The history of Gabela is deeply rooted in Angola's colonial era and the golden age of the coffee industry. The town was founded by the Portuguese on September 28, 1907, and was originally known as N'Gabela. Its emergence and rapid growth were driven by the discovery of fertile lands in the South Kwanza province, which proved to be the perfect environment for coffee cultivation.
The defining factor for Gabela was its strategic position in the heart of one of the world's most productive regions for Robusta coffee. In the first half of the 20th century, the town evolved into a vital administrative and economic hub for numerous coffee estates, known as fazendas. The infrastructure built to harvest and transport the crop, including a narrow-gauge railway to the coast, made Gabela a primary link in the economy of colonial Angola.
Gabela's economy was almost entirely centered on the production and export of coffee. During the "coffee boom" of the mid-20th century, the town and its surroundings were among the most prosperous in the country. This prosperity attracted a large workforce and created a unique lifestyle where daily life followed the seasonal cycles of the harvest. The town’s architecture and layout still echo this era of "coffee gold," though subsequent historical shifts significantly changed the region's economic landscape.
