How was independence different for Kenya and Nigeria?

Nigeria and Kenya are two different parts of the world

Kenya gained its independence from Britain with Jomo Kenyatta as the country's first Prime Minister. The Union Jack was replaced by the black, red and green flag of the new nation. This followed the first all inclusive elections on 27 May 1963. A year later Kenya was declared a Republic. Lagos was invaded by British forces in 1851 and formally annexed in 1865. Nigeria became a British protectorate in 1901. Colonization lasted until 1960, when an independence movement succeeded in gaining Nigeria its independence.
