This video from 2014 is a Forum panel style presentation from the State of Hidalgo, Mexico during the ceremonies about Mexican history in the XIX and XX centuries.
Unfortunately, is only in Spanish and without subtitles so hope our Spanish speaking forum members can enjoy and share any trivia mentioned here by the amazing professor and historian Dr Guadalupe Jimenez Colina. She is an authority and obtained her degree in the UK, often helping public government figures, on the independence of Latin America countries in the XIX century.
