Zoos have a long history that can be traced back to ancient civilizations. In ancient Egypt, pharaohs showcased their wealth and power by collecting and displaying exotic animals from conquered lands. These collections, known as menageries, consisted of a variety of animals such as lions, elephants, and giraffes. The animals were often seen as symbols of the pharaoh’s dominance over nature and were kept in enclosed spaces within palace complexes. These early menageries served as the precursors to modern zoos, laying the foundation for the preservation and exhibition of wildlife.

The Tiergarten Schönbrunn, founded in 1752, is widely regarded as the first modern zoo in the world.
