A Croatian Jesuit Nikola Plantic (born in Zagreb, 1720-1777) studied in Zagreb, Graz, Vienna and Trnava in Slovakia. He was teaching logic and philosophy at the Jesuit University in Cordoba in Argentina.

In some books we can read that Plantic allegedly had an important role in the formation of the unique Jesuit Kingdom in Paraguay, established for the wellbeing of native Guarani Indians. It is true that the Jesuits managed to organize prosperous economic and cultural life, including printing in the Guarani language. This was too much for great forces, since this Jesuit-Indian Republic had shaken the existing “world order.” The rebellion was put down in 1767, which led to the tragedy for Guaranis. The “international community” managed to achieve interdiction of the Jesuit order in 1773. But the claim that N.Plantic organized the rebellion is false. Some sources even claim that the Jesuit Republic was led by Plantic, and that allegedly a coin was issued with his figure in the Netherlands. Plantic was never in Paraguay, and never met Guaranis in their homeland. I owe this info to Mr. Joza Vrljicak, director of Studia Croatica, Buenos Aires. The only Croat known to have participated the famous Paraguay mission was Ivan Krstitelj Marchesetti (or Marqueseti, 1704-1767), born in Rijeka in a noble family having Italian roots, later croatized.
