By the end of November 1872, new problems emerged before the Spanish Government.
The development and construction across various regions of Spain were still progressing smoothly, with Madrid and Barcelona advancing by leaps and bounds, being hailed as the twin stars among the many cities of Spain.
Of course, the main reason was also because Spain's overall population was very small, with not a single city in the entire country having a population exceeding one million.
Currently, among all the major powers, the capital of the United Kingdom, London, was the most populous city, with a population approaching four million.
This population size was extremely exaggerated, comparable to small countries like the Netherlands and Belgium. But the actual population of the United Kingdom was no match for Germany and France or Austria-Hungary, which also demonstrated the dramatic industrial and economic development of London as the core city of the first industrial revolution.
