Davis Cup was created in 1900 by Dwight Davis, a student at Harvard University who founded an annual competition between the US and Great Britain. The very first edition was held on August 8, 9 and 10, 1900, on the grass courts at Longwood Cricket Club in Boston. The Americans defeated the Brits 5-0. Over the years, the event expanded to include other nations and was eventually renamed the World Cup of Tennis.
Today, Davis Cup is the largest annual international team competition with over 130 nations competing.
