Qin conquered rival states to form China's first unified empire. Zhou came before Qin; Han followed Qin. A dynasty is a line of rulers from the same family. *(drawing: The boxes show order, not how long each dynasty lasted.)* Qin rulers standardised written character forms, weights and measures, and built roads linking their lands. Shared writing helped officials who could read understand orders across regions. Common weights let officials and traders compare amounts using the same units. A grain-tax record could then be checked against records from another district. Matching units did not make every tax fair. Han rulers kept parts of Qin's system. Han rule lasted about four hundred years, with a break. Its capitals were Chang'an and later Luoyang. Officials kept records, sent reports and carried out orders. Armies fought and defended borders. Rulers used both officials and soldiers. Paper developed in China during Han times. People also wrote on bamboo and silk. Paper became useful for records and other texts. Papermaking later spread beyond China over many centuries. Han China and the Roman Empire existed during overlapping periods. Both had emperors and officials who helped govern distant regions. Both used armies to fight and defend borders. These shared features do not mean their governments worked in exactly the same way. **Example.** Terracotta means fired clay. Thousands of clay soldiers and horses were buried in pits near the First Qin Emperor's tomb. These statues were intended to protect him in the afterlife. **Recap.** Qin united rival states and set common standards. Han used officials, records and armies. Papermaking later spread beyond China. *Lesson, questions and flashcards written for this dataset.
