Sorry for bad english.
Our teacher throw this question for us to ponder over weekend, before next lecture. I read our course book and tried to search Wikipedia, but Im not 100% satisfied with the answers. I tought this place might have better answers
I m sorry that i have to ask, but did he/she really gave you such a broad task? The Portuguese established the first "real" worldwide empire, so probably start there, but roughly said:
technological advantage, shared knowledge, deception,surprise, brutality, occasionally a bit of "game of thrones" and "divide et impera" - depending on which kingdom and which colony we are talking about
