Majlis Khan Humayun was appointed by
Sultan of Bengal Saifuddin Firuz Shah to lead a military expedition into the territory of
Kamarupa. Crossing the vast
Brahmaputra River in 1491, Humayun's forces marched into what is now Jamalpur, Sherpur and
northern Mymensingh, successfully seizing Garh-Dalipa, a regional Koch stronghold of strategic importance and the site of
Chand Sadagar's
dinghy. Following the conquest, Humayun was entrusted with governing the newly annexed region. He is credited with establishing the
Bokainagar Fort and Tajpur forts, vital military and administrative centres that secured the Bengal Sultanate’s defence measures vis a vis the
Garo Hills. His administrative and military leadership helped solidify Sultan Firuz Shah’s control across this area during a time of regional upheaval. Located approximately six kilometres from modern-day Sherpur, Garh-Dalipa (Fort of Dalip) was renamed to Garh-Jaripa after the Muslim saint Jarip Shah, who is believed to have played a role in the establishment. Humayun named the fort after Jarip Shah, who only agreed to vacate his spot if the new settlement bore his name. The saint’s tomb, located on the eastern edge of Kalidah Sea, remains a
ziyarat site. ==Legacy==
