 Starting in the twentieth century, in addition to repression aimed at individual Baháʼís, centrally directed campaigns that targeted the entire Baháʼí community and its institutions were initiated.In one case in Yazd in 1903 more than 100 Baháʼís were killed.Baháʼí schools, such as the Tarbiyat boys' and girls' schools in Tehran, were closed in the 1930s and 1940s, Baháʼí marriages were not recognized and Baháʼí texts were censored.
