Servare et Manere is planning a major expedition to Oceania in June 2022. We would like to connect this part of the Tree of Peace initiative in Oceania with the most important Slovak in the modern history of our nation: General Milan Rastislav Štefánik, soldier and astronomer. This year marks the exact 111^th Anniversary of Štefánik’s visit to Oceania. On our journey we will gradually visit Fiji, New Zealand, Australia and French Polynesia. We will also plant our Trees of Peace everywhere in these places.
