ABSTRACT
Accounts of how the Church organization started in Central and Eastern Europe and how it grew until the 12th century are incomplete and highly conjectural. The scarcity of sources, which sometimes contradict each other, leads to hypotheses based only partially on the sources. Few of them are therefore verifiable, given the considerable differences between historians’ opinions. This is the reason for which the development of the Church organization presented in this chapter is a compromise between a concise historical outline and a historiographic survey.
