Han Dynasty

The common answer to these questions is the **Han Dynasty**, a significant period in Chinese history lasting from 206 BCE to 220 CE. 

### Explanation:

The Han Dynasty is a pivotal era in Chinese history, often considered a golden age for its advancements in culture, politics, and technology. Founded by Liu Bang, who became known as Emperor Gaozu, the Han Dynasty followed the short-lived Qin Dynasty. This dynasty solidified a centralized bureaucratic state and expanded the Chinese territory significantly.

Key points during the Han Dynasty include:

- **Military Conquests and Expansion**: The Han Dynasty expanded China's borders significantly through military campaigns. Notable figures like General Ma Yuan helped subdue regions such as Vietnam, defeating the Trưng Sisters' rebellion. The Han also repelled and negotiated with nomadic tribes like the Xiongnu.

- **Cultural and Technological Advancements**: The Han era saw significant contributions to culture and technology. Sima Qian's *Records of the Grand Historian* (Shiji) provides a detailed chronicle of early Chinese history up to his time. Inventor Zhang Heng created early seismometers, and notable works like the "Lessons for Women" by Ban Zhao emerged during this period.

- **Economic and Administrative Reforms**: The Han Dynasty established and managed monopolies on salt and iron and introduced the heqin marriage alliances to manage relations with frontier tribes. It also created an extensive network of commanderies and provinces to administer its vast territory.

- **Political Turmoil and Rebellions**: The Han period experienced internal strife and rebellion. Wang Mang’s usurpation led to a brief interruption in the dynasty (the Xin Dynasty). The later Eastern Han period saw significant uprisings like the Yellow Turban Rebellion, which contributed to the dynasty's eventual downfall.

- **Legacy**: The Han Dynasty's name is synonymous with the majority ethnic group in China, the Han Chinese, and the Chinese script (Hanzi) used today.
