European secularism grew from Christianity adapting to post-Reformation religious compromise.

Evidence

Indeed, one can make an argument that ‘secular’ society as we now see it in Europe is the result of the adaptation of Christianity to the model of secularism that arose as a compromise formation out of the wars of religion following the Reformation. The integration of the Jews into Enlightenment Europe, as Adam Sutcliffe has shown in his Judaism and Enlightenment, was integration into Christian Europe (with Christianity having different textures in England than in Holland than in Bavaria, and so on). — James Renton, Ben Gidley (eds.), Antisemitism and Islamophobia in Europe, 878
