European colonisation in the context of "Portuguese conquest of Ceuta"

Slavery was widely practiced by the Indigenous peoples of the Americas, both prior to European colonisation and subsequently.

Slavery and related practices of forced labor varied greatly between regions and over time. In some instances, traditional practices may have continued after European colonisation.

Counterinsurgency (COIN, or NATO spelling counter-insurgency) is "the totality of actions aimed at defeating irregular forces". The Oxford English Dictionary defines counterinsurgency as any "military or political action taken against the activities of guerrillas or revolutionaries" and can be considered war by a state against a non-state adversary. Insurgency and counterinsurgency campaigns have been waged since ancient history. Western thought on fighting 'small wars' gained interest during initial periods of European colonisation, while modern thinking on counterinsurgency was developed during decolonization.

During insurgency and counterinsurgency, the distinction between civilians and combatants is often blurred. Counterinsurgency may involve attempting to win the hearts and minds of populations supporting the insurgency. Alternatively, it may be waged in an attempt to intimidate or eliminate civilian populations suspected of loyalty to the insurgency through indiscriminate violence.

The Berlin Conference of 1884–1885 was a meeting of colonial powers that concluded with the signing of the General Act of Berlin, an agreement regulating European colonisation and trade in Africa during the New Imperialism period. The conference of fourteen countries was organised by Otto von Bismarck, the first chancellor of Germany, at the request of Leopold II of Belgium at a building (No. 77, now No. 92) on Berlin’s central Wilhelmstrasse. It met on 15 November 1884 and, after an adjournment, concluded on 26 February 1885 with the signing of the General Act. During the conference, attendees also discussed other related issues and agreed on a common framework for the recognition of European ''effective occupation'' of African coastal territory elsewhere on the continent. After the conference, the pace of European claims being made on African territory increased, part of the Scramble for Africa that had already begun.

The General Act of Berlin can be seen as the formalisation of the Scramble for Africa that was already in full swing. The conference contributed to ushering in a period of heightened colonial activity by European powers, and is sometimes cited as being responsible for the "carve-up of Africa". However, some scholars warn against overstating its role in the colonial partitioning of Africa, drawing attention to the many bilateral agreements concluded before and after the conference. A 2024 study found that the only borders set at the conference were those of the Congo region (and these were subsequently revised), and that most of Africa’s borders did not take their final form until over two decades later. Wm. Roger Louis conceded, however, that "the Berlin Act did have a relevance to the course of the partition" of Africa.
