You mean : Ultramontane, Archimandrite.
But the Sacred Heart was a much older devotion, going back to Gertrude, and then Margaret Mary Alacoque [+1674].
So it was not a 19th century phenomenon. Just was revived, especially at the fin de siecle by such religious, to use the Catholic term, as Sister Mary of the Divine Heart [+1899], the Superior of the Good Shepherd Convent in all places, the second city of Portugal, Oporto.
It's not too far from there to Fatima. This nun was able to persuade the Pope at that era of the need to consecrate the entire human race to the Sacred Heart. Pope Leo XIII ignored her request at first, but the next year, 1899, after he was cured from an unspecified illness, he was impressed enough to actually carry through with this dedication. I believe the consecration was done together with all the Bishops of the Catholic Church, a very rare occurrence.
This Pope attributed his quick cure to Jesus and felt that the nun's exhortation for him to consecrate the entire race of humans to the Sacred Heart was really from the Savior. He protested "Why not just "all Catholics"?" Sister Mary, a German Countess by birth who had given up all to join a very difficult order of nuns and struggled to keep her house in Porto afloat, gave a reply that it might make the non-believers feel drawn to convert to Christianity.
However Sister Mary Droste zu Vischering [ her family name, among the best and oldest of Westphalian nobility ] did not live to see the success of her campaign : she died a day before this consecration took place.
This entire episode and the nun herself are almost unknown today. Completely forgotten and certainly not mentioned in any major - or minor - history of Catholic mystics. In fact, seeing the paucity of written material on this visionary, it seems the entire incident was suppressed by Catholic Church authorities. Her name was "of the Divine Heart" because another sister already was "of the Sacred Heart", by the way.
I am mentioning this to add a rare account to give a more accurate picture of the Sacred Heart devotions in the 1800s.
