After Napoleon lost his power there were no significant changes in the organization of the city until Rome became the capital of the newborn Italy. The needs of the new capital caused a great urbanization and an increase of the population, both within the Aurelian walls and outside them. In 1874 the rioni became 15, with the addition of Esquilino, created by taking a portion from Monti. At the beginning of the 20th century some rioni started being split up and the first parts outside the Aurelian walls started being considered part of the city.
