What was their purpose and were they successful?

To provide a precise answer, I would need more context about who "they" refers to and what purpose you are asking about. However, if "they" refers to a specific group or initiative, their purpose generally involves achieving specific goals or objectives, such as social change, innovation, or improvement in a certain area. Success can be measured by the outcomes they achieved compared to their original goals. If you provide more details, I can give a more tailored response.
