The last Ice Age was the era of the big grazing animals. Mammoths, musk oxen and reindeers roamed the vast landscapes. In the middle of this cold period, modern man migrated from the African savannahs to Germany. As hunters and collectors, their lives were determined by the migratory patterns of the herds. In 5,500 BC, farming started with the so-called Neolithic revolution. After conquering parts of the land, the Romans began building supply systems and networks of roads. Their camps later developed into towns such as Cologne, Mainz and Coblenz.
