Conflict grew because the Taira held much power. In 1179, the Taira took over government posts. They removed their rivals from power. This made the Minamoto very angry. In 1180, a call to arms was sent out. This was led by Prince Mochihito and Minamoto no Yorimasa. The fighting began near the Uji River.

This early battle was very dramatic. It set the stage for years of fighting.

Many battles happened across the country. Minamoto no Yoritomo took over leadership of his clan. He traveled to find allies. He faced many hard jobs along the way. In 1181, Taira no Kiyomori died from illness. A famine also hit Japan during this time.

The war paused for nearly two years. Then, it started again in 1183. The Minamoto forces began to win more fights. They pushed the Taira out of the capital city, Kyoto.

The Taira fled to the west. They used their ships to stay safe.
