The chronicles say Nezahualcóyotl had his bride's betrothed killed in battle, executed their son for treason, and named a 7-year-old heir on his deathbed

This is the account of the 17th-century chroniclers Alva Ixtlilxóchitl and Torquemada, as assembled by José Luis Martínez. Nezahualcóyotl ruled Texcoco from 1431. About 1443 his vassal Cuacuauhtzin, lord of Tepechpan, had a girl named Azcalxochitzin serve him at dinner. Cuacuauhtzin was raising her to be his wife; her parents had given her to him as a child in 1440 for gold, feathers and slaves. The chronicles say Nezahualcóyotl asked the Tlaxcalans to kill Cuacuauhtzin in the next "flower war" and told two of his own captains to put him where he would not come back. Cuacuauhtzin composed songs of farewell and was cut to pieces in battle in 1443. Nezahualcóyotl married Azcalxochitzin. Their son Tetzauhpiltzintli, his first legitimate son, was called a fine poet and soldier. About 1464 a half-brother, Eyahue, accused him of rebellion. The chronicles say Eyahue's mother, a royal favourite, wanted her sons in the succession, and that the charge was probably false. Tetzauhpiltzintli was condemned under his father's own laws and executed. On 1 January 1465 the queen bore another son, Nezahualpilli. In 1472 the dying king hid the 7-year-old under his royal robes while the ambassadors of Mexico and Tlacopan spoke, then had the boy repeat everything said. Nezahualpilli ruled Texcoco until shortly before the Spaniards came.
