Who invented bronze breastplates for war?

The invention of bronze breastplates for war cannot be attributed to a single individual, as they emerged gradually across various ancient civilizations, particularly during the Bronze Age (around 3300-1200 BCE). Cultures such as the Sumerians, Egyptians, and later the Greeks and Romans developed and refined the use of bronze for armor. The advancements were driven by the need for better protection in warfare, facilitated by innovations in Metallurgy and craftsmanship over time.
