When Italy were admitted into Europe’s premier men’s international rugby union tournament in 2000, the Six Nations was born.
It was an historic moment for the annual 15-a-side competition, with previous iterations of the tournament dating back to 1883.
Before Italy joined, the Five Nations was contested by England, France, Wales, Ireland and Scotland.
England have been the most successful Six Nations team with seven titles, but holders France and Wales have the most Grand Slams - when a team wins all five of their fixtures - with four apiece.
England and Ireland have both completed two Grand Slams.
Scotland claimed the last Five Nations title in 1999, but their best Six Nations finish to date is third which they have achieved on three occasions.
It’s been tough going for Italy so far who, despite having beaten every team other than England, have only twice finished in the top four.
They will hope to break that trend when the 2023 Six Nations Championship begins on 4 February.
Among the array of stars on show, keep an eye out for Scottish winger Ruaridh McConnochie, who won silver with Great Britain at the Rio 2016 Olympics (below).
