educated abroad. Under the Miguel de la Madrid presidency which lasted from 1982-1988, the Democratic Current did not have many technocrats and was thus left out of the decision making process. This political marginalization led the Democratic Current members to be vocal about their concerns because they did not have a position of power to protect within the PRI. However, the PRI refused to acknowledge the Democratic Current as an organization unless they joined a union, the forming of a group that was not united because of work but because of difference in ideology within the PRI caused fear of division within the party. Once de la Madrids six-year term as president was coming to a close, the PRI had no process to apply as candidate so Cardenas could not run as a candidate for president. On October 4,1987 Carlos Salinas de Gortari was ultimately chosen as the PRI candidate, Gortari did not embody anything that the Democratic Current wanted and many of the Democratic Current members left the PRI including Cárdenas during November 1987. Some Democratic Current members went on to support Cárdenas in his 1988 quest for presidency, on October 12,1988 Cárdenas became the Authentic Party of the Mexican presidential candidate. Cárdenas still remained an independent candidate due to laws which meant that many parties could choose Cárdenas as their candidate. The win of the PRIs candidate, Carlos Salinas de Gortari, years later, it was determined that there was indeed electoral fraud in the election. The 1988 electoral fraud sparked a movement against the rule of the PRI. As an integral part of the movement towards democracy, the Party of the Democratic Revolution was formed as Mexico’s only leftwing party, on May 5,1989, Cárdenas declared the establishment of the PRD. Former PRI members who helped found the PRD include, Cárdenas, Andrés Manuel López Obrador, Porfirio Muñoz Ledo. The party was founded by smaller left-wing parties such as the Mexican Communist Party, Unified Socialist Party of Mexico, Socialist Mexican Party, the PMS donated its registration with the Federal Electoral Commission to enable the new party to be established
