What symbol did the gypsies have to wear during World War 2?

During World War II, the Romani people, often referred to as gypsies, were required to wear a yellow badge, similar to the yellow Star of David that Jews were forced to wear. This badge served to identify and discriminate against them, leading to widespread persecution and violence. Many Romani were imprisoned, enslaved, or killed during the Holocaust, as they were targeted by the Nazi regime for their ethnicity.
