Since 2009, member unions identified Integrity, Passion, Solidarity, Discipline and Respect as the defining characteristics of rugby. These are now collectively known as the World Rugby Core Values and are incorporated within the World Rugby Playing Charter, a document that aims to ensure that rugby maintains its unique character both on and off the field of play. The core values enable participants immediately to understand the character of the game and what makes it distinctive as a sport, which is played by people of all shapes and sizes. The World Rugby Playing Charter is incorporated within the World Rugby Laws of the Game and can be downloaded from worldrugby.org/laws in a variety of languages.
