The Group of Eight (G8) was an intergovernmental political forum from 1997 to 2014, formed by incorporating Russia into the G7. The G8 became the G7 again after Russia was expelled in 2014 after the Russian annexation of Crimea.
The forum originated with a 1975 summit hosted by France that brought together representatives of six governments: France, Germany, Italy, Japan, the United Kingdom, and the United States, thus leading to the name Group of Six or G6. The summit came to be known as the Group of Seven in 1976 with the addition of Canada. The European Union (or predecessor institutions such as the European Economic Community) was represented at the G8 since the 1980s as a "nonenumerated" participant, but originally could not host or chair summits. Russia was added to the political forum from 1997, which the following year became known as the G8. In 2005, the UK government initiated the practice of inviting five leading emerging markets – Brazil, China, India, Mexico, and South Africa – to participate in the G8 meetings that came to be known as G8+5.
