I suppose you could say that the American Civil War had shades of this as well - the abolitionist movement was very religious, that men like John Brown, William Garrison, John Rankin, and Elijah Lovejoy were its most ardent supporters shouldn’t be surprising. Conversely I have read that Southern universities was a hub of secularist thought in the US with regards to biology and the like, and that many Southerners outright denied things like a common ancestry for all races. Whatever religiosity that the South had was a result of its own traditions, whereas many Christians in the North viewed the war as a religious crusade. But then begs the question of how much of Northern religiosity comes from its Puritan heritage? It’s interesting to think about. That the South had numerous Jews in their ranks, with Judah P. Benjamin being its Secretary of State, whereas Union Generals Grant and Butler were pretty anti-Semitic in their war time behavior is another interesting contrast (Butler going so far to say that the Jews are betraying America as they betrayed Jesus).
