Gold Rush Season 9 Episode 1 | Declaration of Independence

A gold rush is a new discovery of gold—sometimes accompanied by other precious metals and rare-earth minerals—that brings an onrush of miners seeking their fortune. Major gold rushes took place in the 19th century in Australia, New Zealand, Brazil, Canada, South Africa and the United States, while smaller gold rushes took place elsewhere.

In the 19th century the wealth that resulted was distributed widely because of reduced migration costs and low barriers to entry. While gold mining itself proved unprofitable for most diggers and mine-owners, some people made large fortunes, and merchants and transportation facilities made large profits. The resulting increase in the world's gold supply stimulated global trade and investment. Historians have written extensively about the migration, trade, colonization and environmental history associated with gold rushes
