Osman is known as the father of the Ottoman Empire as from his Beylik (principality) the expansion of the Ottoman territory began. In the history books you will often see Ottoman rule referred to as the Osmanli dynasty. Osman came very late to his parents. He was born late in Ertugrul and Halime’s life. When Osman was born, (1258), Ertugrul was around 67 years old, and as Halime was older too, when normally women cannot have children anymore, he was considered as a Miracle sent by God. Historians consider a black hole in Ottoman history during Osman’s life as what is written about him was uncovered 100 years after he died.
