Well, one of those events wasn't a war, unless Martin Luther sacked some principality I'm unaware of after he finished posting his 95 Theses? There are plenty of other notable events that weren't military events.
Martin Luther and his 95 theses are an excellent example of how military events are sometimes completely dwarfed in importance by non-military events. Quite often, wars are just the waves on the surface of the sea of history.
If newspapers had existed in 1521, and we could read them, they would be full of news about the latest Italian War between France and the Empire. The news that a German theologian had been condemned for heresy at the Diet of Worms would have been confined to the back pages--and even then, it would have seemed important mostly because it was preoccupying the Emperor, when he should have been devoting his full attention to the war with France.
But, who today has heard of the Italian Wars? Which is not to say that these conflicts didn't have important consequences--especially for Italy. Just that they have long since been eclipsed in popular memory by the Protestant Reformation.
I think there are two reasons why war looms so large in history, even today, compared to other subjects.
First, because whatever else it is, war can be very dramatic. Conflict is the essence of drama, and war is conflict in its most direct and physical form.
Second, because wars are the business of governments, and until relatively recently, history has been government-centric. Even today, government archives are still one of the most important sites for historical research.
On the one hand, people--especially men--just enjoy reading about war. Economic history, by contrast, puts most people to sleep--despite its obvious importance.
On the other hand, since history is the study of the written records of the past, its content is determined by what has been documented, and what hasn't.
If you go, for example, to the National Archives of the United Kingdom, you'll find that one of its most extensive document collections is the papers of the War Office. And one of the chief reasons why members of the public go to the NA is to search through the service records of British soldiers and sailors of the Great War, looking for their ancestors.
