The Second part of the royal commentary better known as the General history of Peru, is a historical literary work written by Inca Garcilaso de la Vega, the first Peruvian and Spanish mestizo of intellectual renown. It was published in 1617, in Córdoba, Spain, a year after the death of its author, and was dedicated to the Virgin Mary. It is the continuation of the Comentarios reales de los incas, and was published in a crucial period of the history of Peru, which began with the arrival of the Spanish and ended with the execution of the final Inca of Vilcabamba, Túpac Amaru I, in 1572. Aside from the historical motive of the text, the author sought through this second part of his work to praise his Spanish heritage, as he had done with his indigenous heritage in the first part of his work.

Inca Garcilaso de la Vega, born Gómez Suárez de Figueroa and known as El Inca, was a chronicler and writer born in the Viceroyalty of Peru. Sailing to Spain at 21, he was educated informally there, where he lived and worked the rest of his life. The natural son of a Spanish conquistador and an Inca noblewoman born in the early years of the conquest, he is known primarily for his chronicles of Inca history, culture, and society. His work was widely read in Europe, influential and well received. It was the first literature by an author born in the Americas to enter the western canon.
