Edward Browne considered the Azalis more reliable than the Baha'is

He thus considered the Azalīs more reliable than the Bahais in putting him in touch with the Babi past and regretted the rivalry between the two groups. He seems early on to have taken the Azalī side in the struggle; when Iranian Bahais reproached him for inclining to Azal, he did not deny it and blamed Bahai violence toward Azalīs (1893, repr. 1926, pp. 578-79). In his 1889 papers for the Journal of the Royal Asiatic Society he set out for the first time in English a detailed account of the evolution of Babism and the rise of Bahaism after 1850. He entered into frequent correspondence with Azal and his followers and in the spring of 1890 voyaged to Cyprus, where he spent two weeks with Azal, then to ʿAkkā (Acre), where he spent a week with the Bahais.
