San Luis Potosí, often called San Luis or SLP, is a major city in Mexico. It is the capital and largest city of the Mexican state of San Luis Potosí. The city is located high up, about 1,864 meters (6,115 feet) above sea level.
In 2015, the city had about 824,229 people. Its larger metropolitan area, which includes nearby towns like Soledad de Graciano Sánchez, has about 1,221,526 people. This makes it the eleventh largest metropolitan area in Mexico.
The city is in the west-central part of the state. It is named after Louis IX of France, who is the city's patron saint. The name Potosí was added because of the very rich silver and gold mines found nearby. These mines were the main reason the city was founded in 1592.
Today, San Luis Potosí is an important industrial center in central Mexico. Many foreign companies have invested here. This is because the city is located perfectly between Mexico City and the United States border. It is also in the middle of the "triangle" formed by Mexico's three biggest cities: Mexico City, Guadalajara, and Monterrey.
Besides its strong industry, San Luis Potosí is also becoming a popular place for tourists. Its historic center has amazing buildings with different art styles. In 2010, this historic center became a UNESCO World Heritage Site. It is part of the old trade route called Camino Real de Tierra Adentro.

A Look at San Luis Potosí's Past
Early History: Before the Spanish Arrived
Before the Spanish came, the area of San Luis Potosí was home to two main cultural groups. The southern and eastern parts of the state had Otomi and Huastec kingdoms. But the northern and central-west areas, where San Luis Potosí city is now, were lived in by the Chichimeca.
The Chichimeca were nomadic groups. This means they moved around a lot and did not build big cities like other ancient civilizations. They were known as fierce warriors who often fought among themselves.
When Spanish explorers arrived in Mexico, it took them about 100 years to settle in these northern lands. The first Spanish settlers in the late 1500s faced constant attacks from the Guachichil tribes, a group of Chichimeca. These tribes attacked traders traveling to Zacatecas. The Spanish called this area "El Gran Tunal," meaning "Grand Place of Tuna Fruit." Finally, in 1589, peace was made between the Chichimeca and the Spanish. This ended the Chichimeca War.
Colonial Times: The City's Founding
A Franciscan religious mission was set up in the area in 1583. This was nine years before the city was officially founded. In early 1592, rich mines were found in a place called Cerro de San Pedro. However, there wasn't enough water there to properly get the minerals out.
A short distance away, there was a valley with plenty of water. This led to the creation of a new town to help with the mining work. The city of San Luis Potosí was officially founded on November 3, 1592. It was started by Miguel Caldera and Juan de Oñate.
Mexico's Independence and Revolution
For a short time in 1863, San Luis Potosí became the capital of Mexico. This happened during the French invasion, when President Benito Juárez led the government from here.
The Plan of San Luis Potosí was a very important document. It was issued on November 20, 1910, and it started the Mexican Revolution. This revolution was against the leader Porfirio Díaz. He had arrested his opponent, Francisco I. Madero, during the 1910 election. Madero escaped and then called on Mexicans to fight the government.
San Luis Potosí Today
Today, the city's downtown area is full of beautiful plazas and old colonial buildings. The "Plaza de Armas" is home to a grand cathedral and the governor's palace, which was built in 1770. The nearby "Templo de Nuestra Señora del Carmen" is famous for its colorful domes and altars. It is considered one of Mexico's most beautiful churches. San Luis Potosí also has a bullring called Plaza de Toros Fermin Rivera.
Outside the historic center, a modern industrial city has grown. The Universidad Autónoma de San Luis Potosí (UASLP) is a well-known university in the city. It started as a Jesuit College in 1624 and became a university in 1923. It is now one of the best universities in Latin America.
With about one million people, San Luis Potosí is now the twelfth largest metropolitan area in Mexico. It is a major center for business and industry. Its location in the middle of the "triangle" of Mexico's three largest cities makes it very important for the economy.
In recent years, many European and American companies have invested in San Luis Potosí. The city's stable political and economic situation has encouraged large international companies to set up businesses here. A survey by The Investor magazine even named San Luis Potosí and its surrounding area the third-best place to live in Mexico.

Festivals and Celebrations

The Procession of Silence is a special event held every year. It remembers the story of Christ's suffering and death. It takes place on the night of Good Friday. The procession starts at the Templo del Carmen and moves through the historic streets of San Luis Potosí. Drums and bugles play music, but the people in the procession and those watching do not speak. This is why it is called the "Procession of Silence." It is one of the most important Easter celebrations in Mexico. In 2013, it was recognized as part of the cultural heritage of the state of San Luis Potosí.
