Though he did not publish extensively during his lifetime, he has become arguably the most influential American historian of Islam due to his three-volume , which The University of Chicago Press, in collaboration with Reuben Smith and other colleagues, published after his death. The work is recognized as a masterpiece that radically reconfigured the academic study of Islam. Hodgson is also recognized for his work on world history, which was rediscovered and subsequently published under the editorship of Edmund Burke III. In The Venture of Islam, Hodgson positioned Islam as a spiritual endeavor with a profound moral vision--on par with other world religions. He also reimagined the terminology of Islamic history and religion, coining terms like Islamdom. Hodgson also resituated the geographical locus of Islam; he shifted attention away from an exclusive focus on Arab Islam that had characterized the Euro-American study of the religion to include the Persianate society, which shaped Muslim thought and practice from the Middle Period onward. Hodgson's writings were a precursor to the modern world history approach. His initial motivation in writing a world history was his desire to place Islamic history in a wider context and his dissatisfaction with the prevailing Eurocentrism and Orientalism of his day. Hodgson painted a global picture of world history, in which the "Rise of Europe" was the end-product of millennia-long evolutionary developments in Eurasian society; modernity could conceivably have originated somewhere else. Indeed, he accepted that China in the twelfth century was close to an industrial revolution, a development that was derailed, perhaps, by the Mongol onslaught in the thirteenth century: Hodgson denied original western exceptionalism and moved the divergence of Europe forward—from the Renaissance in the fourteenth century to the Scientific Revolution of the seventeenth century. His explanations for the divergence are rooted in the idea of a 'great Western Transmutation.' This is not to be confused with the Industrial Revolution, as it includes variables more diverse than just industry. Hodgson posited that all the societal elements of Western European nations became so advanced and co-dependent that those societies were able to determine their own rate of progress. The two most important influences on Hodgson’s thought were the French orientalist and priest Louis Massignon and the eighteenth-century American Quaker, John Woolman. From the former he learned empathy and respect for Islam, while the latter represented a critical view of Eurocentrism and an embodiment of Hodgson’s own Quaker conscience.
''Islamicate''
Hodgson introduced the term Islamicate to refer to characteristics of regions in which Muslims were culturally dominant, which were not, properly speaking, religious. For example, wine poetry was Islamicate, but not Islamic. This terminological distinction has not been widely adopted.
