For the history part on your question: Africa was the first continent outside of Asia that Islam spread into, in the early 7th century. It first came to Africa with Muslim refugees fleeing persecution in the Arab peninsula. This was followed by a military invasion, some seven years after the death of the prophet. Islam quickly spread west from Alexandria to pockets in Egypt, Nubia and Ethiopia.
For the impact part of your question: After the death of the Prophet, 100 years after, between the 8th and 9th centuries Arab traders and travelers began to spread the religion along the eastern coast of Africa. So, Islam impacted the continent very greatly, from the establishment of mosques to many other different factors.
