Bronze Age was an era in human history between Stone Age and Iron Age, when metallurgy, early states, long-distance trade and writing were invented. In the Middle East, it started about 3300 BC followed by the development of Sumerian city-states and Egyptian monarchy. In other parts of the world it started much later, for example about 1900 BC in England and 1600 BC in China.
Socially, the era was dominated by polytheistic religions and absolute power of kings and nobles claiming descent from the gods. Despite this oppressive character, some Bronze Age societies had impressive knowledge of medicine, astronomy and architecture. Some individuals were however unhappy with this society, like Abraham who started a new religion (Judaism) based on the idea of covenant with One God.
Bronze Age ended between 1200 BC and 600 BC when human beings learned how to use iron. Late Bronze Age collapse was an important watershed for the Eastern Mediterranean regions, resulting in end of many established societies, and birth of new ones such as the Kingdoms of Israel and Judah as well as Ancient Greece. In other places like Italy the transition was more peaceful and gradual.
