Based upon extensive archival research and bringing to life the words and actions of extraordinary individuals from the early 20th century, this book calls into question contemporary assumptions about the appreciation of diversity as a solely postcolonial phenomenon. It shows how Bahá'í, Muslim, and Jewish leaders prior to and during WWI found value in the existence of many different religions, races, languages, nations, and ethnicities within the British Empire. Recognition of this heterogeneity combined with sympathy for certain liberal traditions allowed those historical actors to engage with that imperial state and culture in ways that would have an impact on future generations and relevance to modern debates.
