Pithoragarh (Kumaoni: Pithor'garh) is a Himalayan town with a Municipal corporation in Pithoragarh district in the Indian state of Uttarakhand. It is the largest hill town in Uttarakhand.

Tradition has it that during the reign of the Chand Rajas of Kumaon, one Piru, also called Prithvi Gosain, built a fort here and named it Prithvigarh which, in the course of time, got changed to Pithoragarh.

Pithoragarh city and its surrounding areas were part of the Manaskhand region, which extended from the Kailash Mountain in the north to Bhabar & Terai in the south, as mentioned in the Skanda Purana. The Asuras and Nagas appear to be the earliest inhabitants of the region, who were later superseded by the Kiratas, Khasas and the Kunindas. The Kuninda Kings of the region may have become the feudatories of The Kushana Kings, who held their sway over the region in the last quarter of the 1st century AD.

The region subsequently came under the Kurmanchal kingdom, which had its capital first at Jyotirmath and then at Karikeyapura (Modern day Baijnath) in the Katyur Valley. The Group of Temples at Kasni village (3 km from city centre) were built in 11th century during the rule of Katyuri kings.

Upon the disintegration of the Katyuris and fall of kingdom in 13th century, Pithoragarh came under the rule of Bam kings of Saur. The Bam kings were feudal to the Raikas of Doti and was a branch of katyuri kings, and had their capital at Udaipur near Pithoragarh, However, the Rajas used to come down to Rameshwar and Bailorkol during the winter months. The Bam kings, who ruled over Saur were:

In the fifteenth century, King Bharti Chand of Champawat amassed a huge army, and started plundering and killing in the regions ruled by the Doti Kings. This resulted in a war, which lasted for 12 years, and ended with a victory for the Chands. After the death of Bharti Chand in 1462, Nagmalla, the king of Doti attacked his son, Ratna Chand who was successful in defending himself. Nagmalla was killed in the war and the Bams became feudatories of the Chands. The pargana of Saur came under direct control of the Kingdom of Kumaon in the sixteenth century during the rule of King Balo Kalyan Chand, when it was given to him by the Raika king of Doti as dowry for marrying his Daughter.

In 1790, the Chand kings built a new fort on the hill where the present Girls Inter College is situated. This fort was destroyed by the Indian government in 1962 after China attacked India.^[why?] The Chand rule, at its zenith, is seen as one of the most prominent empires in Kumaon. Their rule also coincides with a period of cultural resurgence. Archeological surveys point towards the development of culture and art forms in this period.

A Branch of Indian National Congress was established in the region in 1912, and in 1916, many people from Pithoragarh attended the Lucknow session of Congress. The Non-cooperation movement was started in the region in 1921 and in 1930, 10 people from Pithoragarh participated in the Civil disobedience movement. Subsequently, the Congress won the Pithoragarh seat in the Provincial Elections in 1937. The Quit India Movement of 1942 found greater support in Pithoragarh and about 150 persons were arrested while several were fined. The Congress won the Pithoragarh seat again in the General Elections of 1945 for the Provincial Assembly, and in 1947, along with the rest of India, this region also won independence from the British Rule.
