At 17:40, he says "They killed tens of thousands of Babis in Persia in the early 1800's in the most horrifying ways." In fact, Denis MacEoin concludes](https://bahai-library.com/uhj_mazandarani_number_martyrs) that the "number of early Babi/Bahá'í martyrs was not 20,000, as 'Abdu'l-Bahá and Shoghi Effendi mentioned numerous times, but 2,000 to 3,000 (e.g. MacEoin, "A Note on the Numbers of Babi and Bahá'í Martyrs in Iran," in Bahá'í Studies Bulletin, 2.2, Sept. 1983, and "From Babism to Bahá'ísm: Problems of Militancy, Conflation, and Quietism in the Construction of a Religion," in Religion, 13, July 1983)." 

At 18:00, he omits that Bahaullah, as one of the leaders of the Babi movement, was imprisoned after some Babis unsuccessfully attempted to assassinate the Shah of Iran. 

At 20:15, Bahaullah was exiled and not executed due to heavy pressure from the Russian consul, who had some political authority over the Iranian state at the time. In fact, Bahaullah was escorted with an entourage of Russian horseman to his exile in Baghdad, which was part of the Ottoman Empire at the time. Bahaullah left Baghdad without telling his family to study with Sufi sheikhs in Kurdistan. 

At 22:00, the Bab said the next manifestation would come in 1000 years, not a short time. 

At 22:20, Bahaullah's followers were engaged in internecine fighting with the followers of Subh-i-Azal, which is why the Ottoman authorities moved him to Acre, Palestine. 

At 26:18, he correctly quotes Bahaullah as saying, "That diversity in religion should cease." 

At 47:30, he says "There are two choices about Bahaullah." No, in fact, there are many more conclusions that one can more objectively reach than those two.
