Who made the terracotta warriors?

In China, the powerful Quin dynasty came to power in the 3rd century BC. They swiftly conquered their neighbors to make a large empire covering most of modern China. The Quin emperor Shi Huangdi standardized weights and measures and introduced a single form of currency. He is best remembered for his construction of the Great Wall of China. It was built to prevent raids from nomadic people in the north. When the emperor died, a huge tomb was built to hold his body. It was filled with a guardian army of thousands of life-sized terracotta (pottery) warriors. After the emperor's death the Qin empire broke up into a series of smaller states.
