​1075—A unique turning point in Seljuk history. On one hand, the impenetrable Tbilisi Walls of Georgia and the epic battle between the vast army of Sultan Malik Shah are being fought, and on the other hand, the most perfect calendar in the history of the world is being born in a secluded observatory by a scientist. Today's 19th episode is organized around the discovery of the incredible calendar by scientist Omar Khayyam and all the exciting events of Sultan Malik Shah's Caucasus expedition. ​What's in this episode: ​Omar Khayyam's Jalali Calendar: The story behind the creation of this calendar, which is more accurate than the modern Gregorian calendar. Why is it not even a day wrong in 5,000 years? Why did UNESCO recognize it as a world heritage site? ​The victory of science: How did Khayyam's star calculations and mathematics add a new dimension to the Seljuk military strategy? The Siege of Tbilisi: The epic strategy of the Seljuks amidst the rain of Greek fire and the icy currents of the Kura River. Tunnel War and Heroism: The commando operations of Emir Sautigin and Emir Gumushtigin and the deadly battle of the Georgian Royal Knights. Malik Shah's Justice: The historic and noble decision to release the fighting Georgian knights after the capture of Tbilisi as the victorious sultan. This chapter of 1075 was not just a geographical conquest, but rather an immortal heroic story that changed the course of history in the light of science. ​📌 Stay connected with us: Subscribe to the channel:    / @momrujmiahsumon-v2z   ​#TheGreatSeljuk #OmarKhayyam #JalaliCalendar #MalikShah #TbilisiSiege #HistoryOfIslam #MomrujMiahSumon #HistoricalDocumentary #SeljukEmpire #جالالی_كالیندار #ومر_كهیام #مالیک_شاه #يسلامی_یتۇحاس
