Czar Nicholas-very interesting BIO

[Vetus Ordo]

I haven't but it seems interesting.

Was Alexander II the Tsar rumored to have converted to Catholicism late in life?

He was orthodox but I cannot see our Lord despising a martry for the Faith.....but God is Judge.
and hisfamily's- murderers are in the deepest pits of hell (assuming of course  no repentance for their satanic deed) BTW they were all Marxist Russian Jews..predecessors of todays eratz Isreal

The martyred Tsar was Nicholas II, not Alexander II.

Anyway, Vivace has already provided the information I was looking for. It was Paul I the one rumored to have converted to Catholicism.
