Problem: Kublai Khan did not conquer the Song dynasty in South China until 1279, so Tibet was a component of the early Mongol Empire before it was combined into one of its descendant empires with the whole of China under the Yuan dynasty (12711368). Van Praag writes that this conquest "marked the end of independent China," which was then incorporated into the Yuan dynasty that ruled China, Tibet, Mongolia, Korea, parts of Siberia and Upper Burma. Morris Rossabi, a professor of Asian history at Queens College, City University of New York, writes that "Khubilai wished to be perceived both as the legitimate Khan of Khans of the Mongols and as the Emperor of China. Though he had, by the early 1260s, become closely identified with China, he still, for a time, claimed universal rule", and yet "despite his successes in China and Korea, Khubilai was unable to have himself accepted as the Great Khan". Thus, with such limited acceptance of his position as Great Khan, Kublai Khan increasingly became identified with China and sought support as Emperor of China.
Where did Khubilai seek support as Emperor?

Problem: People of German origin are found in various places around the globe. United States is home to approximately 50 million German Americans or one third of the German diaspora, making it the largest centre of German-descended people outside Germany. Brazil is the second largest with 5 million people claiming German ancestry. Other significant centres are Canada, Argentina, South Africa and France each accounting for at least 1 million. While the exact number of German-descended people is difficult to calculate, the available data makes it safe to claim the number is exceeding 100 million people.
How many people of German decent live in the Americas?
