This chapter explores the religious and political influences that shaped Abdullah Quilliam’s Muslim missionary activities, philanthropic work and scholarly writings in an attempt to shed light on his particular political convictions as manifest through his unique religiopolitical endeavors. It focuses especially on Quilliam’s Methodist upbringing in Liverpool and his support of the working classes. It argues that Quilliam’s religious and political activism, although primarily inspired by his conversion to Islam, was also shaped and influenced by the then newly emerging proletariat, revolutionary socialism. Quilliam’s continued commitment to the burgeoning working-class trades union movement, both as a leading member representative and legal advisor, coupled with his reputation as the "poor man’s lawyer" because of his frequent fee-free representations for the impoverished, demonstrates his empathetic proximity to working-class struggles.
