The purpose of this study is to examine the emergence of modernism as a cultural response to the conditions of modernity to change the way people live, work and react to the world around them. In this regard, the following tasks were formulated: 1) study the development of modernism on the world stage, 2) identify its universal features, and 3) analyze how the independence of Central and sub-Saharan Africa in the 1950s and 1960s coincided with a particularly bright period of modernist architecture in the region, when many young countries studied and asserted their identity in art. The article analyzes several objects of modernist architecture in Africa: urban development projects in Casablanca (Morocco), Asmara (Eritrea), Ngambo (Tanzania). The main features and characteristics of modernism which were manifested in the African architecture of the XX century are also formulated. It is concluded that African modernism is developed in line with the international modernist trend. It is also summarized that modernism which differs from previous artistic styles and turned out to be a radical revolution in art is their natural successor.
