Alaeddin Pasha (vizier)
 Alaeddin Pasha was the first Ottoman grand vizier. His father's name was Kemalettin and thus he was usually called Hacı Kemalettin oğlu Alaeddin Pasha or Alaeddin bin Hacı Kemalletin meaning son of Hacı Kemalettin's. He was probably from the town of Cendere from where the famous Çandarlı family also originated. He was a fakih (expert in Islamic law). He was appointed as the vizier during the last years of Osman I's reign (probably in 1320). He continued during Orhan's Bey's reign.
