Masaie Matsumura, "The History of the British Empire Expositions: A Tale of Two Cities, London and Manchester" - A book to learn about the connection between the Expo and Manchester!
The book will be a work that looks at the connections between the London Expo and the Manchester Meiho Expo from a larger perspective, and from there at the connections to Japan.
Manchester is often seen as a disastrous result of the Industrial Revolution, but in fact, the Manchester Expo was also related to the movement to improve the lives of the people.
Marx has been in England since 1849 and, as for Engels, much longer than that. The background to the emergence of their ideas is the social situation in England. I found this book very helpful in understanding such social conditions in England.
