Descrição:

The Han Dynasty, which lasted from 206 BCE-220 CE was one of the longest of China’s dynasties. In terms of power and prestige, the Han Dynasty in the East rivaled the Roman Empire in the West. It lasted a span of over four hundred years, and was considered a peak in Chinese history especially in arts, politics, and technology. In 202 BCE, Emperor Gaozu, became the first Han emperor. He had already been king of Han since 206 BCE. During Han times, pulleys and wheelbarrows were invented and employed to move goods. To grind ores and grains, they employed the water-powered trip-hammer and air was pumped into furnaces due to the aid of bellows. By the end of the 1st century CE, one all of the Han emperor had died either young or without a chosen heir. When an emperor died without sons, a close relative, such as his cousin, was named emperor. In some cases, the new ruler was a child, in which case the real power was in the hands of a guardian from the family of the Empress since even infant rulers had to have an empress. This scenario led to all types of devious schemes in the court.
