Since independence，African countries have gone through more than 60 years in the exploration of constitutional and legal systems. During this period，the constitutional and legal systems of African countries have experienced four periods including imitation，reform，transformation，and reshaping，each with corresponding institutional changes. In this process，African countries have basically realized the construction of citizens’ constitutional rights，the construction and distribution of power，and the appropriate restriction of administrative power. African countries have made great progress in constitutional democracy，but there are still some prominent problems. The causes for these problems include the decisive role of economic development，changes in domestic political forces，the development of social group forces，and excessive external interference，etc. African countries will continue to firmly follow the path of democracy，so the exploration of the model of public participation in the constitutional process，diversified constitutional management，the reform of the constitutional court and branches，and the improvement of the government system and electoral system will be the focus of reform in the future.
