July 18th  – Death of Benito Juarez (Muerte de Benito Juárez)
On July 18th the Mexican flag is flown at half staff in accordance with the Law on the National Arms, Flag, and Anthem (Ley sobre el Escudo, Bandera y el Himno Nacionales) in remembrance of the Death of Benito Juarez (Muerte de Benito Juárez) in 1872.  

Days on which the flag is flown in remembrance of the passing of Benito Juarez are not Mexican federal statutory holidays; employees do not receive a day off (with or without pay).  Banks, businesses, government offices, and schools are open as usual.

He was to date the only Mexican president of pure pure indigenous blood.   IMO he was Mexico's second "George Washington" due the his reforms ending a political system not  far short of medivial fuedalism.

 
Benito Juárez
In many ways Mexico’s War of Independence, launched on September 16, 1810 by Manuel Hidalgo, was an armed struggle between the Peninsulars (those of pure Spanish blood born in Spain) and the Criollos (those of pure Spanish blood born in Mexico) for the economic and political control of Mexico.  It did little to improve the lives of the Mestizos (those of mixed Spanish and Indian blood) and the Amerindians (or Indians, the indigenous peoples born in the Americas).

Benito Pablo Juárez García (March 21, 1806 – July 18, 1872) was a Mexican attorney and politician of Zapotec origin from Oaxaca who served five terms as president of Mexico: 1858–1861 as interim president, and presidential terms of 1861–1865, 1865–1867, 1867–1871 and 1871–1872.  He resisted the French occupation; fought to overthrow Maximilian I who Napoleon III was instrumental in making Emperor of Mexico, restored the Republic, and used liberal reforms to modernize the country.  Juárez’s reforms were the triumph of Mexico’s liberal, federalist, anti-clerical, and pro-capitalist forces over the conservative, centralist, corporatist, and theocratic elements of the old colonial system.  As of this writing Benito Juárez is the only person of indigenous origins to have served as president of Mexico.  

The Reform (La Reforma) championed by Juárez represented the triumph of Mexico's liberal, federalist, anti-clerical, and pro-capitalist forces over the conservative, centralist, corporatist, and theocratic elements that sought to reconstitute a locally-run version of the old colonial system.  It replaced a semi-feudal social system with a more market-driven one, but following Juárez's death, the lack of adequate democratic and institutional stability soon led to a return to centralized autocracy and economic exploitation under the regime of Porfirio Díaz.  The Porfirist (Porfiriato) era, in turn, collapsed at the beginning of the Mexican Revolution that began in 1910.
