The Hill States of India were princely states lying in the northern border regions of the British Indian Empire.
Hill States of India Wikipedia
During the colonial Raj period, two groups of princely states in direct relations with the Province of British Punjab became part of the British Indian Empire later than most of the former Mughal Empire, in the context of two wars and an uprising.
For its princely rulers the informal term Hill Rajas has been coined. After the independence and split-up of British India, the Hill States acceded to the new Union of India and were later divided between India's constituent states of Punjab (proper), Haryana and Himachal Pradesh.
28 princely states (including feudatory princes and zaildars) in the promontories of the western Himalaya were named after Shimla as the Simla Hill States. These states were ruled mainly by Hindu Rajputs. Their inhabitants were mainly Hindu with a few Buddhists; the local languages were Hindi, Punjabi, Urdu and various Pahari dialects.
Three quarters of the about 4,800 square miles (12,000 km2), on both sides of the Sutlej river, was the territory of the Raja (earlier Rana) of Bashahr. The direct tributaries of Bashahr were:the Thakur of Khaneti
the Thakur of Delath.
The other, all far smaller, princely states, including a few with some petty dependencies of their own, were further south, on the left bank of the Sutlej:the Rana of Balsan
the Thakur of Beja
the Rana of Bhaji /Bhajji
a prince of Bhagat
the Raja of Bilaspur (formerly Kahlur = Kehloor), entitled to an 11-guns salute
the Rana of Darkoti(i) = Darkoti
the Rana (Shri) of Dhami
the Raja Rana (ex Rana) of Jubbal. The Jubbal state had two tributaries:
the Thakur (sahib) of Dhadi State, initially tributary to Tharoch, then to Bashahr and finally in 1896 to Jubbal.
(title?) Rawin = Rawingarh
the Raja (formerly Rana) of Keonthal. Furthermore, the feudal pyramid included five Keonthal zaildars (jagirdars collecting a special tax):
a jagirdar Gundh
the Rana Sahib of Koti (since 1815)
a jagirdar Madhan = Kiari
the Thakur Saheb (also styled Rana) of Ratesh (popularly known as Kot, 'fortress')
the Rana of Theog
the Thakur of Kunihar
the Rana of Kuthar
the Thakur of Mahlog

the Thakur (or Rai Mian?) of Sangri
the Thakur (originally titled Rana up to the occupation by the Gurkhas; Thakurs from 1815 to 1929) of Tharoch = Tiroch
NB - For various of the entities above, the authentic title of the chieftain is missing. While some of the lowest ranking may have had none, for the princes that can merely be due to insufficient sources available
The princely states of the Simla Hills all ultimately became part of the modern Indian state of Himachal Pradesh.
Some nearby Hindu and Sikh states include :HH the Raja (Saheb) of Chamba, entitled to an 11 gun salute
HH the Raja of Mandi, entitled to an 11 gun salute
HH the Raja of Suket, entitled to an 11 gun salute
HH the Maharaja (until 1913 Raja) of Tehri Garhwal State (in Uttar Pradesh), entitled to an 11 gun salute
