Once upon a time, Ilmen Slavs lived near the shores of Lake Ilmen. They built Veliky Novgorod, which was first mentioned in the chronicle in 859. Convenient waterways contributed to the development of trade links of Novgorod. By the end of the X century Novgorod had become a rich trading city. Fur and leather, wax and honey, flax, lard, walrus tiles were exported to Western Europe. The rich and active population of Novgorod limited the prince’s power. Rich boyars were the lords in Novgorod and ruled it themselves. Their arbitrariness sometimes caused rebellions in a city inhabited by craftsmen: masons, potters, shoemakers, gunsmiths, etc. Internal struggle weakened Novgorod.
