The Pink Map: areas claimed by Portugal before the Ultimatum.

Map showing incomplete British control of the Cape to Cairo route, 1913.

On 20 August 1890 the Treaty of London was signed between Portugal and the United Kingdom, defining the territorial limits of Angola and Mozambique. The treaty was published in the Di rio do Governo (Portugal's Government Diary) on 30 August and presented to the parliament that same day, leading to a new wave of protests and the downfall of the Portuguese government. When this treaty was not ratified, a new treaty was afterwards negotiated and accepted by both governments the following June. This ultimatum was one of the main causes for the Republican Revolution, which ended the monarchy in Portugal 20 years later.
