Around 1260 AD, they moved down to the Gujarat coast and established three capitals; Sejakpur (present-day Ranpur), Umrala and Sihor.
In 1722–1723, forces led by Khanthaji Kadani and Pilaji Gaekwad attempted to raid Sihor but were repelled by Maharaja Bhavsinhji Gohil.
It remained a major port for almost two centuries, trading commodities with Mozambique, Zanzibar, Singapore, and the Persian Gulf.
The territory was further expanded by Bhavsinhji's grandson, Vakhatsinhji Gohil when he took possession of lands belonging to Kolis and Kathis, obtained Rajula from the Navab Saheb Ahmad Khan, and merged Ghogha Taluka into the state.
This made Bhavnagar the first state that was able to construct its railway system without any aid from the central government, which was mentioned in the Imperial Gazetteer.
This period produced some notable reforms in the areas of administration, revenue collection, judiciary, the post and telegraph services, and economic policy.
The two people who were responsible for those reforms were Mr E. H. Percival of the Bombay Civil Service and Gaurishankar Udayshankar, Chief Minister of Bhavnagar State Bhavngar Boroz.
While the State had long maintained an artillery, cavalry and infantry for defense and security, in 1866, these gave way to a body of police, which was found more suitable for keeping order in the towns and villages under the Thakur.
Nevertheless, during the First World War, the Bhavnagar Lancers were on active service in Egypt, Palestine and Mesopotamia, during which the unit gained a number of battle honors and some of its men received decorations for bravery in the field.
The royal family of Bhavnagar continues to lead an active role in the public eye as well as in business (hotels, real-estate, agriculture and ship breaking) and is held in high regard by the population both in the city as well as areas that comprised the princely state of Bhavanagar.
