Final answer:
No, the first civilizations did not outfit armies entirely with iron weapons. While iron weapons were used in ancient civilizations, they were not the primary weapons of choice in the early stages of the Iron Age. Bronze weapons were still more commonly used.
Step-by-step explanation:
No, the first civilizations did not outfit armies entirely with iron weapons. While iron weapons were used in ancient civilizations, they were not the primary weapons of choice in the early stages of the Iron Age. Bronze weapons were still more commonly used, as iron was more difficult to work with and took a long time to produce iron weapons that were hard enough to endure battle conditions.
The Assyrians, for example, were the most effective military force of the ancient world and their large armies were outfitted with well-made iron weapons. They were the first major kingdom to manufacture iron weapons in large numbers. However, other civilizations, like the later Egyptian kingdoms, did not use large amounts of iron tools until much later, even though iron use was becoming increasingly common.
In conclusion, while iron weapons were used in ancient civilizations, they were not the primary weapons used by the first civilizations.
