England's dominance in the Women's Six Nations is unmatched, with 16 titles since the competition began in 2002. The Red Roses have won eight consecutive years, including last year's Rugby World Cup on home soil. France follows with six titles, while Ireland holds two, from 2013 and 2015.

The tournament evolved from the Home Nations in 1996 to the Five Nations in 1999 and the Six Nations in 2002, with Spain and Italy joining at different stages. Spain competed in the first five years of the Six Nations and the final two Five Nations tournaments before Italy replaced them in 2007. These historical milestones highlight the competition's growth and the fierce rivalries shaping its legacy.
