People have speculated about that for a long time. Relevant factors seem to be the decay of the Roman military discrediting Christianity’s major rival, Mithraism, lack of vitality in the pagan faiths such as diminished oracular activity discrediting them (‘the silence of the oracles’), and good political luck.
