Sultan Agung of Mataram - Territorial Conquests

Territorial Conquests

Sultan Agung attacked Surabaya in 1614, in addition to Malang which lie south of Surabaya, and the eastern end of the Java island. In 1615, he personally led the conquest of Wirasaba (present day Mojoagung, near Mojokerto). In 1616, Surabaya attempted to attack Mataram in retaliation, but lacking allies the Surabaya army was crushed by Sultan Agung's forces in Siwalan, Pajang (near Surakarta). The coastal city of Lasem, near Rembang, was conquered in 1616, and Pasuruan, south-east of Surabaya, was taken in 1617. Tuban, one of the oldest and biggest cities on the coast of Java, was taken in 1619.

Surabaya had been Mataram's most formidable adversary thus far. Agung's grandfather, Senapati or Senopati, had not felt strong enough to attack this powerful city, and his father, Seda ing Krapyak, attacked it to no avail. Sultan Agung weakened Surabaya by capturing Sukadana, Surabaya's ally in southwest Kalimantan, in 1622, and the island of Madura, another ally of Surabaya, in 1624 after a fierce battle. After five years of war Agung finally conquered Surabaya in a siege in 1625. With Surabaya brought into the empire, the Mataram kingdom encompassed all of central and eastern Java, and Madura, except for the west and east end of the island and its mountainous south (except for Mataram, of course). In the west Banten and the Dutch settlement in Batavia remained outside Agung's control. He tried in 1628-29 to drive the Dutch from Batavia, but failed. On August 27, 1628 he led the Siege of Batavia, which was unsuccessful.
