Answer:
World War II.
Step-by-step explanation:
Hector P. Garcia was a Mexican- American physician, a surgeon who was also part of World War II. His experience during and after the war led to his immense fight for the rights of his people, especially war veterans.
The strongest influence that affected Garcia's fight for civil rights was the Second World War. Despite the equal participation of troops from various races and backgrounds, Garcia found that the American society still is partial and discriminatory against nonwhites, be it Hispanic or even African. So, he dedicated his life fighting to get equal rights and facilities to his people, the Hispanic community. He would also found the American G.I. Forum which focuses on the issues of veterans, especially of the Hispanic community.
