Many ethnic groups have tried to secede or break away from countries. Julius Nyerere in Tanzania would hold elections where people could choose candidates from one single party. In many nations the military has had to take over in order to create order. The military will often use harsh measures to stay in power. Those countries that have had the greatest success are those with stable governments. The government would own and control major businesses and other parts of the economy.

African nations are trying to promote the export of their own products. African traditions still encourage large families. Resources are becoming depleted.
