In 790 Idris I marched eastward to Tlemcen. The people of Tlemcen opened its gates for him and pledged allegiance to him, enabling him to seize the city without a fight.{{sfn|Mercier|1888|p=260}}<ref>{{cite book |editor1-last=Elfasi |editor1-first=M. |title=General History of Africa Volume 3 |date=1988 |publisher=Unesco |page=255 |isbn=978-92-3-101709-4 |url=https://books.google.com/books?id=tw0Q0tg0QLoC&pg=PA255}}</ref>
Following his seizure of Tlemcen, he directed his efforts towards the Rustamid capital of Tahert. He attempted an attack against Tahert, however he failed under its walls as a result of its strong defenders.{{sfn|Abu Nasr|1971|p=76}}{{sfn|Didier|1931|p=286}}{{sfn|Mercier|1888|p=260}}<ref>{{cite book |title=Bulletin |date=1913 |publisher=Société de géographie d'Alger et de l'Afrique du Nord |page=293 |url=https://books.google.com/books?id=dv8wAQAAMAAJ&q=%C3%A9chouer}}</ref> Following this failure, he returned to Walila and left a governor in Tlemcen to represent him.{{sfn|Mercier|1888|p=260}}
