Kingdom of Cusco in the context of "Quechua languages"

Peru, officially the Republic of Peru, is a country in western South America. It is bordered to the north by Ecuador and Colombia, to the east by Brazil, to the southeast by Bolivia, to the south by Chile, and to the south and west by the Pacific Ocean. Peru is a megadiverse country, with habitats ranging from the arid plains of the Pacific coastal region in the west, to the peaks of the Andes mountains extending from the north to the southeast of the country, to the tropical Amazon basin rainforest in the east with the Amazon River. Peru has a population of over 32 million, and its capital and largest city is Lima. At 1,285,216 km (496,225 sq mi), Peru is the 19th largest country in the world, and the third largest in South America.

Peruvian territory was home to several cultures during the ancient and medieval periods, and has one of the longest histories of civilization of any country, tracing its heritage back to the 10th millennium BCE Caral–Supe civilization, the earliest civilization in the Americas and considered one of the cradles of civilization. Notable succeeding cultures and civilizations include the Nazca culture, the Moche, Wari and Tiwanaku empires, the Kingdom of Cusco, and the Inca Empire, the largest known state in the pre-Columbian Americas. The Spanish Empire conquered the region in the 16th century and Charles V established a viceroyalty with the official name of the Kingdom of Peru that encompassed most of its South American territories, with its capital in Lima. Higher education started in the Americas with the official establishment of the National University of San Marcos in Lima in 1551.

This is a chart of cultural periods of Peru and the Andean Region developed by John Rowe and Edward Lanning and used by some archaeologists studying the area. An alternative dating system was developed by Luis Lumbreras and provides different dates for some archaeological finds.

Most of the cultures of the Late Horizon and some of the cultures of the Late Intermediate joined the Inca Empire by 1493, but the period ends in 1532 because that marks the fall of the Inca Empire after the Spanish conquest. Most of the cut-off years mark either an end of a severe drought or the beginning of one. These marked a shift of the most productive farming to or from the mountains and tended to mark the end of one culture and the rise of another.

The Inca society was the society of the Inca civilization in Peru. The Inca Empire, which lasted from 1438 to 1533 A.D., represented the height of this civilization. The Inca state was known as the Kingdom of Cusco before 1438. Over the course of the empire, the rulers used conquest and peaceful assimilation to incorporate a large portion of western South America, centered on the Andes mountain ranges. The empire proved relatively short-lived however: by 1533, Atahualpa, the last Sapa Inca (emperor) of the Inca Empire, was killed on the orders of the conquistador Francisco Pizarro, marking the beginning of Spanish rule. The last Inca stronghold, the Neo-Inca State in Vilcabamba, was conquered by the Spanish in 1572.

Pachacuti Inca Yupanqui, also called Pachacútec (Quechua: Pachakutiy Inka Yupanki, pronounced [ˈpatʃa ˈkuti ˈiŋka juˈpaŋki]), was the ninth Sapa Inca of the Chiefdom of Cusco, which he transformed into the Inca Empire (Tawantinsuyu). Most archaeologists now believe that the famous Inca site of Machu Picchu was built as an estate for Pachacuti.

In Quechua, the cosmogonical concept of pachakutiy means "the turn of the world" and yupanki could mean "honorable lord". During his reign, Cusco grew from a hamlet into an empire that could compete with, and eventually overtake, the Chimú empire on the northern coast. He began an era of conquest that, within three generations, expanded the Inca dominion from the valley of Cusco to a sizeable part of western South America. According to the Inca chronicler Garcilaso de la Vega, Pachacuti created the Inti Raymi to celebrate the new year in the Andes of the southern hemisphere. Pachacuti is often linked to the origin and expansion of the cult of Inti.

The Sapa Inca (from Quechua: sapa inka; lit. 'the only emperor') was the monarch of the Inca Empire (Tawantinsuyu "the region of the four [provinces]"), as well as ruler of the earlier Kingdom of Cusco and the later Neo-Inca State at Vilcabamba. While the origins of the position are mythical and originate from the legendary foundation of the city of Cusco, it seems to have come into being historically around AD 1100. Although the Inca believed the Sapa Inca to be the son of Inti (the Sun god) and often referred to him as Inti churi "solar son" or Intip churin "son of the Sun", the position eventually became hereditary, with son succeeding father. The principal wife of the Inca was known as the coya or quya. The Sapa Inca was at the top of the social hierarchy, and played a dominant role in the political and spiritual realm.

Manco Capac, the first Inca monarch, adopted the title capac or qhapaq (roughly translated as "king"). Inca Roca, the sixth Inca monarch, was evidently the first to bear the title sapa Inca ("emperor") officially.
