During the third period, after a pause due to World War I, immigration to Argentina resumed and German speakers came in their largest numbers. This can be attributed to increased immigration restrictions in the United States and Brazil as well as the deteriorating conditions in post-World War I Europe. The two largest years of German immigration to Argentina were 1923 and 1924, with approximately 10,000 each year. This period is of particular interest because the older groups of German speakers began to feel a sense of cultural crisis due to the assimilation policies of the Argentine state, while the newcomers gave renewed life to German cultural institutions and created new ones. Between 1905 and 1933, the number of German schools rose from 59 to 176. Though found throughout Argentina, over 80% of these were located in Buenos Aires, Misiones, or Entre Ríos in 1933. Further, attendance at German schools rose from 3,300 in 1905 to 12,900 in 1933. Studies of this period inherently favor Buenos Aires, where half of all Germans lived, over the "colonias", where fewer institutions (particularly newspapers) developed.
