How might the growth on industrialization have contributed to the popularity of the communist manifesto?

The growth of industrialisation led to a bigger gap between the rich and poor in society, making ideas such as communism and socialism that promised to shrink or close the gap popular with the lower classes. The need for working-class labourers in the new industrial factories also meant that more working-class people needed to be educated, allowing more poor people to read, to become conscious of themselves as a class, and to find solidarity with the ideas expressed in Marx's work.
