Spain and then Mexico paid Moctezuma's heirs for Tacuba lands until a 1934 decree, and a Spanish dukedom still carries his name

After Tenochtitlan fell, Spain granted Moctezuma II's daughter Isabel perpetual ownership of lands that included Tacuba. Chroniclers counted more than 300 towns there. Her descendants received payments for the use of those lands for the 300 years of Spanish rule, and independent Mexico continued them. UNAM historian Alejandro González Acosta puts the payment at 1,480 grams of gold, about 2.7 million pesos today. AFP estimated it at 60,000 to 90,000 dollars a year. President Abelardo L. Rodríguez ended the payments by decree. N+ dates the decree 9 February 1934, and La Jornada gives 8 January 1934. The heirs filed an amparo. Mexico's Supreme Court ruled that the payments were a civil contract, and the heirs lost. Descendants tried again in 1991 and 2003 and failed. In Spain, a great-grandson of Moctezuma received the title of count in 1627, and the line later held a dukedom. The title Duke of Moctezuma de Tultengo dates from 11 October 1865^†. On 18 December 2013 Spain ordered a Royal Letter of Succession in the dukedom, with Grandeza de España, for Juan José Marcilla de Teruel-Moctezuma y Valcárcel. In 2021 the duke rejected President López Obrador's demand that Spain apologize for the conquest. Another branch holds the title Count of Miravalle. Moctezuma's descendants number in the hundreds. They include Esteban Moctezuma, Mexico's ambassador to the United States in 2021.
