The newest African country is South Sudan, which gained independence from Sudan in 2011.
Up until 2011 Sudan had been the largest country in Africa. In July 2011 part of Sudan became independent to form a new country called the Republic of South Sudan, and making Sudan itself smaller. The result of this is that Algeria is now the largest country in Africa, and Sudan is now the third largest.
