of Nader Afshar () as Shah. The Turkish academic, Mustafa Aydın (born 1967), also wrote the above narrative in the İslâm Ansiklopedisi. Mammadova didn't think that Seyyed Abbas could have lived that long. If Seyyed Abbas died in 1749 (according to The Chronicle, his reign lasted 20 years), then he should have come to power in 1729. At that time, Nader was not the Shah of Persia. On the other hand, Russian archival documents show that Mir Abbas Beg was captured and beheaded by the Ottomans during the 1726 invasion. Asadov wrote that Nader Shah ordered Seyyed Abbas to come to power in Talysh. However, he does not say where he got it from. This would not be possible. Because, first of all, the archival documents say that he had killed. The second is that in Saeid-Ali's book when Nader proclaimed himself as Shah, he wrote that Mir Abbas was no longer alive. The decree for Seyyed Abbas was issued in 1654 and seems that Asadov confused the "Seyyed Abbas" with the "Mir Abbas". Seyyed Abbas could not attend the Mughan kurultai or die in 1747. The Chronicle stated that Seyyed Abbas had only one sister. However, Saeid-Ali wrote that Qara Khan took control of Talysh in a short time and always tried to extinguish it when enmity broke out between his cousins and his sons. Thus, they were brothers of Mir Abbas, not Seyyed Abbas. The contradictions between The Chronicle and The Jewel Book of Lankaran are obvious and far from reality. Mammadova believed that it would be right to prefer Saeid-Ali, because he approached the events from Mirza Ahmad's historical point of view, used the historical sources of his time and in some cases expressed a critical attitude. The author indicates the exact date of the 1654 decree, thus it can be assumed that he saw the decree. The Chronicle attributed this event to the period of Nader's rule and described that he turned from a poor man to the level of Lankaran's ruler. According to Mammadova, This is not convincing because it is incompatible with historical events. Seyyed Abbas is not mentioned in the works of Russian and foreign travellers who visited these areas, only Musa Khan of Astara is mentioned a lot. It should be concluded that there were two people with the name of "Abbas". The first was Seyyed Abbas, who founded the dynasty of
