The Baixa de Cassanje revolt: cotton, “Maria” and the bombs of 1961

The rains had come to the Baixa de Cassanje, and January was planting time. On 4 January 1961, in the village of the soba (chief) Quivota, about ten kilometres from the Portuguese administrative post of Milando, villagers took hold of two foremen of the cotton company Cotonang and tied them up.2 sources2 sources

They shouted against the whites. According to the colonial records summarised by the historian Aida Freudenthal, they said they would attack anyone who made them grow cotton or work for the state, that they would no longer obey the chefe de posto, the local administrator, and that they would pay no more tax.1 source1 source

Across the plain, growers burned the cotton seed the company had handed out and piled their hoes by the roadside. A note found in a Cotonang foreman's pocket explained the new order in the language of prophecy.3 sources3 sources

Within six weeks the strike had become an uprising across the Baixa, and the Portuguese state had answered it with infantry companies, bombers and the political police. The growers who died in the repression were never counted. Estimates written since range from about 200 to 20,000.3 sources3 sources

In 1961 Angola was a Portuguese colony, officially an “overseas province”, ruled from Lisbon by António de Oliveira Salazar's Estado Novo dictatorship. Most Black Angolans were classed as indígenas, natives, under a statute that kept them outside Portuguese citizenship until it was repealed on 6 September 1961.1 source1 source

The Baixa de Cassanje (also spelt Cassange or Kassanje) is a wide plain along the Cuango river in what was then Malanje district, on the border with the former Belgian Congo. Its people had resisted Portuguese conquest until 1911. By 1961 it was Angola's main cotton-growing region.2 sources2 sources

The company that ran the cotton zone was the Companhia Geral dos Algodões de Angola, known as Cotonang. Cann describes it as a Luso-Belgian company founded in 1926; Silva calls it Belgian. Its concession east and west of Malanje covered some 80,000 square kilometres. A second, more recent firm, Lagos & Irmão, held another.2 sources2 sources

The system worked like this. Families were moved to plots the company designated, about a hectare each by René Pélissier's reckoning, and told to grow cotton there instead of cassava, maize, beans and groundnuts. They received seed and advice but no wages and no food. At the end of the season they had to sell the whole crop to the concessionaire at a fixed price, far below the world market.3 sources3 sources

The risk fell on the growers. A Portuguese witness quoted by Anabela Silveira wrote that if a flood ruined a field, the company paid nothing for the lost year, and that when the soil was worn out the foremen moved families to plots fifteen or twenty kilometres from their huts. Grading cheated them too: first-class cotton was often bought as second class.1 source1 source

Even some of the officers sent to restore order said so. Major Rebocho Vaz, who later led the operation, reported that the people of the Baixa lived in “absolute moral and material misery”. The commander of the 3rd Company of Special Caçadores, light infantry, wrote that villagers at Lundo showed him fresh scars from the whip and the hippo-hide cavalo-marinho.1 source1 source

What turned grievance into revolt was a movement its followers called simply Maria. Its best-known figure was António Mariano, a man from the region who had left Malanje in 1959 for the Congo. According to Cann, he worked there as a chauffeur, met members of the UPA, the Union of the Peoples of Angola, in Léopoldville and came back in December 1960.2 sources2 sources

The movement mixed nationalism with religion. PIDE, the political police, reported catechists arriving at the end of 1960 with the “Good News of Maria”, the protecting goddess of Black people, who had come to free the people of Angola from the white man's yoke. Initiates were baptised with “Maria water” and told to keep fifteen commandments, the first of which was not to work for whites. Many believed Portuguese bullets would turn to water.3 sources3 sources

Several of the names came from across the border. The Congo had become independent in June 1960, and the rebels invoked the authority of President Joseph Kasavubu, Patrice Lumumba and Maria. Agents of the Congolese African Solidarity Party, the PSA, known locally as pessis, crossed the Cuango; the Maholo people of the Baixa had kin on both banks.3 sources3 sources

Who organised it is still argued over. Rosário Neto, a UPA leader, wrote in 1966 that Mariano led the revolt, and that the strike planned in Léopoldville had been set for 15 March 1961 but the cotton season began in January. Silveira leans towards UPA involvement; Cann, relying on a company commander's recollections, blames PSA agents and notes that no nationalist movement claimed it at the time.2 sources2 sources

Valentim Alexandre, in his 2021 history of the Angolan revolts, rejects single explanations. As Pedro Aires Oliveira summarises the book, the cotton system gave the peasants strong reasons to rebel, the Maria cult belonged to a wider current of messianic protest, and Congo's independence galvanised the north, but Alexandre does not accept colonial officials' claims that the revolt was stirred up or orchestrated from outside.1 source1 source

In January the strike spread village by village. Growers refused to work the cotton or pay the personal tax, and destroyed their cadernetas, the passbooks every indígena had to carry. On the night of 11 January a Cotonang foreman was shot dead with a muzzle-loader at Ganga Moxica, for reasons the records do not give; Freudenthal suggests a link with the strike and the company agents' violence. “We do not want to kill; but if the white man comes to kill us, we kill too,” a soba told the administration.2 sources2 sources

A letter written in Luanda in February 1961 and seized by PIDE, cited by Freudenthal, spoke of 85 striking peasants massacred in mid-January. Missionaries reported that Cotonang foremen had beaten strikers with clubs.1 source1 source

The colonial authorities hesitated. Angola was under scrutiny at the United Nations, and a Cotonang administrator later complained that the Governor-General “did not want a single shot fired” for fear of the international repercussions. Patrols of the 3rd Company of Special Caçadores tried to talk villagers back to work. By late January the revolt had reached Tembo Aluma, Cunda-Ria-Baza, Quela, Marimba and Xá-Muteba, and some villagers were fleeing across the border.2 sources2 sources

The rebels cut the roads with felled trees, destroyed bridges and burned the barges at river crossings. They broke into shops and missions and harassed the few white traders and Cotonang agents. On 30 January white women and children were evacuated, and on 3 February rebels set fire to a company warehouse at the Quiria market.2 sources2 sources

On 3 February the governor of Malanje met the commander-in-chief, the Air Force commander and the PIDE delegate. The PIDE record of the meeting shows them weighing the cost abroad of using force. The next day an attack on the 4th Company of Special Caçadores killed two soldiers, and the hesitation ended.1 source1 source

Major Camilo Rebocho Vaz took command of a battalion made up of the 3rd, 4th and 5th companies. On 6 February, at Teca-Ria-Quinda beyond Quela, the 4th Company met a crowd of several thousand armed mostly with catanas, bush knives, and canhangulos, home-made muzzle-loaders. The figures of the officer-historian António Lopes Pires Nunes, cited by Cann, are 71 dead and 41 wounded among the villagers, and one soldier killed and four wounded.1 source1 source

Freudenthal's reading of the military reports for the same day at Quela gives 70 dead, 39 wounded and 21 prisoners, and two casualties in the company. The same day the Air Force went into action for the first time, with a PV-2 Harpoon from Luanda bombing the settlements that blocked the road north.2 sources2 sources

The Harpoons were maritime patrol aircraft whose crews had trained to hunt submarines. During the operation they flew 28 missions. The pilots' log books record machine-gun and bombing runs against what the crews identified as rebel concentrations; on 9 February one pilot dropped a 100-pound bomb near Marimba from 500 feet. Small Auster spotter planes based at Malanje joined in: on 18, 23 and 24 February army officers aboard them dropped hand grenades into crowds, which Cann says caused grave wounds.1 source1 source

A military intelligence bulletin of 28 February, quoted by Silva, lists PV-2 and T-6 aircraft bombing the areas of the posts of Quela, Cunda, Sunginge, Cambo, Cahombo, Bange-Angola, Marimba and Tembo Aluma, where large numbers of people had gathered. From 8 February the troops ran what they called “clean-up operations”. They ended, Silveira writes, in the death, imprisonment and punishment of many insurgents, among them the revolt's leaders; António Mariano died in prison in Bié.2 sources2 sources

When the 4th Company reached Tembo Aluma on the Cuango on 17 February, it found the village of Bumba, the Maholo king, freshly abandoned, with cooking pots still on the fires; the last villagers were climbing out of the river on the Congo side. Whole villages emptied into the bush or across the border. Many had killed their cattle, and after the operation the army had to bring in food to stop people starving.2 sources2 sources

Nobody counted the victims of the Baixa de Cassanje with care, and the regime worked to keep the whole affair quiet. The figures that exist come from people with very different vantage points, from the army that did the shooting to nationalist movements, missionaries and historians who worked from fragments.2 sources2 sources

The army's figure covers its own operation. Silveira's estimate also counts the victims of the political police. Freudenthal found that prisoners handed by the army and the posts to PIDE in Malanje, among them the alleged ringleaders, mostly disappeared from the record, and that there are signs of summary executions. Some survivors were sent to Luanda, where they disappeared into the wave of arrests and shootings that followed 4 February and 15 March.1 source1 source

Some accounts published abroad were harsher still. Mário Moutinho de Pádua, a Portuguese army doctor whose campaign diary appeared in Brazil in 1963, wrote that strikers near Malanje had been buried up to their necks and run over by tractors. Silveira quotes his testimony; none of the other sources used here repeats it. Cann rejects Pélissier's description of mass graves dug by bulldozers, arguing that no such machines worked in the Baixa during the rains.2 sources2 sources

By early March the growers were back at work. The army's staff summary for Salazar noted only that the rebel sobas had gradually given themselves up with their guns and that the area was “practically pacified from the military point of view”.1 source1 source

The Baixa was the first of three shocks to Portuguese Angola in 1961. On 4 February, while troops were moving into the Baixa, armed men attacked the prisons of Luanda to free political prisoners and seize weapons. On 15 March the UPA launched an uprising in the north, with massacres of white settlers and of Black workers on the farms that left thousands dead.2 sources2 sources

From April Salazar sent troops to Angola “quickly and in force”, and for Portugal this marked the start of thirteen years of colonial war. Despite the secrecy, refugees' accounts of Cassanje reached the United Nations, where they were used against Portugal in the debates on Angola that March.3 sources3 sources

Inside the regime, the Baixa was taken more seriously than Lisbon ever admitted. A report for the Ministry of the Overseas by the inspector Manuel Alfredo de Morais Martins, dated 7 March 1961, called it the “first large-scale subversive action in the overseas territories in the last forty years”, one that had grown beyond a reaction against cotton into “a true uprising against national sovereignty”.1 source1 source

The cotton system itself did not survive the year. Decree 43 639 of 2 May 1961, signed by President Américo Tomás, Salazar and the new Overseas Minister Adriano Moreira, made cotton growing free in the existing cotton zones and barred administrators from any role in it; Cann calls it corrective legislation that came four months too late. On 6 September 1961 the native statute was repealed and all natives of the colonies became, at least on paper, Portuguese citizens.3 sources3 sources

Independent Angola calls 4 January the Dia dos Mártires da Repressão Colonial, the Day of the Martyrs of Colonial Repression. Under its law on holidays of 16 February 2011 it is a date of national celebration, not a public holiday, alongside 15 March, the Day of the Expansion of the Armed Struggle. The 2018 revision kept it in that list; 4 February, the start of the armed struggle, is a holiday.2 sources2 sources

That ranking is itself contested. In 2022 the opposition parties UNITA and CASA-CE called for 4 January to become a public holiday, and CASA-CE's leader, Manuel Fernandes, said thousands of Angolans had died. Giselda Brito Silva, citing the Angolan historian Maria da Conceição Neto and others, argues that official memory has centred on the MPLA's 4 February, leaving the peasants of the Baixa and the UPA's 15 March in its shadow.2 sources2 sources

Each year the state holds a central ceremony in the region: at Quela in 2023, at Xá-Muteba in Lunda Norte in 2024, at Kiwaba Nzoji in 2025 and in Malanje in 2026, the 65th anniversary, when the defence minister, João Ernesto dos Santos, spoke and a wreath was laid at the Tomb of the Unknown Soldier. In 2024 a defence ministry official spoke of thousands of dead and of plans for a memorial in the Baixa, subject to the budget.4 sources4 sources

For decades Portugal said little about the Baixa. Franco Nogueira, Salazar's last foreign minister, wrote of some disturbances and attacks in north-west Angola, after which “the firm intervention of the security forces” restored calm. Silveira describes a curtain of silence that the regime tried, not wholly successfully, to draw over the events.1 source1 source

The drawers are now open. The Salazar archive and the PIDE files in the Torre do Tombo, Portugal's national archive in Lisbon, hold the army's intelligence summaries, the police reports and the Ministry of the Overseas inquiry. Aida Freudenthal used them in the late 1990s, and in 2012 Diogo Ramada Curto and Bernardo Pinto da Cruz read the inspector's report for what it reveals about colonial terror and colonial knowledge.2 sources2 sources

Portuguese historians still disagree about what the Baixa was. Anabela Silveira argues it went beyond a labour dispute to become the first armed rising against Portuguese sovereignty in the second half of the twentieth century. Valentim Alexandre's 2021 book, in Oliveira's reading, restores to the colonial reprisals of 1961 the weight that memories of the UPA's massacres had long crowded out. John P. Cann's account, published by the Portuguese Commission of Military History, counts 243 dead, calls the casualties relatively light and stresses the army's food aid.3 sources3 sources

Television and fiction have reached a wider public. Fernando Rosas's documentary for RTP in 2017 told of nearly twenty villages bombed with napalm and thousands dead, and Pedro Aires Oliveira counts Joaquim Furtado's RTP series A Guerra (2007 to 2012), which Alexandre cites and praises, among the most important efforts to bring the colonial reprisals of 1961 back into view. In A Outra Margem do Mar (2019), the novelist António Lobo Antunes, a former army doctor in Angola, has a senior officer, a district administrator and a planter's daughter look back on the crushing of the cotton workers' protest in the Baixa in January 1961.3 sources3 sources
