The Berlin Conference and the Anglo-Portuguese Crisis of 1890
from The Berlin Conference: How Africa Was Partitioned — Fexingo History · host Fexingo
In Episode 67 of our Berlin Conference series, Lucas and Luna explore the Anglo-Portuguese Crisis of 1890, a little-known flashpoint that nearly brought Britain and Portugal to war over a strip of land in southern Africa. They follow the story of Portugal's 'Rose-Colored Map' (Mapa Cor-de-Rosa), a colonial dream linking Angola to Mozambique across the very territory the British wanted for their Cape-to-Cairo railway. The episode centers on the British ultimatum of January 11, 1890, delivered by Lord Salisbury, which forced Portugal to abandon its claims. We meet key figures: Portuguese King Carlos I, Prime Minister José Luciano de Castro, and British colonialist Cecil Rhodes. The crisis spurred Portugal's 1890 Lisbon riots and the rise of republican sentiment, while also cementing British dominance over central Africa. Lucas explains how the General Act of Berlin's 'effective occupation' clause was used by Britain to justify its demands, and how Portugal's weak hold on the interior left it vulnerable. The episode also touches on the role of the mixed-commission boundary surveys and the legacy of the 1891 Anglo-Portuguese Treaty that finally settled the borders. A fresh angle on the Berlin Conference's geopolitical aftershocks. #BerlinConference #AngloPortugueseCrisis1890 #MapaCorDeRosa #CecilRhodes #LordSalisbury #PortugalAfrica #CapeToCairo #BritishUltimatum #1890LisbonRiots #KingCarlosI #JoséLucianoDeCastro #ColonialAfrica #EffectiveOccupation #ScrambleForAfrica #History #FexingoHistory #Imperialism #BoundarySurvey Keep every episode free: buymeacoffee.com/fexingo
