This chapter discusses three syndromes, each of them converging with a particular era: a sanitation syndrome (1920-1940), a development syndrome (1940-1960) and a cooperation syndrome (1960-1980). While thus presenting a chronological overview of Kinshasa's history of urban planning, the use of syndromes will bring to the fore strong continuities in urban planning policies and practices, despite important ruptures in Congo's history, in particular its gaining of independence in 1960. The book presents an overview of Congo's urban planning history: from the first planning experiments to the large masterplans of the late colonial years. By focusing on the export of metropolitan planning concepts to the colony, in Kinshasa as well as other urban centers in Congo, the book not only sketches the outlines of Congo's urbanization before 1960, it above all offers an important addition of Belgium's canonical urban planning history. The rapid urban growth of Kinshasa made the 1967 masterplan obsolete the very moment it was published.
