Answer:
Explanation:
<u>Economic Obstacles</u>
- After the national road was built, they later on started making railroad tracks, but had to stop, due to budget problems.
- in 1816 when the second national bank was invented, tariffs taxed imported goods at a 25% rate. American consumers noticed that the the cost of their goods increased drastically.
<u>Physical Obstacles: Transportation </u>
- One of Henry Clay's struggles while;e having the American System, was transportation.
- During the early 1800's, cars and trains were not invented yet
- People traveled by horse or carriage, pulled by cattle or horses
- The terrain and different land regions that traders and travelers faced were difficult, especially ground that was wet and muddy.
Mongol leader Genghis Khan (1162-1227) rose from humble beginnings to establish the largest land empire in history. After uniting the nomadic tribes of the Mongolian plateau, he conquered huge chunks of central Asia and China. ... Genghis Khan died in 1227 during a military campaign against the Chinese kingdom of Xi Xia.
Unifying the Mongols was no small achievement — it meant bringing together a whole series of disparate tribes. Economically the tribal unit was optimal for a pastoral-nomadic group, but Chinggis brought all the tribes together into one confederation, with all its loyalty placed in himself.
