Kilwa was a city located in what is now Tanzania and was founded by people from Arabia and Persia. With the founders being Muslim, the location converted to Islam and spoke a mixed language of Arabic and local dialects.
Kilwa's position by the coast made it a great trade city where merchants exported items such as gold, copper and rhino horn and sometimes rulers even minted gold coins in foreign currencies so that people may trade more efficiently in the city.
The War Production Board was established in 1942 by the executive order of Franklin D. Roosevelt to regulate the production and allocation of materials and fuel during World War II in the United States.
