Inayatullah Khan Seraj (October 20, 1888 – August 12, 1946) was the King of Afghanistan from 14 January 1929 to 17 January 1929. He was the son of former Afghan King, Habibullah Khan. Inayatullah's brief reign ended with his abdication.
In the middle of the night, on January 14, 1929, Amanullah Khan handed over his kingship to his brother Inayatullah Khan Seraj and tried to secretly escape Kabul towards Kandahar. However, Habibullāh Kalakāni and his followers chased Amanullah's Rolls Royce on horseback but Amanullah managed to escape.
With the King gone, Habibullah Kalakani wrote a letter to King Inayatullah to either surrender or prepare for war. Inayatullah's response was that he had never sought nor wished to be king and agreed to abdicate and proclaim Habibullah Kalakani as king on January 18, 1929. Inayatullah was airlifted out of Kabul by the Royal Air Force and spent the remainder of his life in exile.
