Answer: Spanish
Explanation:
After Mexico achieved independence from Spain (officially in 1821), immigration to Mexico came essentially from Europe, especially from Spain, but also from France, Italy, Ireland, England and Germany.
It should be noted that between the 19th and 20th centuries, many of the immigrants in Mexico were Spanish, despite the resentment and suspicion towards them as a result of three long centuries of conquest. <u>This is because the Mexican governments of the newly established Republic wanted to attract a large foreign immigration to promote and consolidate the development of the nation. </u>In addition, they wanted to populate the vast territory of the north of the country and develop agriculture, for which they enacted laws and decrees that sought to encourage European immigration.
However, not all immigrants were Spanish; Americans, French, Germans, English, Italians and Russians arrived, among the most favored, as well as Japanese, Chinese and Korean. Also Lebanese and Jews, who along with the Chinese appeared in the markets much more modestly than the Europeans.
