Haven't you seen the in-game slides? They state the Brotherhood warred with the NCR for control of advanced tech. The NCR attacked a Brotherhood-held Helios then all hell broke lose, the BoS lost and had to retreat. The Legion wants to decimate the NCR and conquer New Vegas.
Not trying to come off as a jerk, but this stuff is all laid out in the game.
