Shaykhi school of thought responsible for the formation of the Babi and Baha'i movements

It will also be observed that there are implications regarding Aḥsāʾı’s intention in bringing an alternative to the mainstream (Usụlısm ), proven by a number of facts, including his efforts to redefine ijtihād, as well as the emphasis on his recurring dreams of the imāms. And last but not least, although Shaykhısm̄ is an autonomous school of thought and should not be evaluated by later events, it was the Shaykhı conceptualization of notions such as leadership, occultation, eschatology, the future return, and the occult sciences that rendered the formation of the subsequent movements of Bābısm̄ and Bahāʾısm̄.
