The Greek roots
Literally: “rule of five”
The story of the word
Justinian's legislation shaped the church version: Rome, Constantinople, Alexandria, Antioch and Jerusalem, ranked in that order, with authority meant to be shared among them. The schism of 1054 broke it and nothing has replaced it. Historians reuse the word for the five great powers who ran nineteenth-century Europe after Vienna. Archē carried both beginning and rule, which is how archaic and monarchy come to share a syllable.
