The island is connected with Ghogha throughout its history. The island was under Muslim soldiers of Delhi Sultanate in early years of 14th century. In 1325, the island was captured by Mokhadaji Gohil, the Gohil chief of Umrala and ancestor of Bhavnagar State family. He made the island his headquarter, built a fort and levied toll from all ships passing up the Gulf of Cambay. He became a noted pirate in Gulf. His exactions came to the knowledge of the emperor Muhammad bin Tughluq of Delhi Sultanate who was then quelling a revolt in Gujarat. In 1347, Tughluq attacked Ghogha and killed Mokhadaji. He destroyed the fort of Piram island. He left Ghogha and Piram in the hands of Dungarji, Mokhadaji's son.

The island fell into obscurity after the destruction of the fort. In the middle of the eighteenth century (c. 1729), a merchant of Surat named Mulla Muhammad Ali, built a fort on Piram with an intention to establish himself as an independent chief. Subsequently it fell under the royal family of Bhavnagar State who had built a bastion on south west corner of the island to keep watch on the maritime activities. The British built the 24m high circular masonry lighthouse tower on the bastion in 1864-65 from the ruins of Mulla's bastion.
