In those two years, the Tatarian pressure on the West of the Khwarezmid State, West and North of Iran, diminished. They, rather, were satisfied with some campaigns at far intervals, and paid attention to establishing their sovereignty and power in the East part of the Khwarezmid State, in the regions of Amu Darya and Syr Darya, North of Afghanistan and East of Iran.

But those two years also witnessed something new, i.e. the sudden emergence of Jalaal Ad-Deen ibn Muhammad ibn Khawarizm Shaah on the scene, who previously fled to India five years ago, i.e. in 617 A.H. He was unable to live more in India, for his relations with its kings and rulers were not good. At the same time, he felt that the region of Persia was relatively left by the Tatars; and that Genghis Khan returned to his headquarters to deal with some of the affairs of his state, and left another commander to succeed him in leading the Tatarian armies.

Meanwhile, his brother Ghayyaath Ad-Deen took control of most parts of Persia, after his fighting with Sa‘d Ad-Deen ibn Dakla, which ended with an agreement of dividing the territories of Persia between them, and of course, Ghayyaath Ad-Deen received the greater share. This took place in 621 A.H., as referred to earlier.

Jalaal Ad-Deen felt that the conditions were suitable to return to the kingdom of Khwarezm in search for the lost sovereignty. But unfortunately, his view was not accurate, and he failed to diagnose the disease that befell the Islamic Ummah at that time. He did not know that among the causes that led the Muslim Ummah to that shameful state were division, dispersion, and carelessness about the blood of the opposing Muslims.

He indeed was unaware of those facts. For this reason, at the time he was supposed to exert effort to gather the fighting parties and bring together the conflicting regions, he entered the kingdom of Khwarezm while getting ready to be a new party in the Islamic conflict.
