attributed to Admiral Cheng Ho's diplomatic efforts to ensure the security of ethnic Chinese in the Majapahit region. During the War of Regreg (1406), around 170 delegates from the Ming Dynasty were sent by Admiral Cheng Ho to re-establish diplomatic relations between China and Majapahit after the conflict of the Jayakatwang-Raden Wijaya-Kublai Khan in the era of transition from Singhasari to Majapahit. However, all the envoys were massacred by King Wikramawardhana who could not distinguish their arrival status as an enemy or not. The role of Admiral Cheng Ho was also significant for the Malang region (Tumapel) in 1432 when he was with his subordinates, Gan Eng Cu and (Duke (Bhre) of Arya Teja I of Tuban) and his younger brother, Gan Eng Wan, helped Ratu Maharani Sri Suhita (1429–1447 AD ) to unite Daha (Kadiri) and Tumapel after internal conflict. For his services, Bro Eng Wan was given the title Raden Arya Suganda was appointed as an official at Tumapel. Sengguruh Kingdom Sengguruh is the last Hindu kingdom and the rest of the heritage of Majapahit sympathizers in Malang. He was an independent kingdom after the fall of Majapahit. Hermanus Johannes de Graff argued that the son of the Brawijaya VII, Raden Pramana fled to the remote mountain region in the south due to the occupation of Daha (Kadiri) (capital of Majapahit since Girindrawardhana – Brawijaya VI) by Sultan Trenggana from Demak in 1527. The leader of this region is Arya Terung with the title Adipati Sengguruh. The name Sengguruh is said to be related to the existence of an education center and the residence of the knights or banner (commonly called Kepanjian or Kepanjen area). The banners who want to study in Kepanjen are said to be saying "Let's go to the Teacher" which refers to the place where they study. These words gradually became Sengguruh. According to Babad ing Gresik (Chronicles of Gresik), the kingdom had tried to attack the Lamongan and Giri (Gresik) areas in 1535. However, the efforts of Arya Terung were unsuccessful, if not failed to maintain their occupation of the two regions. In fact, according to the records in Tedhak Dermayudan, after the failure of the conquest, Arya Terung adopted Islam and spread Islamic teachings throughout Sengguruh. As a result, the Majapahit sympathizers led by Raden Pramana rebelled and made the Arya Terung flee north around the lower reaches of the Brantas River.
