Emphasizing and strengthening patriotism education is an important magic weapon and fine tradition for the Communist Party of China to achieve great achievements in revolution, construction, and reform. A century of party history is a vivid history of patriotism education. In the past 100 years, the Communist Party of China has gone through four historical stages of patriotism education: the new democratic revolution, socialist revolution and construction, reform and opening up and socialist modernization, and the new era of socialism with Chinese characteristics. Over the past century, the Communist Party of China has accumulated rich experience in patriotism education, namely: insisting on using Marxism to guide the vivid practice of patriotism education; accurately grasping the key targets of patriotism education; insisting on the fundamental principle of a high degree of unity of love for the Party, love for the country and love for socialism; insisting on a broad historical perspective and integrating patriotism education into Party history learning and education, etc. Examining the historical process of the Party’s patriotism education in the past century and summarizing its basic experience is of great practical significance in promoting the innovative development of patriotism education in the new era.
