Swahili culture is the product of the history of the coastal part of the African Great Lakes region.
By the 8th century, the Swahili people became involved in the Indian Ocean trade. As a consequence, they were influenced by the Arab, Persian, Indian and Chinese cultures.
As well as in the Swahili language, Swahili culture has a Bantu core and has also borrowed foreign influences. This Bantu expansion introduced the Bantu peoples in central, southern and southeastern Africa, regions of which they were previously absent. They gradually evolved to accommodate an increase in trade (mainly with Arab traders), population growth and even more centralized urbanization, developing what would later become known as the Swahili city-states.
As we can see Arab settlers particularly influential along the Swahili coast because they were the Bantu's major trading partner.
After WWI and during the Great Depression the US tried to be an Isolationist nation. They put out tariffs so people would buy US (forgetting that the rest of the world was still devastated by WWI (economies included)).
Contributions to the development of democracy.
The Chinese attempted to block its influence by building the great wall.
The Supreme Court has the power of judicial review, as developed in the case Marbury v. Madison.
Judicial Review means that if someone objects to an action of Congress, they can file a suit and that suit can work its way through the Federal Court system with the Judiciary making a determination if Congress has acted within its Constitutional purview.
