The history of São Carlos, located in the heart of the state of São Paulo, is closely intertwined with Brazil's economic development in the 19th century. The official founding date of the city is November 4, 1857. Initially, it was a small settlement on the route to the gold mines in Cuiabá and Goiás, which was established at the end of the 18th century. Thanks to its strategic location and fertile soils, the settlement began to grow rapidly.
A key factor in the establishment of São Carlos was the coffee boom that swept the region. The fertile soils were ideal for coffee cultivation, which attracted significant investment to the city and contributed to its transformation into one of the major centers of the "coffee economy." A decisive role in its development was played by the construction of railways that connected the plantations with the Port of Santos, ensuring product exports and facilitating the influx of European immigrants, mainly from Italy, who arrived to work on the coffee fazendas. By 1865, São Carlos had received village status, and in 1880, it became a city, reflecting its rapid growth and increasing importance.
The city's early economy was almost entirely dependent on the coffee harvest, and its society was shaped by the influence of the "coffee barons" and the blending of the local population with immigrants. This process laid the foundation for the multicultural character that São Carlos maintains today. Economic prosperity allowed for the construction of the first schools, churches, and public buildings, which formed the historical appearance of the city center and established the groundwork for its future development as an important educational and technological hub.
