Doti was one of eight different princely states the Katyuri Kingdom was divided into eight for their eight prince's and became different independent kingdoms; Baijnath-Katyuri, Dwarahat, Doti, Baramandal, Askot, Sira, Sora, Sui (Kali Kumaon). Later on, the whole land between Ramganga on the west (Uttarakhand) and the Karnali on the east (which divides the far western region from other parts of Nepal), came under the Raikas after the origin of Raikas of Katyuris in Doti.

Kings of Doti were called Raikas (also Rainka Maharaj).

During the period of Akbar's rule in the 16th century, the Mughals had attacked the Raikas of Doti. They invaded Ajemeru, the capital of the Raika Kingdom. Ajemeru is now in Dadeldhura District of the far western region of Nepal. Hussain Khan, army chief of Akbar residing in Lucknow had led the attack. According to `Abd al-Qadir Badayuni (c. 1540–1615), Indo-Persian historian during Mughal Empire, Mughal Army chief of Lucknow, Hussian Khan, lured by the wealth and treasures of the kingdom of the Raikas, wanted to plunder the region, this being the motive behind the assault, but they did not succeed.
