The changing relations between churches in Africa and Europe occupy an essential position in the history of Christianity in the 20th century. Major turning points in the "age of extremes" are involved: the impact of two world wars for the people of the African continent, the process from colonial rule to decolonization, and the division between East and West in Europe with its repercussions for the North-South relationship; nor may the historian disregard the strenuous coexistence of Christians with non-Christians. The over-all pattern of which these changes and challenges form part, it is the objective of the essays in this volume to delineate. Their authors come from various parts of Africa and North-Western Europe, and the project is part of a long-term strategy to promote trans-continental dialogue and cooperation.
