Alexei Navalny, Russia's most influential opposition leader in the past decade and a top political opponent of President Vladimir Putin, died in February.

According to his posthumous memoir, Navalny knew in advance that he was destined to die in prison. The book is going to be released on October 22.

Portions of the book were published by The New Yorker on Friday. It includes some of Navalny's diaries written while in prison and before.

On March 22, 2022, he wrote, "I will spend the rest of my life in prison and I will die here." There will be no one to say goodbye to. All the anniversaries will be celebrated without me. I will never see my grandchildren.

Navalny was serving a 19-year sentence in a penal colony in Meru. He was charged with extremism.

He died on February 16 at the age of 47. His death drew widespread condemnation, with many blaming Putin.

In 2020, Navalny suffered serious health complications due to poisoning. After returning to Russia in 2021, he was arrested.

On January 17, 2022, he wrote, We should have only one fear, and that is that we will be forced to surrender our motherland to a group of liars, thieves and hypocrites who will plunder it. As the loneliness of imprisonment emerges in his writings, there is also a hint of humor.

For example, on July 1, 2022, Navalny gave a summary of his daily life: woke up at 6:00 a.m., had breakfast at 6:20 p.m., and started work at 6:40 p.m. To work, you have to operate a sewing machine for seven hours sitting on a stool below knee height.

He also wrote that after work, he would sit for hours on a wooden bench under a wooden portrait of Putin. This is called punitive measures.

The book Patriot is being marketed by American publishing house Knopf. They also plan to publish a Russian version of it.
