This great city was an important centre for merchants from around the world. The brothers traded busily here for six years and bought a lot of jewels. But after some fighting between different groups in the city, the Polos decided to leave and take their jewels with them.
The brothers first sailed to Sudak in modern-day Ukraine. They wanted to return to Venice but travel from here was too dangerous. So they began to move east along the north route of the Silk Road. The roads were safer in this area because they were under the rule of the Mongols. On the journey the brothers and sold good like salt, animal skins, gold , and spices.
