Page "Isabel Moctezuma" Paragraph 6
Cortés valued Tecuichpotzin as a symbol of what he wished to portray as the continuity of rule between the Aztecs and the Spanish.
She was instructed in Christianity, converted to Catholicism, probably in 1526, and baptized as Isabel, the name by which she would thereafter be known.
Every indication is that Doña Isabel, the former Aztec princess Tecuichpotzin, was devout in her new religion.
Isabel ’ s education as a Christian did not include teaching her to read and she remained illiterate.
