Encyclopedia Iranica says that "Azeri Turks were founders of Safavid Dynasty" per the reference provided on the Safavid Dynasty page. This is a reference based on Richard Frye, who is prominent Iranologist. Kurdish origins of Sheykh Safi are also mentioned. But there is no doubt that Safavids at the time of their rise to power were Turkic-speaking by any serious historian. This is also not denied by any average Iranian, more or less familiar with history. So stop making reverts without consulting the Talk page. We are not "ultra-nationalist Turks", but we will resist any attempt to deny or steel our origin against factual information.
