Mossoró
Mossoró is a Brazilian municipality in the interior of the state of Rio Grande do Norte, recognized as the capital of the Brazilian semi-arid region. Covering an area of approximately, it is the largest municipality in the state by area, located 281 kilometers from the state capital, Natal. With a population of 264,577 inhabitants according to the 2022 demographic census, it ranks as the second most populous city in Rio Grande do Norte, after the capital, the most populous in the state's interior, and the 108th in Brazil.
Situated between two state capitals, Natal and Fortaleza, both connected by the BR-304 highway that bypasses the municipality, Mossoró is one of the main cities in the Northeast's interior and is experiencing significant economic and infrastructural growth. It is one of the most attractive cities in Brazil for investments. The municipality is one of Brazil's largest producers of onshore oil, and its economy is notably driven by irrigated horticulture, largely oriented toward export.
Emancipated from Assu in 1852, the municipality's history is marked by significant events, including the abolition of slavery in 1883, five years before the Lei Áurea, the first female vote in Brazil, and the historic resistance against the bandit group led by Lampião in 1927. A cultural hub of Rio Grande do Norte, Mossoró is also prominent in business tourism. Annual festivities attract numerous tourists, such as the Mossoró Cidade Junina, one of Brazil's largest June festivals, and the Auto da Liberdade, the country's largest open-air theatrical performance.
Etymology
The origin of the name "Mossoró" remains uncertain, though several theories exist. One suggests it derives from "Monxoró," the name attributed to the indigenous people who first inhabited the region. Another theory posits that it comes from "Mororó," a resilient and flexible tree.According to current Portuguese orthography rules, the correct spelling is Moçoró, as the letter "ç" is used for words of Tupi origin. The name, which comes from Tupi, means erosion, cut, or rupture. Over time, the spelling evolved from mo-so-'roka to mossoró and finally to moçoró. The term moçoroense, referring to the municipality's residents, derives from the same root.
History
Origins
Around 1600, references to salt pans in the region suggest the initial settlement of what is now Mossoró. According to Luís da Câmara Cascudo, a historian from Rio Grande do Norte, Dutchmen Gedeon Morris de Jonge and Elbert Smiente extracted salt from the area until around 1644.In 1701, Fernando Martins Mascarenhas, governor of Pernambuco, granted lands in Paneminha to the Carmo Convent in Recife, including sesmarias that remain part of Mossoró today. Additional lands were gradually allocated to Brazilians and Portuguese. During the 18th century, farms were established along a river by landowners from other regions. The population was primarily composed of cowboys, breeders, and farm managers, as landowners typically resided elsewhere, such as in Natal or neighboring provinces such as Paraíba and Ceará. The first permanent settlers are believed to have been the Gamboa, Guilherme, and Ausentes families, who lived along the Mossoró River and gradually spread to areas as far as Apodi.
In the mid-18th century, around 1760, Portuguese sergeant-major Antônio de Souza Machado and his family relocated to the area, aiming to populate it. He owned the Santa Luzia farm and ordered the construction of the Santa Luzia chapel, a foundational milestone for Mossoró, officially established on August 5, 1772.
19th Century
On October 27, 1842, by provincial resolution no. 87, the district of Mossoró was created as part of the municipality of Assu, and the parish of Santa Luzia was separated from Apodi, with the chapel elevated to the status of parish church. Until the appointment of its first vicar, Priest Antônio Joaquim Rodrigues, in 1844, the new parish was led on an interim basis by Father José Antônio Lopes da Silveira. On March 15, 1852, provincial law no. 246 separated the district and elevated Mossoró to the category of a village, making it a new municipality of Rio Grande do Norte. On March 23 of the same year, the district of São Sebastião was created, today the municipality of Governador Dix-Sept Rosado. Still that year, the first elections for the Municipal Council were held, which was formally inaugurated on January 24, 1853, presided over by Father Antônio Freire de Carvalho. In 1855, Priest Antônio Joaquim, parish vicar of Mossoró, created the Brotherhood of Santa Luzia, and starting in 1858, the chapel was demolished and rebuilt over the next ten years.By provincial law no. 499 of May 23, 1861, the District Court of Mossoró was created, separated from the Court of Assu. Finally, on November 9, 1870, provincial law no. 620 elevated the village of Mossoró to the status of a city. In 1872, the first demographic census of Brazil was conducted, and Mossoró ranked fourteenth among the 22 municipalities of the province, with exactly 8,000 inhabitants, of whom 293 were enslaved people. On October 17 of that same year, the journalist Jeremias da Rocha Nogueira founded the newspaper O Mossoroense, and on December 5, the district of Areia Branca was created, but it was extinguished on December 19, 1876. On August 18, 1873, the Municipal Council authorized the construction of the city’s first cemetery, now known as São Sebastião Cemetery. In that same year, the Masonic lodge of Mossoró was founded.
On August 30, 1875, at the headquarters of O Mossoroense, around three hundred women, led by Anna Floriano, took to the streets in protest against the mandatory military draft. They held the district clerk hostage and publicly tore up the recruitment book and papers that forced Mossoró’s men to join the armed forces to fight in the Paraguayan War. Between 1877 and 1879, the Northeast suffered a severe drought that caused a mass exodus from the city to coastal areas—including most of the enslaved population—and in 1878, the city’s public jail was built.
In 1882, an abolitionist movement began with the goal of ending slavery in Mossoró, resulting in the founding of the Mossoroense Liberation Society on January 6, 1883. That year, only 86 enslaved people remained, forty of whom were freed by manumission in June, at the Masonic lodge. Effective abolition took place on September 30, 1883, and the city began to receive many fugitive enslaved people from other towns.
On June 1, 1886, the district of São Sebastião was extinguished and then reinstated on April 2, 1887, the same year the first postal and telegraph agency was created. After the fall of the monarchy and the Proclamation of the Republic on November 15, 1889, the government of Rio Grande do Norte issued a decree dissolving the Mossoró City Council and creating a municipal intendency, which took effect on January 18, 1890. On November 22 of the same year, the district of Areia Branca was reinstated by decree, becoming a municipality on February 16, 1892.
1900 to 1926
After the creation of Mossoró’s first secondary school on September 7, 1900, the bishop of the Diocese of Paraíba, Adauto Aurélio de Miranda Henriques, founded the Santa Luzia Gymnasium on March 2, 1901, appointing Canon Estevam Dantas, the parish vicar, as its first director. The school was closed by the diocese in 1908 and reopened only in 1912, when Rio Grande do Norte came under the newly created Diocese of Natal.On September 30, 1904, during the celebration of 21 years since abolition in Mossoró, the Monument of Liberty was inaugurated in what is today Redemption Square. On November 15, 1908, the state government created the September 30 School Group, opened on May 12 of the following year. Earlier, on December 12, 1908, Mossoró gained its first movie theater, the Almeida Castro Cinema, which operated inside the Grande Hotel.
In 1912, another cinema — Politeama — arrived in the city, one year after opening in Natal, and the Franciscan sisters founded the Sacred Heart of Mary School on August 2. On September 13, 1913, nearly thirty years after abolition, the Mossoró intendency declared September 30 a municipal holiday. In 1914, the new public slaughterhouse was inaugurated and the city’s first urban plan was drafted by engineer Henrique de Novaes. In 1915, during yet another great drought, the Mossoró–Porto Franco Railway began operating, and on December 19, 1916, the Mossoró Electric Power and Improvements Company was founded, bringing electric lighting to the entire city, which replaced kerosene lamps. After its cornerstone was laid in October 1915, the Church of São Vicente was inaugurated in July 1919.
On January 19, 1922, by state decree, the Mossoró Primary Normal School was created, inaugurated a month and a half later, on March 2. On September 7 of the same year, during the celebration of Brazil’s first centennial of independence, the Market Square was renamed Independence Square, and an obelisk was placed at its center. On July 23, 1926, the diocesan bishop of Natal, Dom José Pereira Alves, created the Parish of the Sacred Heart of Jesus, officially installed on August 1. The chapel, later elevated to parish church, had been built between 1904 and 1907.
Resistance to Lampião's gang and the first female vote
Another significant act of resistance in Mossoró occurred in 1927, when the city stood against the gang of the Northeast's most infamous cangaceiro, Virgulino Ferreira da Silva, popularly known as "Lampião." That year, Mossoró was experiencing notable economic growth in commerce and industry. The gang entered Rio Grande do Norte through the municipality of Luís Gomes between June 9 and 10, passing through several cities in western Rio Grande do Norte before reaching Mossoró, where Lampião suffered his only defeat since becoming a cangaceiro.On June 12, the cangaceiro and his companions arrived in the district of São Sebastião, now the municipality of Governador Dix-Sept Rosado, then a district of Mossoró. From there, he sent a telegram warning the population of an impending attack, causing widespread panic. Mayor Rodolfo Fernandes organized an exodus, setting up trenches to repel the invaders.
On June 13, Lampião and his gang reached Sítio Saco, where he sent a note demanding 400 réis in money to spare the city, a demand rejected by the mayor. The attack on Mossoró began at 4 p.m., with the gang leader dividing his cangaceiros into three groups, each targeting a different location: the first attacked the mayor's house; the second invaded and attacked the Mossoró railway station; and the third targeted what is now the São Sebastião Cemetery. An hour later, the gang retreated, leaving behind Colchete and Jararaca, who was wounded, captured, and killed days later. Jararaca was buried in the same cemetery attacked by the gang and later became a figure of local reverence among the people of Mossoró.
The following year, Mossoró made history again as the site of Brazil's first female vote, a globally significant event, as most countries still prohibited women from voting. At the time, the Brazilian Constitution, enacted in 1891, granted voting rights only to the wealthy. Women, slaves, the illiterate, and the poor were excluded. In 1928, Celina Guimarães Viana, a teacher and football referee, obtained the first female voter's card and cast the first female vote in Brazil. This inspired women in Rio Grande do Norte and nine other Brazilian states to organize street protests demanding voting rights, which had already been secured in Rio Grande do Norte. Women nationwide gained the right to vote six years later, in 1934, under President Getúlio Vargas.
From 1929 to the 1970s
On January 1, 1929, Rafael Fernandes Gurjão took office as Mossoró’s first constitutional mayor, elected on September 2 the previous year. He held office for only three months, until April 2, when his vice-mayor, Vicente Carlos Saboia Filho, took over. He was deposed on October 8, 1930, when all mayors in the state were removed by decree.On July 28, 1934, by the papal bull Pro Eclesiarum Omnium issued by Pope Pius XI the Diocese of Mossoró was created, separated from the Diocese of Natal and subordinate to the Archdiocese of Paraíba. However, the news only reached Mossoró on September 14, when the parish vicar of Saint Lucy, Priest Luiz Ferreira da Cunha Mota, received a telegram from the bishop of Natal, Dom Marcolino Esmeraldo de Souza Dantas, who had been appointed apostolic administrator of the new diocese. The diocese was officially installed on November 18, 1934.
On January 23, 1943, Mossoró inaugurated Cine Pax, located across from Rodolfo Fernandes Square, operating on the upper floor of the home of its owner, businessman Jorge Pinto. The cinema opened with the screening of Belle Starr. Another cinema, Cine Déa, opened in 1944. By the 1960s, at least seven cinemas had opened in the city, including Cine Cid, across from the Vicar Antonio Joaquim Square, inaugurated on July 22, 1964, with the film Rome Adventure.
In 1948, Mossoró held direct elections for mayor again, with the candidate Jerônimo Dix-Sept Rosado Maia winning. He remained in office until 1950, when he was elected governor of Rio Grande do Norte, taking office in 1951. He governed the state until July 12, 1951, when, as a result of an air disaster, he died in Aracaju, the capital of Sergipe. In his honor, on the 25th of that month, a municipal law changed the name of the district of Sebastianópolis, formerly the village of São Sebastião, to Governador Dix-Sept Rosado, which became a municipality on April 4, 1963, through state law 2878.
On March 29, 1964, the diocesan bishop Dom Gentil Diniz Barreto dissolved the Parish of the Sacred Heart of Jesus and elevated the São Manoel Church to parish status. The Sacred Heart Church became a sanctuary of perpetual adoration and was incorporated into the Santa Luzia parish. On April 18, 1967, Mayor Raimundo Soares de Souza created the Mossoró Higher School of Agriculture, which was inaugurated eight months later, on December 22. Its first admissions exam was held the following year, and its first agronomy class graduated in 1971.
In 1970, when the municipality had a population of 97,245 inhabitants, Mossoró’s industrial district was established, and in 1975 the Abolição neighborhood emerged, along with the city’s first master plan, which defined its first urban boundary. Three years later, the first oil well was discovered in Mossoró, at the site of the current Thermas Hotel. In 1980, the city expanded further with the creation of new neighborhoods, and the population reached 145,981.
1980s to the present
On December 15, 1981, the district of Baraúna was separated and became a new municipality. During that decade, Mossoró became a hub of irrigated fruit production, particularly melons. Urban expansion and population growth continued, though at a slower pace than in previous decades. Meanwhile, railway transport declined, leading to the deactivation of the Mossoró–Sousa Railway and, in 1995, the dissolution of the Mossoró Railway Company.In 1984, the Diocese of Mossoró celebrated its fiftieth anniversary, and Pope John Paul II proclaimed Saint Lucy the patron saint of the diocese. In 1985, the city was hit by heavy rains, and the Mossoró River recorded the largest flood in its history, inundating downtown and riverside neighborhoods. In 1986, more petroleum was discovered in the municipality, this time in the Canto do Amaro area along BR-110, making Mossoró the largest onshore petroleum producer in Brazil. In the 1988 elections, the city elected its first female mayor, Rosalba Ciarlini, who served until 1992. In 1990, five new neighborhoods were created, and the 1991 census recorded a population of 192,267 — growth that continued slowing compared to 1960–1980 rates.
Rosalba was succeeded by Dix-Huit Rosado, who had previously served two mayoral terms. On December 29, 1994, Mossoró inaugurated the Mossoró Decentralized Teaching Unit, which became the Federal Center for Technological Education in 1999 and, in 2008, the Federal Institute of Rio Grande do Norte. On October 22, 1996, Mayor Dix-Huit Rosado died in office and was succeeded by Sandra Rosado. In that year’s election, Rosalba was once again elected mayor. On September 24, 1999, the old Mossoró railway station was reopened as the Estação das Artes Elizeu Ventania, named after a local poet and repentista.
In the 2000 elections, Rosalba was elected for her third term. In 2004, the Dix-Huit Rosado Maia Municipal Theater was inaugurated at Cícero Dias Square. On July 29, 2005, 38 years after the founding of ESAM, it was transformed into the Federal Rural University of the Semi-arid Region by federal law no. 11,155. In 2008, the Mossoró Resistance Memorial was inaugurated. In the 2012 elections, Cláudia Regina won, took office in 2013, but had her mandate definitively revoked in December that same year, being succeeded by the president of the Municipal Council, Silveira Júnior. In 2016, Rosalba Ciarlini was elected mayor for the fourth time. In 2017, Mossoró received the title of Capital of the Semi-Arid by federal law, and in 2018, a municipal law designated Vigário Antônio Joaquim Square as the city’s official ground zero. In the 2020 elections, Allyson Bezerra was elected mayor, and he was re-elected in 2024 with the largest number of votes in the city’s history.
Geography
According to the regional division established by the Brazilian Institute of Geography and Statistics in 2017, the municipality of Mossoró is part of both the intermediate and immediate geographic regions of Mossoró. Prior to this, under the previous division into microregions and mesoregions, Mossoró was part of the Mossoró microregion, which was included in the Oeste Potiguar mesoregion. The municipality is located 281 kilometers from Natal, the state capital, 237 kilometers from Fortaleza, Ceará, and 1,977 kilometers from Brasília, the federal capital. Covering an area of 2,099.36 km²,, Mossoró is the largest municipality in Rio Grande do Norte by territorial extent. It borders the municipalities of Aracati, Tibau, and Grossos to the north; Governador Dix-Sept Rosado and Upanema to the south; Areia Branca, Serra do Mel, and Assu to the east; and Baraúna to the west.The terrain of the municipality, with predominant altitudes below 100 meters, comprises the Chapada do Apodi, the Sertaneja-São Francisco Depression, the sublittoral depression, and fluvial plains. The highest point in the municipality is Serra Mossoró, located 16 kilometers from the city, with a peak at an altitude of 268 meters.
The entire territory of the municipality lies within the Apodi/Mossoró River Hydrographic Basin. The main rivers flowing through the municipality are the Apodi/Mossoró and Carmo rivers. The main streams include Bonsucesso, Cabelo Negro, São Raimundo, and Pai Antônio. The largest reservoirs, with capacities equal to or greater than 100,000 cubic meters of water, are the Açude Favela, Lagoa de Paus Dam, Baixo Dam, Mossoró Dam, and Santana dos Pintos Dam.
The biodiversity of Mossoró is evident in both its flora and fauna, with the latter being particularly notable due to the discovery of the species Hypsolebias bonita, an annual fish locally known as the "cloud fish." This species was named in honor of Maria Bonita.
The predominant soil types in the municipality are eutrophic Cambisol, which has high fertility, clay texture, and good to moderate drainage; rendzina, similar to Cambisol but with moderate to imperfect drainage; and Latosol, specifically the red-yellow eutrophic type, with medium to high fertility, medium texture, and good to excellent drainage. Other soil types include eutrophic equivalent red-yellow podzolic soils, solonchak, and Vertisol.
These soils are covered by hyperxerophilous caatinga, a vegetation type consisting of low-growing species adapted to drought, such as the faveleiro, black jurema, and mofumbo, as well as halophytic vegetation with species adapted to high salinity levels, and carnaúba groves, where the carnaubeira and palm are predominant species. Part of Mossoró’s territory lies within the Furna Feia National Park, an environmental preservation area spanning 8,494 hectares. The park was established by presidential decree on 5 June 2012, during World Environment Day celebrations, to preserve the local caatinga biome.
Mossoró, with its semi-arid climate classified as Bsh, is one of the hottest municipalities in Rio Grande do Norte. Temperatures can reach 38 °C on some occasions, with the apparent temperature occasionally exceeding 40 °C.
