The Gardens of Babilon were amazing engineer constructions that King Nebuchadnezzar (605 BC) built for his homesick wife to resemble the gardens of her hometown. He used slaves to construct them. They consisted of terraces raised one above another resting upon hollow pillars filled with earth to allow trees of the largest size to flourish. The technology used to build the Gardens of Babilon included water irrigation system from Euphrates River which then had to be lifted far up so it could flow down through the terraces, watering each level of plants. This was a big engineering task because it had to include a chain pump with two large wheels, one above the other; on one chain buckets were hung and as the wheel was turned, the buckets dipped into the pool and picked up water. The chain then lifted them to the upper wheel, where the buckets were tipped.

In order to keep the fragile balance of power in the period before the World War I, countries entered alliances with one another. So for example, France, Russia and the Great Britain were in one alliance and the Germans and Austrians in another. If one country entered a war the other were obliged to go to their aid. That is how the World War I escalated.
