Mexican War of Independence
Although Mexico gained its independence in September 1821, the marking of this historical event did not take hold immediately. The choice of date to celebrate was problematic, because Iturbide, who achieved independence from Spain, was rapidly created Emperor of Mexico. His short-lived reign from 1821–22 ended when he was forced by the military to abdicate. This was a rocky start for the new nation, which made celebrating independence on the anniversary of Iturbide's Army of the Three Guarantees marching into Mexico City in triumph a less than perfect day for those who had opposed him. Celebrations of independence during his reign were marked on September 27. Following his ouster, there were calls to commemorate Mexican independence along the lines that the United States celebrated in grand style its Independence Day on July 4. The creation of a committee of powerful men to mark independence celebrations, the "Junta Patriótica", organized celebrations of both September 16, to commemorate Hidalgo's grito and the start of the independence insurgency, and September 27, to celebrate actual political independence.
Mission Dolores Park
Until after World War II, the Mission District was largely inhabited by European Americans, which from the 1950s to the 1970s were replaced by an influx of Latino immigrants. Partly as a symbol of this transformation, on 16 September 1966 a replica of the “Mexican Liberty Bell”, presented by Mexican president Gustavo Díaz Ordaz, was installed in the park near a statue of Miguel Hidalgo, the father of Mexican independence, which had been erected four years earlier. The "Mexican Liberty Bell" (today located in the National Palace in Mexico City) is a church bell that Hidalgo rang in 1810 in the Mexican city of Dolores Hidalgo, in what became known as the "Cry of Dolores" (El Grito de Dolores) that launched the Mexican War of Independence. In 2014, the replica was relocated by around 25 feet during the renovations of Mission Dolores Park.
