This is the great heroic story of Ertugrul Ghazi, the father of Osman who founded the Ottoman Empire. This series is created by Mehmet Bozdag (2014-19). The show is famous in Turkey & abroad particularly Pakistan and Azerbaijan but also has been banned in Arab countries and Fatawa has been issued against this show. The Prime Minister of the Islamic Republic of Pakistan Imran Khan praised the show and recommended people to watch it. Now officially, the series is broadcasting now on PTV in Urdu dubbing. Essentially, the show is about the Kayi tribe in the mid-1200s. The Kayis are a nomadic tribe of Turks who escaped from their ancestral homeland in Central Asia because of the Mongol invasions. They settled in territory controlled by the Seljuk Sultanate, but they ended up having to deal with both the Crusaders and Mongols even in their new home, as they struggled to survive and feed their people and animals. While this show is not about the Ottomans per se, the Kayi tribe is notable in history because one of their members ended up founding a small state that expanded over time and later became the Ottoman Empire. That person, of course, is Ertugrul. So a lot of the show is actually based on a true story, though obviously many details and storylines are embellished or made up.
