One of the weaknesses of dynastic model is that there is not any time given for the rulers who have gone weak. Each and every rule has some good and bad phases. There may be a scenario when one of the rules is strong, while at another time they may be weak. Once it was identified that there were significant number of problems in the rule, the dynasties were removed and a new rule came up for the rule. Thus, the compilation of the rule was completely error free. Many a times, a deserving ruler may have to vacate his rule just for a weak phase. A leader, who was stronger than the other one, may proclaim the mandate and establish his own dynasty. Another weakness of Dynastic model is that the judgment was also based on natural disasters. If a natural disaster has been observed in the place, ruler had to give up his dynasty and lose the mandate of heaven. It was because of the weak dynastic rule that Europeans were able to attack in China and occupy the lands.
Dynastic model was a successful model which had been running in China for a long time and been successfully implemented for years. It was because of Dynastic model that a dynasty could lead peacefully for a number of years. The very first dynasty in China was Zia which were succeeded by Shang. Some of the most powerful dynasties included the names of Han and Tang. These periods were generally considered to be the stronger periods. Also, when the situation of crises was observed, there was a ruler who emerged and helped in the unification of the nation. After the rule of Han dynasty in China, it was Yang Jian who unified the nation and established the Sui Dynasty. Thus, the split was eventually followed by the condition of unification. Also, the rulers who were the part of this cycle looked after their people. The rulers ensured that the people are secured from the harms which have been caused by the outsiders. There are a number of examples where the rulers performed a number of reforms.
