When did European bronzes begin to develop?

The earliest bronze age in the world was in the two river basins and Egypt, which began in 3000 BC.

China's bronze age began in the Xia, Shang, Western Zhou, Spring and Autumn Period and Warring States Period more than 2500 BC.

The Tanum rock paintings in the Bronze Age in northern Buhus can be traced back to BC 1800, which also proves the development time of the Bronze Age in Europe.
