Lenin.

"Forgetting history means betrayal". In fact, the original saying is "Forgetting the past means betrayal." Many people think this is Lenin's famous saying. However, in fact, this is just a children's drama created in China. A line from Lenin in "In the Name of Revolution".

“Use copper as a mirror to correct your clothes, use ancient times as a mirror to understand the rise and fall, use people as a mirror to understand gains and losses, and use history as a mirror to understand the rise and fall.” It is one of the three lessons learned by Emperor Taizong of the Tang Dynasty. It reveals an irrefutable truth to people, that is: forgetting history is tantamount to betrayal.

If we Communists forget our own history, it will be tantamount to betraying our party’s century-old magnificent struggle, tantamount to betraying countless revolutionary ancestors who have sacrificed their lives and shed blood, tantamount to betraying Great communist belief. Therefore, the party history must not be forgotten, and it is just the right time to carry out party history study and education.

Lenin was the founder of the world's first socialist country and the founder of the world's first proletarian ruling party. He successfully led the Russian October Socialist Revolution and transformed socialism from scientific theory into great practice. As a new development and new achievement of Marxism in the era of imperialism and proletarian revolution, Leninism opened up the road to the nationalization of Marxism.

Lenin is generally recognized by communists around the world as "the great mentor and spiritual leader of the international proletarian revolution" and is one of the most influential figures in the 20th century.

"If we lose the memory of history, our hearts will be lost in the darkness." This famous quote by the famous Russian historian Klyuchevsky reminds the world of the meaning of "remembering".
