Alaeddin Pasha.

About Alaeddin Pasha

Alaeddin Pasha was the first Ottoman grand vizier. His father's name was Kemaleddin, and thus he was usually called Hacı Kemaleddin oğlu Alaeddin Pasha or Alaeddin bin Hacı Kemaleddin, meaning "son of Hacı Kemaleddin" He was probably from the town of Cendere, from where the famous Çandarlı family also originated. He was a faqih. He was appointed as the vizier during the last years of Osman I's reign. He continued during Orhan's Bey's reign. Since there was only one vizier in the divan during the early years of the Ottoman beylik, his title was not actually grand vizier, but his post was equivalent to the post of the later grand viziers. Because of this, he is known as the first grand vizier of the Ottoman Empire.
