Context: The most important competition in rugby union is the Rugby World Cup, a men's tournament that has taken place every four years since the inaugural event in 1987. South Africa are the reigning champions, having defeated England in the final of the 2019 Rugby World Cup in Yokohama. New Zealand and South Africa have each won the title three times (New Zealand: 1987, 2011, 2015; South Africa: 1995, 2007, 2019), Australia have won twice (1991 and 1999), and England once (2003). England is the only team from the Northern Hemisphere to have won the Rugby World Cup.
