In 1533 A.D., the Spanish arrived in South America. Hungry for territory and for converts to Christianity, the Spanish overwhelmed the Incan Empire. Their armies were no match for the far superior Spanish technologies. While the Incan Empire disappeared completely, the Incan people remained in the region. To this day, many descendants of the Incas still inhabit the nations of Chile, Bolivia, Peru, and Ecuador. These people still speak Quechua, the official Incan language, and still practice Incan culture.
There is no fence or hedge round time that has gone. You can go back and have what you like if you remember it well enough.
