The "bloody parcels" were received by the Ukrainian embassies in Hungary, the Netherlands, Poland, Croatia and Italy, and by consulates in Naples, Italy; Krakow, Poland; and the Czech city of Brno, according to Oleg Nikolenko, a spokesman at Ukraine's foreign ministry.
Beginning in 1520, right after Martin Luther's Reformation, bloody religious wars began that kept recurring almost yearly for over a century. The Reformation's rapid spread drew battle lines accross Europe as Catholic armies were fielded to crush the Protestants into submission, engulfing the continent in intermittent war from the 1520s to the 1640s. But what was the real cause of these recurring wars? In other words, "Why not live and let live?"
So on one side, you have people fighting for some sort of freedom, and on the other, people very much happy with the current state of things. The catholic rulers were promised reward in return for their contributions to the wars (as well as continued support in the "divine" department), while the various "reformed" wanted to break that power block apart (some actively, some defensively - my country's Hussites were mostly said to be concerned with keeping the Bohemian crown lands sovereign and letting everyone else do whatever; they got a Crusade for their troubles). And worse, the countries rarely switched "en masse" - so you might have half-catholic, half-reformed people fighting each other, which has historically often resulted in very bloody wars. The catholic church never head a threat of this scope - if they wanted to keep any power at all, they had to do everything they could to hold on. They saw the reformation as a challenge to their rule - which was true, of course, to various extents. Both the worldly and the divine rulers were just humans, despite what the church claimed - and they didn't want to lose any power.
This is not the only pope implied in this business, he's not gonna be the one who start the building, not the one who finished, as they have a tendency to change with some frecuency in this times, but have in mind than at this time, some time before and several times after all the popes are gonna be part of some of the powerfull familys of the European boot, the duration of this is the same than the duration of the pontifician states (751 - 1870), which was the reason why the powerfull familys in europe are gonna be willing and trying to take power over it when they can.
One way I could try and explain: If you are not especially interested in european history and were born rather recently you would probably not even think of some german monk when you hear the name. It shows that information control can create a shift in narrative which by it's nature is something that limits the thoughts we are able to think.
In Spain, the "bloody packages" was found with a spate of letter bombs, including one that injured a staffer at the Ukrainian Embassy in Madrid. This incident has raised suspicion about links to Russia while prompting Kyiv to ask for increased security at its overseas offices, The Washington Post reported.
