In the practice process of leading the proletarian revolution, Marx and Engels constantly innovated the party’s organizational form, guiding ideology and action strategy, which enriched the meaning of the unity and solidarity of proletarian party. They deeply realized the importance of the unity and solidarity of the proletarian party, which was not only the key and bond for uniting the proletarians, but also the necessity to mediate the competition among the workers and avoid them being split by the bourgeoisie. In answering the multiple relations of solidarity and autonomy, solidarity and struggle, solidarity and principle, solidarity and authority, Marx and Engels revealed the methodology of how to maintain the unity and solidarity of the proletarian party. Based on the current situation of the era and focusing on the new conditions of the world, of China and of the Party, it is still of important implications to review and study Marx and Engels’s thoughts for strengthening the Party building in the new era.
