Which group did C.S. Lewis belong to with J.R.R. Tolkien and Charles Williams?

C.S. Lewis belonged to The Inklings with J.R.R. Tolkien and Charles Williams.

The Inklings were an informal literary discussion group associated with Oxford. Members and guests met to read aloud and discuss works in progress, poetry, mythology, and Christian literature. Lewis and Tolkien were among the best-known participants.

The group was active mainly during the 1930s and 1940s and met in locations including Lewis’s rooms at Magdalen College and the Eagle and Child pub, popularly known as the Bird and Baby. Charles Williams became an important member after moving to Oxford during the Second World War.

The Inklings were not a formal society with a membership register or published manifesto. That is why the group is sometimes misleadingly described as an official literary club. Its importance came from sustained friendship, criticism, and encouragement among writers.
