Which Oxford literary society did C.S. Lewis help lead with J.R.R. Tolkien?

C.S. Lewis helped lead the Oxford literary society known as The Inklings.

The Inklings was an informal Oxford literary discussion group active mainly during the 1930s and 1940s. Lewis and J.R.R. Tolkien were among its best-known members, and the group met at locations including Lewis’s rooms at Magdalen College and the Eagle and Child pub, popularly known as the Bird and Baby.

Members read drafts aloud, discussed literature, and offered criticism. The group was not a formal club with a fixed membership list or a published manifesto. Charles Williams, Owen Barfield, Warren Lewis, and other writers and scholars were also associated with it at different times.

The Inklings did not write The Chronicles of Narnia or The Lord of the Rings collectively. Rather, it provided a setting in which Lewis and Tolkien could test ideas and hear reactions to their own work. The society is therefore best understood as a major friendship and literary conversation, not a joint-authoring organization.
