Why were thousands of Kenyans placed in detention camps during the Mau Mau Rebellion?

During the Mau Mau Rebellion, British colonial authorities placed thousands of Kenyans—primarily from the Kikuyu ethnic group—into detention camps as part of a counterinsurgency strategy to suppress the militant nationalist movement.123

Following the declaration of a state of emergency in 1952, the British sought to dismantle the Mau Mau network, which had gained grassroots support by providing intelligence, food, and weapons to rebels hiding in the forests. During operations such as Operation Anvil in 1954, colonial forces screened residents to identify potential rebel loyalists. Mere suspicion of affiliation with the movement was sufficient grounds for incarceration, often for two years or more.2

These detention camps, which scholars have described as gulags, were used to isolate the population from the insurgents and break the movement's influence. The conditions within these camps were appalling, and detainees were frequently subjected to torture during interrogations. This mass detention was a central component of the British effort to regain control and suppress the uprising, which was driven by grievances over land dispossession, economic inequality, and political exclusion.21
