Amb was a princely state of the former British Indian Empire ruled over by the Tanoli tribe. Following Pakistani independence in 1947, and for some months afterwards, Amb's Nawab remained unaligned. However, at the end of December 1947 he acceded to Pakistan, while retaining internal self-government. Amb continued as a Princely state of Pakistan until 1969, when it was incorporated into North West Frontier Province (now Khyber-Pakhtunkhwa).
In 1972, recognition of the royal status of the Nawab was ended by the Government of Pakistan.
