What was the main purpose of Shi Huangdi's centralization efforts in his empire?

The main purpose of Shi Huangdi's centralization efforts was to create a unified and standardized state. As the first emperor of China, he implemented several reforms aimed at consolidating power and enhancing the central authority of the state. These reforms included the standardization of weights and measures, currency, and even the writing system, which helped to facilitate trade, communication, and governance throughout the vast empire.

By centralizing authority, Shi Huangdi was able to reduce the power of regional lords and local fiefdoms, which previously operated with considerable independence. This unification was critical for maintaining control over a large and diverse population, ensuring that laws were applied uniformly, and strengthening the emperor's authority. The emphasis on standardization helped to lay the foundation for a cohesive national identity and efficient administration, which were essential for the stability and longevity of the imperial state.
