Al Mu’tamid’s reign lasted from 870 to 892. The Abbasid Caliphate was reborn during these decades, midwifed by the caliph’s brother Talha, better known in history by his title al Muwaffaq. The new Abbasid state understood its limits and adopted a pragmatic but uncompromising approach towards rebuilding its power. It developed formidable armies to fight off the many existential threats that faced it, then used this military edge to force its neighbors into relative submission.
