Article: Hidalgo is hailed as the Father of the Nation even though it was Agustin de Iturbide and not Hidalgo who achieved Mexican Independence in 1821. Shortly after gaining independence, the day to celebrate it varied between September 16, the day of Hidalgo's Grito, and September 27, the day Iturbide rode into Mexico City to end the war. Later, political movements would favor the more liberal Hidalgo over the conservative Iturbide, so that eventually September 16, 1810 became the officially recognized day of Mexican independence. The reason for this is that Hidalgo is considered to be "precursor and creator of the rest of the heroes of the (Mexican War of) Independence." Hidalgo has become an icon for Mexicans who resist tyranny in the country. Diego Rivera painted Hidalgo's image in half a dozen murals. José Clemente Orozco depicted him with a flaming torch of liberty and considered the painting among his best work. David Alfaro Siqueiros was commissioned by San Nicolas University in Morelia to paint a mural for a celebration commemorating the 200th anniversary of Hidalgo's birth. The town of his parish was renamed Dolores Hidalgo in his honor and the state of Hidalgo was created in 1869. Every year on the night of 15–16 September, the president of Mexico re-enacts the Grito from the balcony of the National Palace. This scene is repeated by the heads of cities and towns all over Mexico. The remains of Miguel Hidalgo y Costilla lie in the column of the Angel of Independence in Mexico City. Next to it is a lamp lit to represent the sacrifice of those who gave their lives for Mexican Independence.

Question: Who was hailed as the Father of the Nation?

Hidalgo
