Jani Beg
In 1344, Jani Beg tried to seize Caffa from the Genoese but failed. In 1347, he signed a commercial treaty with Venice. The slave trade flourished due to strengthening ties with the Mamluk Sultanate. Growth of wealth and increasing demand for products typically produce population growth, and so it was with Sarai. Housing in the region increased, which transformed the capital into the center of a large Muslim Sultanate.
