The Tahirids were a local clan based in Rada'a. While they were not as impressive as their predecessors, they were still keen builders. They built schools, mosques, and irrigation channels, as well as water cisterns and bridges in Zabid, Aden, Rada'a, and Juban. Their best-known monument is the Amiriya Madrasa in Rada' District, which was built in 1504.
