In a.h. 620 (a.d. 1223) Sultan Jelālu-’d-Dīn...

In a.h. 620 (a.d. 1223) Sultan Jelālu-’d-Dīn, the dispossessed monarch of Kh’ārezm (Chorasmia) was killed in a battle fought by him in Azerbāyjān (Atropatene) against the Sultans of Rome, Syria, and Egypt, when his forces were totally defeated. And thus ended that great dynasty, after ruling about a hundred and forty years.

Bahā’u-’d-Dīn went from Malatia and remained four years near Erzinjān (the ancient Aziris, on the Western Euphrates), in Armenia, at a college built for him by a saintly lady, ‘Ismet Khātūn. She was the wife of the local sovereign, Melik Fakhru-’d-Dīn. She and her husband both died, and then Bahā’u-’d-Dīn passed on to Larenda (in Cataonia), in Asia Minor, and remained there about seven years at the head of a college, the princess Melika'i-Jihān, his mother, being still with him.

Here it was that his younger son, Jelālu-’d-Dīn Muhammed, the future author of the Mesnevī, attained to man's estate, being then eighteen years old; when, in a.h. 623 (a.d. 1226), he married a young lady named Gevher Khātūn, daughter of the Lala Sherefu-’d-Dīn, of Samarqand. She gave birth in due course to Jelāl's eldest son, ‘Alā’u-’d-Dīn. The king had now returned to his capital, Qonya (the ancient Iconium).

Hearing of Bahā’u-’d-Dīn's great learning and sanctity, the king sent and invited him to the capital, where he installed him in a college, and soon professed himself a disciple. Many miracles are related as having been worked at Qonya by Bahā’u-’d-Dīn, who at length died there on Friday, the 18th of Rebī‘u-’l-ākhir, a.h. 628 (February a.d. 1231). The Sultan erected a marble mausoleum over his tomb, on which this date is recorded. Many miracles continued to occur at this sanctuary.

The Sultan died also a few years later, in a.h. 634 (a.d. 1236). (After the death of Bahā’u-’d-Dīn Veled, and the acquisition of still greater fame by his son Jelālu-’d-Dīn, who received the honorific title of Khudāvendgār- Lord -the father was distinguished from the son, among the disciples, by the customary title of Mevlānā Buzurg- the Greater or Elder Master .
