Sumpah Pemuda or The Youth Pledge was a declaration made on 28 October 1928 by young Indonesian nationalists at a conference in the then-Dutch East Indies. They proclaimed three ideals, one motherland, one nation and one language.
In Indonesian, with the original spelling, the pledge reads:
Kami poetera dan poeteri Indonesia, mengakoe bertoempah darah jang satoe, tanah air Indonesia.
Kami poetera dan poeteri Indonesia, mengakoe berbangsa jang satoe, bangsa Indonesia.
Kami poetera dan poeteri Indonesia, mendjoendjoeng bahasa persatoean, bahasa Indonesia.
We the sons and daughters of Indonesia, acknowledge one motherland, Indonesia.
We the sons and daughters of Indonesia, acknowledge one nation, the nation of Indonesia.
We the sons and daughters of Indonesia, respect the language of unity, Indonesian.
Selamat Hari Sumpah Pemuda! Salam Mahasiswa!
