The Boston tea party and African American activists have one similarity and that is both wanted freedom from their oppressors. African Americans wanted to be treated as equal to their white counterparts. People contributing to the Boston tea party wanted freedom from their king who treated them terribly. The difference however, is that African Americans were treated as less than whereas most participants in the Boston tea party would still be well off even if they didn’t participate in the throwing of tea.
Hope this helps Xx :)
