Hispanic Heritage Month :The Mexican Repatriation

So September is Hispanic Heritage Month and so I thought I would post some stuff about that and this is what I found  a story about The U.S. deporting people of Mexican descent who were U.S. citizens to Mexico during the depression This was something called "Mexican Repatriation"
The Mexican Repatriation refers to a mass migration that took place between 1929 and 1939, when as many as two million people of Mexican descent were forced or pressured to leave the US. I had always heard roomer of this happening but I never actutully thought it was true but I was shocked to fined out this happened  
The Repatriation is not widely discussed in American history textbooks;^[4] in a 2006 survey of the nine most commonly used American history textbooks in the United States, four did not mention the Repatriation, and only one devoted more than half a page to the topic.^[4] Nevertheless, many mainstream textbooks now carry this topic. In total, they devoted four pages to the Repatriation, compared with eighteen pages for the Japanese American internment^[4] which, though also a gross violation of the rights of citizens, affected a much smaller number of people, even by the more conservative estimates for the Mexican deportations.^[1]
These actions were authorized by President Herbert Hoover and continued by FDR who was the 32nd President of the United States (1933–1945) and targeted areas with large Hispanic populations, mostly in California, Texas, Colorado, Illinois, and Michigan.
