The principality of Bushahr (also known as Bashahar, Bushahar, Bashahr) was once among the largest of the twenty-eight Shimla Hill States under the administration of the British Raj keen to invest on regional and transcontinental trade and exploit Himalayan resources. Caught in one of the British imperial enterprise, it was subjected to political-cum-economic vicissitudes, acceding to the Indian Union in 1947. On 8 March 1948, along with twenty other princely hill States of Punjab and Shimla, Bashahr signed an agreement which resulted in its inclusion in the Indian State of Himachal Pradesh.
