It seems the thing with Controling other Houses was in the Great War...but considering the Experiments from the Naberius in relation to Superdevils (even it was said the Master of Kuroka was a branch of the Main Clan) it fits with the will of Lord Nebiros to research the Transcendent Devols (aka Superdevils) that he talks at the end of DxD Zero.

And Naberius is in Mythology under Control of Nebiros^^
