Most social reformers formed associations *cos  they believed that a group would attract more attention from people rather than the individuals...and also by forming associations they get chance to share their own thoughts with others and they could get so many ideas about we say unity is strength ...these associations helped them to carry out the reforms in a more effective way.....
