The Sena people are an ethnic group, with origins in northwestern region of Mozambique in Tete Province, Manica Province, Sofala Province and Zambezia Province. They are also found in Malawi and Zimbabwe near their respective borders with Mozambique.
The Sena people's total population is around 2 million. It is estimated to be about 1.4 million in Mozambique, and about 0.5 million in Malawi. The Sena people in Malawi and Zimbabwe arrived from Mozambique and settled there in early 20th century as migrant laborers.
They speak the Sena language, also called Chisena or Cisena, which is a part of the Niger-Congo group of languages. The Sena language has many dialects.
Historically the autocephalous Sena people were those between the two large cultures of Shona people – a major ethnic group of Zimbabwe, and the Nyanja-Chewa people – a major ethnic group of Malawi and Mozambique. The Sena people have lived mainly in the Zambezi River valley. According to Isaacman, the Sena represent an admix of people, exhibiting "most, though not all, of the characteristics of Shona cultural groups".
After the arrival in 1498 of the Portuguese explorer Vasco da Gama on an Mozambique island in his search of a sea route to India, the colonial influence began on Sena and other ethnic groups in this part of Africa. Few years later, a storm hit a caravan of the ships of his countryman Pedro Álvares Cabral trying to repeat Vasco da Gama's voyage, separating them. Some ships reached modern Brazil, where they founded a Portuguese colony. Others went around the Cape of Good Hope in South Africa and reached Sofala, a Mozambique trading town with a busy gold market. Their reports triggered a gold rush and a commitment by Portugal king to settle Mozambique region where many ethnic groups including the Sena people lived. In 1514, Antonio Fernandez confirmed there were rich goldfields in middle Zambezi valley, the traditional home of Sena people, and the Portuguese interest in colonizing this region grew.
