The crisis of modernization of the 20th Century has primarily led to the growth of Islamic reform movements in many sub-Saharan African countries. As Africa began to modernize in the 20th century, many people began to feel that traditional forms of Islam were inadequate for addressing the challenges of modern life. Islamic reform movements emerged as a response to this crisis, seeking to modernize and adapt Islamic teachings to the needs of the modern world. These movements emphasized education, social justice, and the importance of Islamic values in everyday life. The crisis of modernization included the introduction of new technologies, colonialism, urbanization, and globalization, which all contributed to the need for a new approach to Islamic thought and practice.
