Best answer: C. Hitler and the Nazis were able to exploit the economic hardships and racism of Germany.
Context/details:
After the Great War (World War I), Germany was required to pay heavy reparations payments to Britain and France. Meanwhile, Britain and France owed repayment of funds to the United States for borrowing they had done during the war. So the United States had been supporting Germany in the 1920s with loans. When the USA could no longer afford to extend loan monies to Germany after the stock market crash of 1929, that sent Germany's economy spiraling even deeper into the Depression than was felt in the United States.
The bad situation in Germany made it possible for a radical leader like Hitler, making all sorts of bold promises, to win over enough people to rise to power. Hitler also used racial prejudice to blame the Jews for Germany's problems, leading to a campaign of persecution against the Jewish people in Germany. Hitler promised a return to national greatness and fiercely rebuilt Germany as a military machine. The rise of Hitler and the Nazis brought about World War II in Europe, and the racism of their movement brought about the Holocaust.
According to Al Bakri, Kumbi Saleh (Ghana) consisted of two towns. In one town lived the arabs, it held twelve mosquets and numerous wells of sweet water. In this town lived learned men, as well as jurists and religious men. Six miles away laid the city where the king lived (Al Ghaba), in a palace surrounded by a defensive wall.
Only the king and his heir could wear sewn clothes and other accessories, signs of wealth, while the common people that followed his religion could only dress with simplicity, shaving their beards and hair. The king's way of living would exude power, wealth and magnificence, and his followers could only show humility by kneeling and sprinting their heads with dust. While the arabs would greet him by clapping.
As I understand it, the customs in arab lands were much more equal, there were not big social differences between its inhabitants. In the other part of the city, this was not the case, there would be big social differences between the king and its followers, that the author doesn't name bi its etniciti, nationality or religion. They were just the followers of the king.
