The Moscow Mule is a cocktail made with vodka, ginger beer, and lime juice, served in a copper mug. It is believed to have been invented in 1941 by John G. Martin, an American businessman who was trying to sell Smirnoff vodka in the United States. Martin was having trouble selling vodka because Americans were not used to the taste of it. He came up with the idea of making a cocktail that would highlight the vodka's smooth flavor and ginger beer's refreshing taste.

Martin teamed up with Jack Morgan, the owner of the Cock 'n' Bull British pub in Los Angeles, to create the Moscow Mule. Morgan had a surplus of copper mugs that he was trying to sell. Martin and Morgan decided to serve the Moscow Mule in the copper mugs because they believed that the copper would help to keep the drink cold and enhance its flavor.

The Moscow Mule was an instant hit and quickly became one of the most popular cocktails in the United States. It is still a popular drink today and is often served in copper mugs to commemorate its history.
