Why Portugal Colonized Guinea-Bissau

Portugal's colonization of Guinea-Bissau (formalized late 19th century, effective control early 20th) was driven by:

Economic Extraction

• Slave Trade (15th–19th c.): Cacheu and Bissau were major slaving ports; millions shipped to Brazil/Caribbean.
• "Legitimate" Commerce: Peanut (groundnut) boom mid-19th c.—became the colony's economic backbone.
• Resources: Timber, rubber, wax, ivory; later bauxite, phosphate (post-independence).

Geopolitical Strategy

• Scramble for Africa: Berlin Conference (1884–85) required "effective occupation." Portugal claimed the coast to block French (Senegal) and British (Gambia) expansion.
• Strategic Port: Bissau's deep-water estuary controlled the Geba River interior.

Ideological & Demographic

• Civilizing Mission: Catholic evangelization (Padroado); assimilation policy for *assimilados*.
• Settlement: Limited—mostly Cape Verdean administrators, traders, *lançados* (mixed-heritage traders).

Resistance was fierce (e.g., Bijagós, Balanta). PAIGC (Amílcar Cabral) led armed struggle 1963–74; independence declared 1973, recognized 1974 after Portugal's Carnation Revolution.
