What achievements and lessons did the Assyrian empire leave us with?

1. Mass use of cavalry in war, before the Assyrians, no one was involved in this, except that they used chariots.

2. The use of iron for the manufacture of tools and weapons for the army, before the Assyrians used mainly copper and bronze.

3. The Assyrians founded the first library known in the Ancient World, it was located in their capital Nineveh, and cuneiform tablets made of clay and papyri from Egypt, which was a vassal of the Assyrians, replenished its collection.
