The city of Mossoró, located in the state of Rio Grande do Norte, boasts a rich history closely tied to the development of the arid lands in northeastern Brazil. Its formation is a prime example of how harsh natural conditions and economic opportunities shape the unique character of a settlement.
The history of Mossoró begins with a small settlement that emerged around the Santa Luzia farm in the 18th century. This region, known as the sertão (hinterlands), attracted cattle herders seeking new pastures. Mossoró officially received city status on 15 March 1852, marking the starting point for its administrative and economic growth. Initially, development was slow, but its advantageous geographical position between the coast and the interior of the state created the prerequisites for future prosperity.
The early development of Mossoró was defined by several key factors. The main driver of the city's economy became the salt industry. Thanks to its proximity to salt flats and access to the Atlantic Ocean, Mossoró transformed into the country's largest producer of sea salt, which facilitated the development of transport infrastructure. Alongside this, traditional regional activities played an important role: cattle ranching and agriculture. The city also quickly became a vital trade hub connecting rural areas with port cities. An integral part of its cultural identity became its famous spirit of resistance. The most striking example is the successful defence of the city against the gang of the bandit Lampião in 1927, an event that locals take great pride in and which is immortalised in the name of the city museum.
