It’s because of them the stigma around red hair originated
>In European culture, prior to the 20th century, red hair was commonly identified as the distinguishing negative Jewish trait.[8][9] This stereotype probably originated because red hair is a recessive trait that tends to find higher expression in highly endogamous populations, such as in Jewish communities where Jews were forbidden to marry outsiders.[9] Red hair was especially closely linked with Judas Iscariot, who was commonly shown with red hair to identify him as Jewish.[9][10] During the Spanish Inquisition, all those with red hair were identified as Jewish.[8][9] In Italy, red hair was associated with Italian Jews.[10] Writers from Shakespeare to Dickens would identify Jewish characters by giving them red hair.
