The Bronze Age of Comic Books is an informal name for a period in the history of mainstream American Comic books usually said to run from 1970 to 1985. It follows the Silver Age of Comic Books.
The Bronze Age retained many of the conventions of the Silver Age, with traditional superhero titles remaining the mainstay of the industry. However, a return of darker plot elements and more socially relevant storylines (akin to those found in the Golden Age of Comic Books featuring real-world issues, such as drug use, alcoholism, and environmental pollution began to flourish during the period, prefiguring the later Modern Age of Comic Books.
