The Princely State of Dhami, also known as Halog, was one of the native states of India during the rule of the British Empire in India. During the 19th century, the territory was appointed as one of the princely states of India under the indirect rule of the British Government. The state covered a total area of 28 sq miles and consisted of a total population of 5,114 in the year 1941. Dhami state was one of the 18 Shimla Hill States. The territory was located around 16 miles towards the southwest of Simla (Shimla). It was spread all through a gathering of mountain peaks of significant height, with superseding valleys. The former state was bounded by the Bhajji in the east and north; by the princely state of Baghal in the west; and by the princely state of Patiala in the south. The Princely State of Dhami included around 109 villages and was incorporated as a part of Punjab States Agency, which was a political office of the British Government of India that managed a collection of princely states of India.

History of Princely State of Dhami
The Chauhan Rajputs were the native rulers of the former state of Dhami. The ruling family was associated with the last Hindu king of Delhi, who was defeated in 1193 by the Mughal rulers. The family settled in the territory of Dhami during the 14th century. A feudatory of the princely state of Bilaspur first and then of Keonthal state, Dhami was seized by the Gurkhas at the commencement of the 19th century. In the year 1815, the princely state of Dhami became independent, which was recognized by the British administration.

The Princely State of Dhami was ranked 11th among the Shimla Hill States, until the abolition of the separate agency in 1936 and its inclusion in the Punjab States Agency. The region was segregated into 7 different parganas. The native ruler of Dhami, who held the title of Rana, took charge of the administration of the state and possessed full jurisdictional powers. Dhami state was one of the original constituent members of the Chamber of Princes, a number of smaller states indirectly represented by 12 princes who were elected periodically by them. According to the Attachment Scheme of 1943, the princely state of Dhami was attached to the princely state of Nalagarh, under the plan proposed by the Resident of British India for the Punjab States on April 17, 1944.

The last native ruler of the princely state of Dhami acceded the princely state to the Dominion of India, also known as Union of India, after the country gained independence from the British Dominion in the year 1947. Later in the year 1948, the region was incorporated as a part of the Indian state of Himachal Pradesh.
