The original title of Count of Moctezuma, from which it descends, was given by King
Philip IV of Spain in 1627 to
Pedro Tesifón Moctezuma de la Cueva, 1st
Viscount of Ilucán,
Lord of Tula and Peza, a
Knight of Santiago and a great-grandson of Moctezuma II through his son
Pedro de Moctezuma Tlacahuepan and grandson
Diego Luis Moctezuma (Ihuitl Temoc), Pedro Tesifón Moctezuma de la Cueva's father, who went to Spain.
Charles II of Spain later granted the second holder of this title the qualification of
de Tultengo, in reference to a town in the Mexican state of
Hidalgo which was part of the inheritance of Moctezuma's son Pedro. All subsequent holders from 1635-1865 used the title, "Count of Moctezuma de Tultengo" until the advancement to the rank of Duke removed
de Tultengo. The title of Duke of Moctezuma (without the qualification of 'de Tultengo') was granted to Antonio María Marcilla de Teruel-Moctezuma y Navarro, 14th Count of Moctezuma de Tultengo and 11th Marquis of Tenebrón on October 11, 1865 by Queen
Isabella II of Spain. The current holder of the title is
Juan José Marcilla de Teruel-Moctezuma y Valcárcel, 6th Duke of Moctezuma. His father had assumed the title, and was regranted the qualification of
de Tultengo (as the second Count of Moctezuma was in 1639) by King
Juan Carlos I of Spain in 1992. == List of holders ==
