Alaeddin Pasha.

About Alaeddin Pasha

Alaeddin Erden Ali Pasha, was the son of Osman I, the first Ottoman ruler, and the half-brother of Orhan I, who succeeded their father in the leadership of the Ottoman Empire. His mother was Rabia Bala Hatun, daughter of Sheikh Edebali. It is not certain whether Alaeddin or Orhan was the elder son. Some historians claim that Alaeddin was Osman's second son, but others argue that there is a good chance that he was the oldest. Nevertheless, Orhan ruled the country and became the first Ottoman ruler to take the title of Sultan. According to tradition and Ottoman historiography as presented by historian Idris Bitlisi, Alaeddin was more passive than his warrior brother, and thus stayed at home instead of fighting to expand the newly forming Ottoman Empire. He received training in the management of the state affairs. There is a good chance that Orhan was selected to inherit leadership of the Empire because of his skills as a warrior.
