Qin Shihuangdi Unifies China
In 221 B.C.E., the ruler of the Qin state completed the conquest of all rival Chinese kingdoms and declared himself Qin Shihuangdi, meaning “First Qin Emperor,” creating a unified China for the first time. To consolidate his empire, he standardized writing, currency, weights, and measurements across the entire territory. He ruled through Legalist principles — absolute power backed by harsh laws. His most lasting monument was ordering the connection of existing walls into what became an early version of the Great Wall. This 6th grade history topic is in Chapter 8 of IMPACT California Social Studies, Grade 6.
