It was a prolific civilization that had a great influence over the political system and the cultural life of these regions. The Ancient Greece was the place where democracy and philosophy were invented, and their thought and aesthetics would have a great influence over different civilizations throughout millennia. The Romans in particular took Greek elements from their mythology, architecture, philosophy, and politics, among other aspects, and used them to build the foundations of the Roman Empire, that would take Greek ideals to new frontiers. It was labeled as a classical civilization by Renaissance Historians that were inspired by the ancient Greek and Ancient Roman cultures and tended to idealize them.
