Islam reached Nigeria through the Borno Empire between (1068 AD) and Hausa States around (1385 AD) during the 11th century, while Christianity came to Nigeria in the 15th century through Augustinian and Capuchin monks from Portugal. The Songhai Empire also occupied part of the region. Lagos was invaded by British forces in 1851 and formally annexed in 1861. Nigeria became a British protectorate in 1901.
