I don’t have any figures on the extend of Islam aggression and the deaths caused by that fanaticism — however, I can speak to Henry VIII and his genocide with the Roman Catholic Church in England. It is thought that approx. 100,000 people from a population of 2 million were executed. Even if you play with the numbers (say downgrade the number death to 70,000 - 80,000) and up the population, (say 2.5 million), you’re still taking about a significant section of people. I believe Elizabeth I was worse.
Here is the relevant excerpt from Laux's Church History: "The total number of men and women, priests, monks, etc., who suffered death in England for the Catholic faith from 1535 to 1681 is over six hundred, several hundred of whom have been beatified." (p 454) Of course, Fr. John Laux's book is the Roman version of the story so it doesn't tell you that Bloody Mary, Henry's daughter who adhered to the Church of Rome, killed comparable numbers of Christians, usually burning them alive.
200,000? Seriously? Wow. The worst internecine slaughter of Christians during that period occurred in France, during the St. Bartholomew's Day Massacre: The number of Huguenot's murdered is estimated to be between 5,000 and 30,000. Unlike the English persecutions, which were confined to specific cases, that particular bit of Roman treachery was a deliberate decapitation strike against the French Reformers, whose leaders had gathered to honor a royal wedding.
