Early and Byzantine Orthodoxy

The historical arc of the Eastern Orthodox Church from the apostolic age through the Byzantine millennium to the end of Ottoman rule. This subsection treats these centuries as history — the institutions, events, and persons — while the doctrine defined in them (the councils, the Filioque) is housed in its proper dogmatic sections and cross-linked throughout.

Tradition: Pan-Orthodox

These three files trace one continuous story across roughly eighteen centuries: the undivided Church and the slow East-West drift that set up the schism; the Church inside the Byzantine Empire, with a gradualist account of 1054 following the scholarly consensus (Runciman, Kolbaba) rather than the myth of an instant split; and the four centuries of Ottoman captivity down to the autocephaly wave of Greek independence.

Content is born verified per METHODOLOGY.md: contested figures are given as ranges or dated, sourced claims, and disputed questions name the positions.
