Large empires emerged in 600 CE. Although Rome had fallen to nomadic Germanic tribes, it's latter half continued to prosper under a new name, The Byzantine Empire. The capital was later on re-named to "Constantinople" by the Roman emperor Constantine. In Eastern Europe, the city of Kiev became to capital of an empire combining Slavic and Scandinavian influences from the prosperous trade between the Baltic Sea (North) and Black Sea (South). The teachings of Muhammad allowed many followers to follow the religion Islam which then quickly spread to North Africa and South Asia. This led to centers of great intellectual achievement to be created in Baghdad and Spain. In Africa, there was now more trade across the Sahara and east coast of Africa which allowed more global trade. The revival of China from the Tang and Song dynasties resulted in greater prosperity and innovation. Even though India was often divided, it had unity and prosperity which allowed new trade-based empires to emerge in Southeast Asia. In the 1200's, the mongols - nomads who conquered land and were fierce-some warriors - created the largest land empire in human history. Even though the conquest came to great devastation, the unity of that great amount of land allowed trade to flourish again in Eurasia with technology and innovations spreading quickly.
