 Descriptions of the extent of the amirate by medieval Muslim historians vary; one source states that it controlled only al-Khidhrimah and its outskirts, while another claims that it ruled over a territory that extended as far north as Qurran.The early rule of the Banu 'l-Ukhaidhir was characterized by a sustained economic depression.Thousands of people are recorded as having emigrated from al-Yamamah to various provinces of the caliphate in order to escape the turmoil.
