Why did the novel the road win the Pulitzer prize?

Harper Lee's first and only novel, To Kill a Mockingbird,won the 1961 Pulitzer Prize for Fiction.

The book was popular with readers and became an immediate commercial success, aided by praise from prominent newspapers and periodicals. Time Magazine summarized the book's appeal in an August 1, 1960 review, "Author Lee, 34, an Alabaman, has written her first novel with all of the tactile brilliance and none of the preciOSity generally supposed to be standard swamp-warfare issue for Southern writers. The novel is an account of an awakening to good and evil, and a faint catechistic flavor may have been inevitable. But it is faint indeed; Novelist Lee's prose has an edge that cuts through cant, and she teaches the reader an astonishing number of useful truths about little girls and about Southern life."

Both the Literary Guild and Reader's Digest chose To Kill a Mockingbird as one of their book club selections, ensuring wide readership.

The 1961 Pulitzer jury penned the following notes in their recommendation to the Pulitzer Prize Board:

"...certain novelists, whose earlier work had aroused our hopes, published disappointing books during the year [referring to 1960]. William Styron's long-awaited Set This House on Fire and John Updike's Rabbit, Run both lavished major talents on minor themes... Fortunately, however, the stream of new talent which constantly revitalizes American fiction produced at least two first novels of unusual distinction. The first and more ambitious of these was To Kill a Mockingbird by Harper Lee. Set in her native Alabama, the book sums up in its seemingly artless tale the pride and shame that are integral to Southern living... This is our choice for the Prize."

To Kill a Mockingbird won the 1961 Pulitzer Prize because the jurists recognized Harper Lee's compelling story as an honest commentary on life and racism in the South, published during an era when the Civil Rights Movement was challenging Jim Crow and the unfair treatment of African-Americans in the US.
