The autobiography of Adolf Hitler published in 1926 reached "bestseller" status in Germany during the 2016 calendar year. After initially planning 4,000 copies, "Mein Kampf" is heading for its sixth print run, its publisher said Tuesday.

The Institute of Contemporary History of Munich reports that 85,000 copies of the new annotated version of the Nazi leader's novel had been sold since last January.

"It turned out that the fear the publication would promote Hitler's ideology or even make it socially acceptable and give neo-Nazis a new propaganda platform was totally unfounded," director Andreas Wirsching said in a statement.

"To the contrary, the debate about Hitler's worldview and his approach to propaganda offered a chance to look at the causes and consequences of totalitarian ideologies, at a time in which authoritarian political views and rightwing slogans are gaining ground."

"Mein Kampf" highlights Hitler's ideology and political views for the future of Germany.
