Thonglun province under Sukaphumese rule
In the 1850s, the Lom Kingdom established plans for an invasion of Wanh. In Guwol of 1868 Lomtai invaded western Wanh, three months later in Sibiwol, Vạn Xuân declared war on Lomtai. Sukaphum is initially neutral, though after the Lom invasion of Tonklakatomnam and the Battle of Pratuhup in 1870, Sukaphum allies with Vạn Xuân against Lomtai. The war would end in Parwol of 1875 when Sukaphumese and Vạn Xuânese military laid siege to Banvuchuan, and forced Lomtai to surrender to the terms of the Treaty of Banvuchuan. Shortly after Lomtai’s surrender, Lomtai retracted all remaining forces from Wanh, and Sukaphum and Vạn Xuân followed by removing all of their military presence from Lomtai. Per terms of the Treaty of Banvuchuan, Lomtai ceded the entirety of the province of Thonglun, as well as small portions of Phaylin province and Nasay province to Sukaphum. Together these territories formed the Sukaphumese province of Pratuhup.

Pratuhup province (谷門 ; : จังหวัดประตูหุบเขา, "Changwat Pratuhup"; : ແຂວງປະຕູຮ່ອມ, "Aekhuang Patuhom") was a provinces in northeast Sukaphum from Parwol, 1875 to Chirwol, 1940. It consisted of the territories ceded to Sukaphum by Lomtai at the end of the Khon Pa War (1868 – 1875). The capital and largest city of Pratuhup province was Pratuhup city (Patuhom), after which the province is named. Beginning in the 1900s, Pratuhup province became {[wp|gentrification|gentrified}} by upscale, wealthy Sukaphumese, causing many ethnic Loms to immgrate to Lomtai.
