Portugal and the Berlin Conference (1884–1885): The Scramble for Africa

Despite Portugal’s historical claim to the Congo region, the colonial ambitions of the great European powersBritain, France, and Germany—led to increasing disputes over African territories. In response, Portugal proposed an international conference to resolve its contested claim.

The resulting Berlin Conference (1884–1885), convened by Germany’s Otto von Bismarck, reshaped the future of African colonization. Instead of recognizing historical rights, the conference established the principle that a claim to African territory was only valid if the colonial power could demonstrate "effective occupation." As a result, the Congo was awarded to King Leopold II of Belgium, dashing Portugal’s hopes of securing the region.

The Partition of Africa and Portugal’s Colonial Holdings

While Portugal lost its claim to the Congo, the Berlin Conference formally recognized its control over:

  • Mozambique (East Africa)
  • Angola (West Africa)
  • Portuguese Guinea (modern-day Guinea-Bissau, West Africa)

Although Portugal retained a modest colonial empire, its holdings were now subject to the new European standard of effective control, forcing the Portuguese government to strengthen its administrative and military presence in these territories to maintain sovereignty. The Berlin Conference thus marked a turning point in European imperialism, accelerating the partition of Africa and intensifying the competition among colonial powers in the late 19th century.
