The Nazis did not erase Renia Spiegel’s life.

Her diary, 700 pages across thread-bound school-exercise books, includes her final entry, on July 25, 1942. Five days later, the Polish adolescent was shot to death by Nazis after being discovered in hiding. She was 18.

Nearly 80 years later, the world will know her haunting story.

The journal, already published in Poland where it has spawned a national poetry competition and drew comparisons to Anne Frank’s “The Diary of a Young Girl,” is set to be published in English by Penguin Books this month.

“ ‘Renia’s Diary’ is already being described as a classic of Holocaust literature,” reads the Penguin synopsis. “It is an extraordinary testament to both the horrors of war, and to the life that can exist even in the darkest times.”

The historical document was kept in a bank vault by Spiegel’s younger sister, who now goes by Elizabeth Bellak.

“I still find it difficult to look at,” Bellak told The Post last year. “It’s very painful for me.”

“We went through such terrible times together and now the most terrible moment is upon us,” Spiegel wrote to her diary. “Into your hands I commit myself. You will help me.”

“Renia’s Diary: A Holocaust Journal” is currently available for preorder via Amazon. The historical document will include a prologue and epilogue by Bellak.
