Answer:
Many reasons can lead to the decline of empires and dynasties. One reason is that the form of government concentrates the wealth and power into one group of people. For example, kings and queens may give more to the nobles and the prosperous, but less to the poor. This generates uprisings and revolutions. Another reason is the lack of advancement. Some may not trade and build relationships with other nations, similar to ancient China, and lack resources and progress. This leads to their downfall as they do not have the proper technology to defend themselves against other nations. A third reason is that they expand their empire so much that they are unable to control it, losing border after border. Soon, they have nothing left except with what they started with. A fourth, and very common reason, is the fight for the throne. If the king, leader, or whoever is in charge loses their position or dies, many of the nobles that were close to that leader may fight over who is next in command. This leads to discord, allowing other nations to come and attack as they have no ruler to command their nation. A final reason is the shortage of wealth. Many kingdoms have contributed much to the known world but fell in a span of a few hundred years. This was most likely due to a shortage of wealth. They were unable to support the financial needs of the kingdom, as they suffered economically. Soon after, the kingdom would be in shambles.
