In 297, actions against Manichaeans and a renewed army sacrifice test signaled rising religious control before the broader Christian persecution. Altars smoked in Sirmium; orders from Nicomedia pressed discipline into belief. The regime rehearsed compulsion before the main act.

What Happened

The Tetrarchy’s ideology bound imperial order to divine favor. In 297, two policy strands tightened: measures against Manichaeans—seen as a Persian‑tainted, subversive sect—and a renewed insistence that soldiers prove loyalty by sacrifice. Both moves previewed a coercive turn that would widen in 303 [16][2].

In army camps from Sirmium to Antioch, the test was straightforward: take incense to the altar, pour libations, and show your oath ran through the gods the emperors invoked. The sound was ritual—the murmur of prayers, the crackle of coals. In administrative centers, officials sharpened edicts against Manichaean teachers and texts, part belief policing, part geopolitical suspicion in a year when Galerius faced Persia [16].

These were not yet the sweeping decrees that would order church doors torn down, but they announced a principle: uniformity would be demanded where obedience mattered most—among soldiers and in domains the state considered ideologically dangerous. Eusebius, writing later of 303, would recall the cadence of persecution in Palestine and Egypt; in 297 we hear the warm‑up bars [2][16].

From Nicomedia, Diocletian’s chancery stitched belief to loyalty on paper. In frontier cities like Thessalonica and Alexandria, soldiers and civilians heard the message in person. The Tetrarchy’s confidence in shaping conduct matched its confidence in shaping maps and prices.

Why This Matters

These measures defined the state’s willingness to bind discipline to ritual. They also linked religion and security, casting Manichaeans as suspect in a year of Persian conflict and tightening the army’s ideological cohesion [16].

Within the ideology, law, and religion theme, 297 foreshadows the 303 edicts: selective compulsion in the ranks and against a targeted sect grows into general persecution of Christians. The apparatus—the proclamations, the tests, the punishments—was rehearsed [2][16].

In the wider narrative, the same administrative confidence that wrote the Prices Edict turned toward belief. By 311, as the political system frayed, Galerius would concede that compulsion had failed and permit assemblies under conditions of order [3][4].
