What did Henrik Heine create in 1844 to express his dissatisfaction with the bourgeoisie?

1844, Silesia textile worker uprising broke out in Germany. Henrich Heine devoted himself enthusiastically to the revolutionary cause of the motherland and wrote many famous poems, including Silesia Textile Workers. After the revolutionary storm passed, Heine was greatly dissatisfied with the betrayal of the bourgeois democratic revolutionaries. The hope of victory was once again hidden in the thick darkness, and Heine fell into extreme depression. Heine was paralyzed in bed because of the deterioration of his condition. But our poet still maintains the passion of fighting and is full of resentment against the reactionary forces: "My heart was destroyed, my weapon was not destroyed, I fell but I did not fail." Heine in his later years was still full of confidence in capitalism and firmly believed that the future would be a working-class society. But at the same time, sensitive poets worry that the victorious proletariat will destroy their beautiful poems.
