I promise I will reserve my judgement on "conversion of non-Andrastians by the sword" until we know for sure what happened in the Dales and what consequences the Rivaini Chantry faced from their superiors after the purges. As for "conversion of No True Andrastians", I suppose Tevinter will have a different opinion.
What would those exact circumstances of the aftermath matter? The Chantry didn't start those wars, which would be a key aspect of-
'The Chantry has never initiated a religious war against non-Andrastians for the purpose of conversion.'
By the way, finally managed to find a timeline about Tevinter's turn to magocracy (remember what we talked about if it was quickly or not?). Apart from WoT, the clue was the codex entry on the Imperial Chantry.
-3:87: The Divine asks the Imperial Chantry to conform to the Orlesian version of the Chant. Tevinter refuses. Joyous II declares the entire Tevinter clergy heretics. The Imperial Chantry answers by electing its own Divine, magister Valhail I.
-3:99. The White Divine dies. In Tevinter there's celebration. The new White Divine calls the new age "Black" to remind everyone of the false Divine.
-4.40: Start of the first of four Exalted Marches against Tevinter.
-5:10: The last Exalted March against Tevinter ends in retreat for Orlais.
-6:32-7:84: Qunari Wars.
-7:34: The election of Nomaran as Archon directly from the ranks of the enchanters marks the beginning of the Circle ruling Tevinter politics again. He dispenses the old rules forbidding mages from taking part in politics.
-8:11: By this year, the mages rule openly in Tevinter again. The Grand Enchanter always holds the title of Divine.
Good find. I can't PM it to myself for future reference, so could I ask you to do so? (Also, do you have the dates of the post-Andraste Tevinter incursions?)
Though I will point out, for your benefit for future arguments, there was over a fifty year schism between the Black Divine's breakaway and the start of the Exalted Marches. A sudden, reactionary mobilization to religious schism it was not, unless you're willing to overlook a generation or two of separation. If the Chantry was willing to wait nearly half of the age that bears its name before attacking, that's not a particularly argument of the primary motivations being to squash religious dissent.
Lambert was right about the timeline.
Not as much as you might think- from that timeline alone you can already get a strong implication of covert (rather than overt) mage political influence well before the doing away of the pretenses in 7:34. You could even peg Magister influence as far back as nearly four centuries before the present, at the religious schism, though obviously the magister power networks would have to been restructured well before then to actually make such an attempt a success.
