Nezahualcoyotl, Acolhuan philosopher, warrior, poet and ruler (d. 1472)

Nezahualcoyotl (Classical Nahuatl: Nezahualcoyōtl [nesawalˈkojoːtɬ], modern Nahuatl pronunciation ) (April 28, 1402 – June 4, 1472) was a scholar, philosopher (tlamatini), warrior, architect, poet and ruler (tlatoani) of the city-state of Texcoco in pre-Columbian era Mexico. Unlike other high-profile Mexican figures from the century preceding Spanish conquest of the Aztec Empire, Nezahualcoyotl was not fully Mexica; his father's people were the Acolhua, another Nahuan people settled in the eastern part of the Valley of Mexico, on the coast of Lake Texcoco. His mother, however, was the sister of Chimalpopoca, the Mexica king of Tenochtitlan.

He is best remembered for his poetry, but according to accounts by his descendants and biographers, Fernando de Alva Cortés Ixtlilxóchitl and Juan Bautista Pomar, he had an experience of an "Unknown, Unknowable Lord of Everywhere" to whom he built an entirely empty temple in which no blood sacrifices of any kind were allowed — not even those of animals. However, he allowed human sacrifices to continue in his other temples.
