On January 3, agricultural workers employed by Cotonang, a Portuguese-Belgium cotton plantation company, staged a protest to force the company to improve their working conditions. The protest, which later became known as the Baixa de Cassanje revolt, was led by two previously unknown Angolans, António Mariano and Kulu-Xingu. During the protest, the Angolan workers burned their identification cards and physically attacked Portuguese traders on the company premises. The protest led to a general uprising, to which Portuguese authorities responded with an air raid on twenty villages in the area, killing large numbers of Angolan villagers.
After independence from Portugal in 1975, the Angolan government designated February 4 a national holiday, "Colonial Repression Martyrs Day," in 1996 in remembrance of the attack. To the Angolan people, this date continues to inspire different generations of Angolan children in their actions in defence of liberty and well-being. (AllAfrica.com)
