Western scientists who write and are interest in Bulgaria's history are very few. Therefore, the discovery of the new manuscript entitled "The Importance of Bulgaria on the Partition of Eastern Christianity from the West" is an event which lists its author, German Hans-Dieter Döpmann, besides the names of the few foreign scientists who have once written for Bulgaria - Konstantin Irecek, Steven Runciman and Francis Dvornik.
This work of the German scientist was accidentally discovered at the Leipzig Library in 1992 by Radomir Collolov - a specialist in the field of Germanism. He took the work with him and this work has remained in his home until 2016.
The story told by Döpmann is from the period 860-880, while the heroes are three popes, two patriarchs from Constantinople and the Bulgarian prince Boris I. Doppmann attends Pope Nikolay I's (858-867) evidence to
attract Bulgaria into Catholicism and his fight with the Byzantine Patriarch of Fot, where the Pope was the losing side.
Thus, Bulgaria has continued its development as an Orthodox Christian state.
