The father of the Ottoman Empire Osman Gazi was born in 1258 in the town of Sogut. His father was Ertugrul Gazi and his mother was Hayme Sultan. Osman Gazi was a tall man with a round face, dark complexion, hazel eyes, and thick eyebrows. His shoulders were fairly large and the upper part of his body was longer than the other parts. He used to wear a Horasan crown in the style of Cagatay, which was made of red broad cloth.
Osman Gazi was a brilliant leader. He was fair, brave and gracious. He helped the poor. Sometimes he gave his own cloths to the poor. Every mid-day, he gave a lavish meal to all people in his house.
Osman Gazi was just 23 when he succeeded the leadership of the Kayi Clan in Sogut, in 1281. He was a very brilliant rider and a fencer. He married to Mal Sultana who was the daughter of famous Omer bey. Mal Sultan gave birth to Orhan who succeeded the throne.
Osman Gazi appreciated the opinions of Edebali (the famous Ahi Sheik) and he respected him. He often went to Edebali�s house where a dervish group meets in Eskisehir Sultanonu and been his guest.
One night, when he was a guest in Sheik Edebali�s dergah, he had a dream. As the sun shined, he went to Edebali and told him: �My Sheik, I saw you in my dream. A moon appeared in your breast. It rose, rose and then descended into my breast. From my novel there sprang a tree. It grew up and turned green. It branched out and got complicated. The shadow of its branches covered the whole world. What does my dream mean ?�
After a little silence, Seyh told him :
� I have got good news Osman! God gave you sovereignty and to your son. All the world will be under the protection of your son and my daughter will be the wife to you.�
After this unusual event, the Sheik gave his daughter Bala Sultana to Osman and Alaeddin was born from this marriage.
