The Tang Dynasty.
Helped by the silk road this dynasty extended westward and was well connected to western culture like the Muslim and Byzantine Empires.
Founded after the end of Sui dynasty by the Li family around 600 the Tang empire lasted around 300 years only being briefly interrupted by the second Zhou dynasty.
The Tang Dynasty was located along the pacific coast of asia and west along the Silk road.
The Tang dynasty was very influential, especially on other Asian nations like Japan and Korea.The religion of Buddhism, which originated in India is and was practiced in Korea and Japan because of this dynasties influence. The idea of Respect for nature also affected these influenced cultures, even to the point that it helped develop the Japanese belief system of Shintoism! Confucianism, the beliefs and teachings of Confucius like the 5 relationships, was borrowed by these cultures. To this day the way of writing of the Chinese, Japanese and Korean's are similar because of the Tang dynasty.
The Tang dynasty also contributed many things that we still use today like block printing, porcelain, and the spinning wheel. A very important contribution from this dynasty was gun powder. It was probably discovered by alchemists seeking the elixir of immortality. Ironic seeing as how once this invention made its way to the west it was used in weapons. The Tang mostly used gun powder for fireworks, which was also invented during the tang dynasty, in celebrations and religious affairs though it might have been used to intimidate people before battle. The compass was also an invention of the Tang, though it was originally used to tell the future! Even the mechanical clock was invented during the tang dynasty! Invented around the year 725 by a man named Yi Xing the clock was powered by a giant water wheel to turn gears that moved the clock in accurate time.
