Question: Why didn't Tolkien like the title "The Return of the King"
About the article "The Lord of the Rings", section "Publication history".

Candidate passages:
Tolkien conceived of "The Lord of the Rings" as a single volume comprising six "books" plus extensive appendices.
The original publisher split the work into three, publishing the fifth and sixth books with the appendices under the title "The Return of the King".
Tolkien felt the chosen title revealed too much of the story, and indicated he preferred "The War of the Ring" as a title.
The proposed title for Book V was "The War of the Ring".
Book VI was to be "The End of the Third Age".
These titles were used in the "Millennium edition".
"The Return of the King" was in the end published as the third and final part of "The Lord of the Rings", on 20 October 1955. 
"The Return of the King" is the twelfth episode of the 2006 "Robin Hood" television series, made by Tiger Aspect Productions for BBC One.
It aired on Saturday December 23, 2006.
Its title punningly refers to the Tolkien book "The Return of the King".
It is the first part of the first series' only two-parter. 
The Tolkien Quizbook is the quizbook on the works of J. R. R. Tolkien officially sanctioned by the Tolkien Estate, written by Andrew Murray. 
In late 1969 or early 1970, Shippey wrote his first academic work on Tolkien.
He then held a speech at a Tolkien day organised by a student association.
This lecture, "Tolkien as philologist" became also influential for Shippey's view of Tolkien.
Joy Hill, Tolkien's private secretary, was in the audience and afterwards she asked him for the script, for Tolkien to read.
On 13 April 1970, Shippey received a seemingly formal letter from Tolkien.
The two, Shippey and Tolkien, first met in 1972.
Shippey was invited for dinner by Norman Davis who had succeeded Tolkien at the Merton Chair of English Language.
When he became a Fellow of St. John's College, Shippey taught Old and Middle English using Tolkien's syllabus.
Shippey's first printed essay, "Creation from Philology in "The Lord of the Rings"", expanded on his 1970 lecture.
In 1979, he was elected into a former position of Tolkiens, the Chair of English Language and Medieval English Literature at Leeds University.
His first book, "The Road to Middle-earth", was published in 1982.
At this time, Shippey shifted from regarding Tolkien as a philologist to a "traumatised author" as he called it.
This would include writers affected by war like Vonnegut and Golding.
Shippey appeared in several documentaries about Peter Jackson's "The Lord of the Rings film trilogy".
The dialect coaches were assisted by him and Shippey received a personal mention in the closing credits.
He summarised his experiences with the film project as follows: As an acknowledged expert on Tolkien, Shippey serves on the editorial board of "Tolkien Studies: An Annual Scholarly Review".
Shippey's education and academic career have crossed paths in many ways with that of Tolkien's: like Tolkien, he attended King Edward's School in Birmingham and both taught Old English at Oxford University.
Shippey also occupied Tolkien's former position at the University of Leeds and was responsible for changing the curriculum that Tolkien himself had instituted.
