The spread of Islam in eastern islands of Indonesia is recorded in 1605 when three Islamic pious men collectively known as Dato' Tallu came to Makasar, namely Dato'ri Bandang (Abdul Makmur or Khatib Tunggal), Dato'ri Pattimang (Sulaiman Ali or Khatib Sulung) and Dato'ri Tiro (Abdul Jawad or Khatib Bungsu). According to Christian Pelras (1985), Dato' Tallu converted King of Gowa and Tallo to Islam and changed their name to Sultan Muhammad.
