Marco Polo travelled through Asia and trade expanded across the Indian Ocean and Baltic Sea, setting the stage for greater expansion in the 15th century. The Native Americans of Cahokia, Mesoamerica and the Chimor State flourished while Mali, Ethiopia and Great Zimbabwe throve in Sub-Saharan Africa.
