Assyria
Assyria was a major ancient Mesopotamian civilization that existed from the 21st to the 7th century BCE which conquered and administered most of West Asia from the Assyrian heartland in Upper Mesopotamia. Assyria is called the first true military superpower in human history, and pioneered major inventions and advances in the first libraries and large-scale preservation and accumulation of knowledge, as well as in statecraft, centralised government, bureaucracy, warfare, military organisation, propaganda, art, and architecture.
