Neo-Inca State in the context of "Manco Inca Yupanqui"

The Inca Empire, officially known as the Realm of the Four Parts (Quechua: Tawantinsuyu pronounced [taˈwantiŋ ˈsuju], lit. 'land of four parts'), was the largest empire in pre-Columbian America. The administrative, political, and military center of the empire was in the city of Cusco. The Inca civilisation rose from the Peruvian highlands sometime in the early 13th century. The Portuguese explorer Aleixo Garcia was the first European to reach the Inca Empire in 1524. Later, in 1532, the Spanish began the conquest of the Inca Empire, and by 1572 the last Inca state was fully conquered.

From 1438 to 1533, the Incas incorporated a large portion of western South America, centered on the Andean Mountains, using conquest and peaceful assimilation, among other methods. At its largest, the empire joined modern-day Peru with what are now western Ecuador, western and south-central Bolivia, northwest Argentina, the southwesternmost tip of Colombia and a large portion of modern-day Chile, forming a state comparable to the historical empires of Eurasia. Its official language was Quechua.

The Incas were most notable for establishing the Inca Empire which was centered in modern-day Peru and Chile. It was about 4,000 kilometres (2,500 mi) from the northern to southern tip. The Inca Empire lasted from 1438 to 1533. It was the largest Empire in America throughout the Pre-Columbian era. The Inca state was originally founded by Manco Cápac in the early 1200s, and is known as the Kingdom of Cuzco. Under subsequent rulers, through strategic alliances and conquests, it expanded beyond Cusco and into the Sacred Valley. Their territory then rapidly grew under the 9th Sapa Inca (emperor), Pachacuti and his descendents.

Over the course of the Inca Empire, the Inca used conquest and peaceful assimilation to incorporate the territory of modern-day Peru, followed by a large portion of western South America, into their empire, centered on the Andean mountain range. However, shortly after the Inca Civil War, the last Sapa Inca of the Inca Empire, Atahualpa, was captured and killed on the orders of the conquistador Francisco Pizarro, marking the beginning of Spanish rule. The remnants of the empire retreated to the remote jungles of Vilcabamba and established the small Neo-Inca State, which was conquered by the Spanish in 1572.

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.

Don Martín García Óñez de Loyola (c. 1549 – December 24, 1598) was a Spanish-Basque soldier and Royal Governor of Colonial Chile. He was the grand-nephew of Saint Ignatius of Loyola, the founder of the Jesuits.

Óñez de Loyola first gained renown by capturing Inca leader Túpac Amaru, which put an end to the Neo-Inca State. He later fought in the Arauco War after being appointed the Governor of Chile. He was defeated and killed by Mapuche warriors at the Battle of Curalaba, which paved the way for the Destruction of the Seven Cities.

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.

Vilcabamba (in Hispanicized spelling) or Willkapampa (Aymara and Quechua), often called the Lost City of the Incas, is a lost city in the Echarate District of La Convención Province in the Cuzco Region of Peru. Vilcabamba, in Quechua, means "sacred plain". The modern name for the Inca ruins of Vilcabamba is Espíritu Pampa (Plain of the Spirits).

Vilcabamba was the capital of the Neo-Inca State from 1539 to 1572. The Neo-Inca State was the last refuge of the Inca Empire until it fell to the Spaniards and their indigenous allies in 1572, signaling the end of Inca resistance to Spanish rule. Subsequently, Vilcabamba was abandoned and its location forgotten. In 1911 explorer Hiram Bingham mistakenly identified the abandoned ruin of Machu Picchu as Vilcabamba, but he also visited a ruin called Espiritu Pampa by local Peruvians. In 1964, Gene Savoy identified Espiritu Pampa as the fabled Vilcabamba, a designation widely accepted by archaeologists and historians.
