Lom Sak (Thai:หล่มสัก,pronounced[lòmsàk]) is a district (amphoe) in the northern part ofPhetchabun province, northernThailand.
The history of Lom Sak area dates back to the founding of theSukhothai Kingdom in the 13th century. The governor ofMueang Rat (Lom Sak),Pho Khun Pha Mueang (พ่อขุนผาเมือง), was one of the Thai warlords who defeated the Khmer. When Pho Khun Bang Klang Hao (พ่อขุนบางกลางหาว) and a friend established the Sukhothai Kingdom, he supported his friend to be the first king because his wife was Khmer.
In 1767 in the reign of KingTaksin the Great, Phraya Chakri (the later KingRama I) returned from an expedition toVientiane through the area of present-dayLom Kao district. Some of the people from Vientiane settled there. When the new town grew bigger, they moved their town to the plain near thePa Sak River and named the new town Lom Sak. Later other Lao from Vientiane, who was forced by King Taksin to settle inLopburi, returned and settled in Lom Sak.
According to the historian PrinceDamrong Rajanubhab,Mueang Lom Sak was established in the reign of KingNangklao (Rama III). When KingChulalongkorn (Rama V) created themonthon as part of theThesaphiban administrative reforms,Mueang Lom Sak was controlled byMonthon Phetchabun. Later it was downgraded to be a district of Phetchabun Province. In 1916, the district was named Wat Pa (วัดป่า). The name was changed back to Lom Sak on 11 November 1938.
From 1970 to 1980 the hills of Lom Sak were a stronghold of theCommunist Party of Thailand.[citation needed]
Neighboring districts are (from the north clockwise)Lom Kao andNam Nao of Phetchabun Province,Khon San ofChaiyaphum province, andMueang Phetchabun andKhao Kho of Phetchabun.
Nam Nao National Park protects some of the hills of the district.Khao Kho National Park is currently being developed and will also occupy parts of the district.
