How is alliance system and militarism a cause of world war 1? (not the assassination of archduke )

It was because of the fact that European countries were allied to each other, that drew them into the conflict.

Militarism, or the building up of a nation's military, was done because Europe was nervous. Serbia built up it's military, which made Austria-Hungary nervous, so they built up their military, which made Russia nervous, so...and so on.

when people started to question traditional christian beliefs, they became criminals in the eyes of the church: they were accused of heresy and then, executed. the church held unbelievable power and anyone who tried to defy it or its beliefs, was demonized and persecuted.

mark brainliest and have a stunning day!
