However, the Elder council had little idea of just how much of a following Julian had.
The Brotherhood of Steel found Julian's 'blatant imperialism', unsettling and ordered that he be exiled. Julian was exiled for holding that the Brotherhood of Steel's mission would be better served if they tried to conquer various settlements, eventually taking over the whole nation of America, and make their will the law of the wasteland. The Idaho Brotherhood was created when a Paladin by the name of Julian Rotter was exiled from the California Brotherhood in 2111.
