too bad that WWI and WWII chewed up so many Europeans.
population will expand to fill the vacuum.
The European powers had enough manpower between the World Wars to continue their hold on the colonies in Africa, the subcontinent and Southeast Asia. The European hold on Africa began to loosen in the 50s and 60s when “the winds of change” began to blow, and Africa exploded. There were a few peaceful transitions of power, and the occupying powers managed to leave their mark, culturally, on their former colonies.
