During most of the 17th century, Spanish ships were menaced by pirates, so they developed a complex system where ships with military protection were dispatched to Central America in a convoy from Seville the only port allowed to trade with the colonies, to Lima, Peru and from it to the inner cities of the viceroyalty.

The 1687 Peru earthquake destroyed most of the city buildings; the earthquake marked a turning point in the city's history as it coincided with a trade recession and growing economic competition with cities such as Buenos Aires.
