This paper analyses some of the various implications of the migratory flow from the main countries supplying workers during the period known as the new emigration: Italy, Spain and Portugal. Considering their peculiarities, the objective is to identify the strategies of each country that transformed this movement into a factor of economic development: conquest of markets, creation and promotion of colonies, use and protection of remittances from emigrated ones. With its kingdom in formation, and the largest source of emigrants, Italy had naturally followed the paths that revealed emigration as one of the agents of national prosperity, in contrast to Portugal and Spain.
