As part of the seminar series Historia Ecclesiae et Religionis (organised by the Centre for the Study of the History of Religion and the Church at the Russian Academy of Science), Irina Paert, one of the founders of balticorthodoxy.com, has given an extremely compelling account (in Russian) of the Riga Church Council of 1905, one of the most significant moments in the Orthodox ecclesiastical reform movement during the imperial period. The lecture, along with others in the same series, can be found on youtube at https://www.youtube.com/watch?v=HTVOKrnRBHs.
