Answer:
Felix Longoria was significant to the Mexican American civil rights movement because he was a Mexican American veteran who was denied funeral services at a chapel by white cemetary officials.
Step-by-step explanation:
Felix Longoria was an American soldier who fought on the Pacific front of World War II, losing his life in the Philippines in 1945 in combat against the Japanese.
When his body was finally able to be repatriated in 1949, his family attempted to bury him in the local cementery of Three Rivers, Texas, where he had lived since birth. But the cementery authorities denied him this possibility, based on the racial segregation prevailing in the south in those years.
Although segregation in the south operated mainly against blacks, Mexicans and other Latinos were also discriminated against and segregated, but since their population numbers at that time were much lower, their cases did not take on significance.
Finally, Longoria was buried in Arlington National Cementery.
