The largest number of Ukrainians migrated to Argentina between the two world wars. This wave of emigrants, whose number is estimated at between 50,000 and 70,000 people, was much more geographically diverse, and included many people from Orthodox areas of Ukraine such as Volhynia and Bukovina. It also included more educated or politically oriented people who had been involved in Ukraine's struggle for independence. Approximately half of this wave of immigrants settled in Buenos Aires, while the remainder strengthened the Ukrainian population in Misiones Province or created new Ukrainian settlements in other agricultural regions such as in Chaco Province.
