Thus, although Huayna Capac named the infant Ninan Cuyochi as his first heir, sources differ as to whether the boy died first, was unacceptable because of an unfavorable divination, or even if Huayna simply forgot that he had named him when asked to confirm the nomination. In any event a second choice was requested and again sources vary. He may have named Huáscar half-brother Atahualpa who then refused, or named Huáscar himself, or perhaps even the nobles put forward Huáscar. Whatever the truth, the result of Huáscar's accession and the dispute over it before and after led to civil war between Huáscar (made Emperor by a faction based in Cuzco) and Atahualpa (backed by leaders who were based in the north with Huayna).§≈≠±±≤ÄãÄ′°°°°°
Document 6: Pre-Columbian Bolivia: Pre-Columbian Bolivia covers the historical period between 10,000 BCE, when Upper Andes region was first populated and 1532, when Spanish conquistadors invaded Inca empire. The Andes region of Pre-Columbian South America was dominated by the Tiwanaku civilization until about 1200, when the regional kingdoms of the Aymara emerged as the most powerful of the ethnic groups living in the densely populated region surrounding Lake Titicaca. Power struggles continued until 1450, when the Incas incorporated upper Bolivia into their growing empire. Based in present-day Peru, the Incas instituted agriculture and mining practices that rivaled those put in place many years later by European conquerors. They also established a strong military force and centralized political power. Despite their best efforts, however, the Incas never completely controlled nomadic tribes of the Bolivian lowlands, nor did they fully assimilate the Aymara kingdoms into their society. These internal divisions doomed the Inca Empire when European conquerors arrived.

In 1527 Pizarro and his men were waiting on the Isla del Gallo, in bad conditions, when the supply ship returned from Panama with orders from the Spanish governor to abandon the expedition. According to the traditional version of the story, Pizarro drew a line in the sand with his sword and said, "those on that side of the line can go back to Panama and be poor; those on this side can come to Peru and be rich. Let the good Castillian choose his path." In the traditional telling of the story, only thirteen men chose to stay with Pizarro.

In response to this threat, one of Abu Yaqub's first acts was to reach agreement on a fresh treaty with the Nasrid ruler Muhammad II of Granada, ceding all Marinid possessions in Spain, with the exception of Algeciras, Tarifa, Ronda and Guadix.
