The Khitan were a nomadic people who originated in what is now northeastern China. They established the Liao Dynasty in the 10th century, which lasted until the 12th century. The Khitan were known for their horse-riding skills and military prowess, which allowed them to control vast territories and interact with various neighboring cultures. The Khitan developed their own script, known as the Khitan script, which was used for writing their language. They played a significant role in the history of East Asia, influencing the cultures of China, Mongolia, and Korea. Their legacy is evident in the historical interactions between these regions.
