According to the
Marathi-language text
Mahikavatichi Bakhar (c. 1448 CE), the city and the kingdom of Mahikavati were established in the 12th century by Pratap Bimb, a brother of the king of
Champaner. After a successor of Pratap Bimb died heirless, Nagar-shah of Ghandivi (
Gandevi) captured Mahikavati. The
Yadava king
Ramdev-rao tried to capture Mahikavati, with support of Nagar-shah's rebel relatives, but the attack was repulsed. Subsequently, the Delhi Sultan
Ala-ud-din defeated and killed Ramdev-rao. Ramdev-rao's son Keshavdev regained control of the Yadava capital Devagiri, and his other son Bimb-dev - the governor of
Udgir - launched a military campaign against Ala-ud-din. During this campaign, Bimb-dev reached northern Konkan, where he defeated several small chiefs, and forced Nagar-shah to flee. With support of the local elites, Bimb-dev ruled his newly-conquered territory from Mahikavati. Later, Nagar-shah's forces, led by his son Tripurkumur, defeated the army of Bimb-dev's son Pratap-shah and regained control of the area. Soon after, Ala-ud-din Khalji ended the Yadava rule at Devagiri, thus leaving Nagar-shah firmly in control of the present-day Mumbai area. Another Marathi-language account of Bhima is found in
Biṁbākhyāna or
Bimbakhyan ("The story of Bimba"), a poetic version of
Mahikavatichi Bakhar, present in the archives of the
Bharat Itihas Sanshodhak Mandal, Pune. This manuscript was authored by Lakṣumaṇa (Laxman) Prabhu. It states that the king Bimba-dev came to
Konkan travelling through
Anahilavada in 1294 CE (1216
Shaka). He was accompanied by a number of people, who had left the kingdoms of Anahilavada and Devagiri because of
Muslim invasions. Bimba halted at
Mahim, then an island, and became enamoured with its beautiful scenery. He built a palace on the island, and his followers also built their residences there. Another manuscript from the Bharat Itihas Sanshodhak Mandal archives, copied by Naranji in 1798 CE, also mentions king Bimba. The first chapter of this manuscript, titled
Shree Ram Mahima and dated 1388 CE, states that Ram
Raja - the father of
Raja Bimba - came to Konkan around 1144 CE from the "five Paithans", namely
Champaner,
Hastinapur, Nagabaj, Mangi Paithan, and
Panhala. The second chapter (dated 1614 CE) and the fifth chapter (undated) mention Bimba. == Persian-language accounts ==
