What role did al hajji umar play in jihad wars?

Al Hajji Umar, also known as Umar al-Futi, was a prominent West African Islamic leader and military commander during the 19th century. He played a crucial role in the jihad wars by leading a series of Islamic reform movements against both local pagan practices and colonial powers, particularly in present-day Senegal, Mali, and Guinea. His campaigns aimed to establish a purer form of Islam and expand the influence of Islamic governance in the region. Umar's efforts contributed significantly to the spread of Islam and the establishment of various Islamic states in West Africa.
