ROSA has been initiated by women in the Socialist Party, with the aim of promoting and organising events, actions and campaigning activity on the issues mentioned, open to anyone who supports its message to participate in. 
It’s named after Rosa Parks, the inspirational black campaigner who famously refused to give up her seat for a white passenger, sparking the Montgomery bus boycott of the Civil Rights Movement And also after Rosa Luxemburg, exceptional and leading socialist theoretician and activist of the early 20th century, killed for her revolutionary politics in 1919.
