The history of Porto Alegre, capital of Rio Grande do Sul, Brazil, officially begins on March 26, 1772,[1] when the primitive village was elevated to the condition of a parish. However, its origins are older, since the settlement was created as a result of the colonization of the area by Portuguese ranchers in the 17th century. The region, in fact, has been inhabited by man since 11,000 years ago. Throughout the 19th century, the settlement began to grow with the help of many European immigrants of various origins, African slaves, and portions of Hispanics from the River Plate region. At the beginning of the 20th century, Porto Alegre's expansion acquired a very accelerated rhythm, consolidating its supremacy among all the cities in Rio Grande do Sul and projecting it on the national scene. From then on, its most characteristic traits, only sketched out in the previous century, were defined; many still remain visible today, especially in its historic center. Throughout the entire 20th century, the city strove to expand its urban network in an organized way and provide it with the necessary services, achieving significant success, but also facing various difficulties, at the same time as it developed its own expressive culture, which, at some moments, influenced other regions of Brazil in many fields, from politics to the plastic arts.[2][3] Today, Porto Alegre is one of Brazil's largest capitals and one of the richest and one with the best quality of life,[4] having received several international distinctions.[1] It hosts many important events and has been pointed out several times as a model of administration for other large cities.[5]
