the region of javali in the satara district was important from the strategic point of view. many routes to the konkan were through javali. for the expansion of the swaraj in the konkan, it was essential to control that region. the region of javali was ruled by chandrarao more, a powerful sardar in the adilshahi. shivaji maharaj attacked javali and captured it in a.d. 1656. then he also captured rairi. this strong fort, later under the name of raigad, was to become the capital of shivaji maharaj. shivaji maharaj built the pratapgad fort in the javali valley to protect the newly conquered territory and to control the paar pass. the victory at javali led to the expansion of the swaraj in konkan. shivaji maharaj then crossed the ghats and descended into konkan. he captured kalyan and bhivandi on the konkan coast which were under the control of adilshahi. shivaji maharaj also captured forts like mahuli, lohagad, tunga, tikona, visapur, songad, karnala, tala and ghosala, in the konkan. shivaji maharaj was able to command the coast line because of his acquisition of this territory in the konkan. he came in contact with the portuguese, the british and the siddi powers on the western coast. the siddi controlled the fort of janjira and the areas around, including danda-rajpuri. wherever in future these powers created obstacles in the work of expanding the swaraj, shivaji maharaj tried to curb their activities.
