在革命斗争中，党弘扬坚持真理、坚守理想，践行初心、担当使命，不怕牺牲、英勇斗争，对党忠诚、不负人民的伟大建党精神，实施和推进党的建设伟大工程，提出着重从思想上建党的原则，坚持民主集中制，坚持理论联系实际、密切联系群众、批评和自我批评三大优良作风，形成统一战线、武装斗争、党的建设三大法宝，努力建设全国范围的、广大群众性的、思想上政治上组织上完全巩固的马克思主义政党。党从一九四二年开始在全党进行整风，这场马克思主义思想教育运动收到巨大成效。党制定《关于若干历史问题的决议》，使全党对中国革命基本问题的认识达到一致。党的七大为建立新民主主义的新中国制定了正确路线方针政策，使全党在思想上政治上组织上达到空前统一和团结。
In the course of the revolutionary struggle, the Party carried forward its great founding spirit comprised of the following principles: upholding truth and ideals, staying true to its original aspiration and founding mission, fighting bravely without fear of sacrifice, and remaining loyal to the Party and faithful to the people. The Party initiated and advanced the great project of Party building, introduced the principle of focusing on strengthening the Party in ideological terms, and upheld democratic centralism. It stuck to the three fine styles of conduct, namely combining theory with practice, maintaining close ties with the people, and conducting criticism and self-criticism; it developed the three important tools of the united front, armed struggle, and Party building, as it strived to build a national Marxist party of the people, which was fully consolidated in ideological, political, and organizational terms. The rectification movement—a Party-wide Marxist ideological education movement—was launched in 1942 and yielded tremendous results. The Party formulated the Resolution on Certain Questions in the History of Our Party, which helped the entire Party reach a common understanding of the basic questions regarding the Chinese revolution. At the Seventh National Congress, the correct line, principles, and policies were formulated for building a new-democratic China, and as a result the Party became united as never before in ideological, political, and organizational terms.

经过二十八年浴血奋斗，党领导人民，在各民主党派和无党派民主人士积极合作下，于一九四九年十月一日宣告成立中华人民共和国，实现民族独立、人民解放，彻底结束了旧中国半殖民地半封建社会的历史，彻底结束了极少数剥削者统治广大劳动人民的历史，彻底结束了旧中国一盘散沙的局面，彻底废除了列强强加给中国的不平等条约和帝国主义在中国的一切特权，实现了中国从几千年封建专制政治向人民民主的伟大飞跃，也极大改变了世界政治格局，鼓舞了全世界被压迫民族和被压迫人民争取解放的斗争。
On October 1, 1949, the founding of the People’s Republic of China was proclaimed after 28 years of bitter and courageous struggle carried out by the people under the leadership of the Party and with the active support of other political parties and democrats without party affiliation, thus realizing the independence of the Chinese nation and the liberation of the Chinese people. This put an end to China’s history as a semi-colonial, semi-feudal society, to the rule of a handful of exploiters over the working people, to the state of total disunity that plagued the old China, and to all the unequal treaties imposed on our country by foreign powers and all the privileges that imperialist powers enjoyed on our land, marking the country’s great transformation from a millennia-old feudal autocracy to a people’s democracy. This also reshaped the world political landscape and offered enormous inspiration for oppressed nations and peoples struggling for liberation around the world.

实践充分说明，历史和人民选择了中国共产党，没有中国共产党领导，民族独立、人民解放是不可能实现的。中国共产党和中国人民以英勇顽强的奋斗向世界庄严宣告，中国人民从此站起来了，中华民族任人宰割、饱受欺凌的时代一去不复返了，中国发展从此开启了新纪元。
It has been proven through practice that history and the people have chosen the Communist Party of China, and that without its leadership, it would not have been possible to realize national independence and the people’s liberation. Through tenacious struggle, the Party and the people showed the world that the Chinese people had stood up and the time in which the Chinese nation could be bullied and abused was gone and would never return. This marked the beginning of a new epoch in China’s development.
