What types of things did the Inca's trade?
the Inca traded things like gold silver and bronze
The Incas all lived in South America. The Maya had been a culture in Central America but that culture had collapsed before the Spanish arrived. The Aztecs ruled Mexico. In the past few years there have been some discoveries that some trade might have existed between the Aztecs and the Incas. No indication has surfaced of any trade between the Incas and Central America.
The Incas were fairly self-sufficient and trading was not a necessity. However, they did trade gold, silver, and cow leaf to the imperial capital, Cuzco, and other goods with local communities. They had no need to trade among themselves, so trade was always with outsiders. They sometimes traded their time, labor and knowledge for essential goods.
