Abstract:To build a modern socialist country in an all-round way and to a long-term ruling Marxist party, we must remain confident in our history. This confidence, a spiritual quality, has developed from a unique logic. Over the past century, the CPC has been committed to the ideals and beliefs of Marxism and communism, being confident in victory, showing lofty ambitions, and giving historical confidence soul and direction. The revolutionary heroism of building the CPC for the public interest, being brave and tenacious, not afraid of sacrifice, and optimistic encodes unyielding character, providing a selfless tone for historical confidence. Adhering to the “two combinations” of Marxism, and constantly promoting localization and modernization of Marxism in China shows extraordinary theoretical courage, laying a solid theoretical foundation for historical confidence. The strict organizational framework and strong party members have gained extensive popularity, providing a strong organizational guarantee for historical confidence. Putting people first and staying true to the abiding mission of serving the people wholeheartedly exhibits awe-inspiring righteousness, defining the fundamental value for historical confidence. Accentuating self-revolution and promoting the CPC’s self-revolution in the process of innovating on the basis of what has worked in the past makes the CPC thrive and breathes life into the historical confidence.
