The flag was first made by Gilbert Baker, to be used instead of the pink triangle symbol used before. The pink triangle was used by Nazis to show who was homosexual. Homosexual people were sent to concentration camps in Nazi Germany, where they made homosexual men wear a pink triangle. This was like the yellow Star of David that Jews had to wear to show who was Jewish. LGBT people were not ashamed of the pink triangle, but they wanted a more positive, happier symbol.
