On Sunday, America remembered Dr. Martin Luther King, Jr. who was assassinated in Memphis, Tennessee 42 years ago. In Senegal, West Africa, the country celebrated 40 years of independence from France.

It was during this celebration that Senegal's President Abdoulaye Wade called for unity between the 53-country continent.

He called for a "United States of Africa."

Wade addressed the crowd, which included 19 African leaders. He said, "The slave traders have left, the last colonist has left. We have no more excuses. We must seize this opportunity..."

The proposal of United States of Africa has been in the minds of many since the Pan-Africanism days, but it has never come to fruition.

Africa, a continent filled with rich minerals, is also considered the poorest.

It is said if the countries came together and uniified, poverty could be fought better.

President Abdoulaye, said "Only a politicial integration of the United States of Africa will shelter us from potentially fatal marginalization."
