Antisuyu
Antisuyu (Quechua: anti lit. 'east', suyu lit. 'quadrant'; Spanish: Antisuyo) was the eastern part of the Inca Empire which bordered on the modern-day Upper Amazon region which the Anti inhabited. Along with Chinchaysuyu, it was part of the Hanan Suyukuna or "upper quarters" of the empire, constituting half of the Tahuantinsuyu, the "four parts bound together" that comprised the empire.
