The historical method includes classifying data, analysis of data and finally reporting on data. The method itself is slightly different to the scientific method but in essence wishes to do the same thing as the scientific method - elucidate the secrets of the world and gain new knowledge.
Maybe for power? The Nazis might have known that if you wanted to break a family apart, you could take the kids away from the parents. Since the parents dont want their kid harmed, or worse, they probably would do almost anything to save them. This might result in them fighting for the Nazis or supporting them, in order to save their young. With the parents depressed and searching for their young, the Nazis might have a smooth and easy takeover.
God bless
The British victory in the French and Indian War had a great impact on the British Empire. Firstly, it meant a great expansion of British territorial claims in the New World. But the cost of the war had greatly enlarged Britain's debt. Moreover, the war generated substantial resentment towards the colonists among English leaders, who were not satisfied with the financial and military help they had received from the colonists during the war. All these factors combined to persuade many English leaders that the colonies needed a major reorganization and that the central authority should be in London. The English leaders set in motion plans to give London more control over the government of the colonies and these plans were eventually a big part of the colonial resentment towards British imperial policies that led to the American Revolution.
