The history of Santa Maria, a city in the very heart of the Brazilian state of Rio Grande do Sul, is closely tied to its strategic geographical location. The city, which is today an important educational and commercial centre, has evolved from a military camp into one of the region's key municipalities.
The city's history begins in the late 18th century. The settlement was founded on May 17, 1797, as a camp for Portuguese and Spanish demarcation troops who were defining the borders of colonial possessions. Thanks to its location in the Jacuí River valley, this site became a convenient point for stopping and resupplying. The settlement's original name was Santa Maria da Bôca do Monte, which translates as "Saint Mary at the Mouth of the Mountain." Santa Maria received city status in 1858.
The growth and development of Santa Maria were largely determined by its geography. The city became a vital transport hub, especially following the construction of railway lines that connected it to other parts of the state and the country. This facilitated Santa Maria's transformation into a major trading centre for an agricultural region specializing in cattle breeding and grain cultivation. The status of an important transport and commercial hub has remained with the city for many years.
The economy of early Santa Maria was focused around agriculture and servicing transport flows. Railway workshops appeared in the city, as well as enterprises for processing local produce, such as breweries, tanneries, and meat processing plants. Like many other cities in southern Brazil, Santa Maria experienced the influence of European immigrants, which was reflected in its culture and architecture. Over time, the city also gained a reputation as an educational centre, which contributed to further population growth and cultural diversity.
