Hoe is het neef-nicht taboe de wereld in geholpen?
Zo: Cousin marriage in Europe was common. Travel was difficult. Neighbor married Neighbor through out generations. Political alliances were secured by the marriage of both parties families. Wealth, and the power it provided, was invested in a few people. The rulers of the time were concerned that the concentration of wealth in the hands of few would lead to anarchy. To break up these vested families and redistribute the lands and monies of these families they prohibited cousin marriages. At the same time they exempted the Royal Family from that same prohibition.
