of Jalaluddin Muhammad Shah. According to traditional Arakanese history, Arakan became a tributary state of Bengal and its kings adopted Muslim titles to fashion themselves after Bengali Sultans. Arakan later shrugged off Bengali hegemony and restored full independence. It later invaded southeastern Bengal several times, sometimes with success and sometimes unsuccessfully. Arakan continued to mint its coins following the model of Bengali tanka for 300 years, even after the dissolution of the Bengal Sultanate. A total of 16 Arakanese kings used Muslim titles. Arakan forcefully deported thousands of Bengali Muslims and Hindus during its invasions and collusion with the Portuguese. Deportees included the poet Alaol. As a result, the Bengali minority in Arakan developed a distinct Arakanese identity and became influential elites in Arakanese society. Arakanese Muslims, known today as Rohingya people, trace their ancestry to the period of Bengali influence in Arakan. The Bengal Sultanate also counted Tripura as a vassal state. Bengal restored the throne of Tripura by helping Ratna Manikya I to assume the throne. The Bengal Sultanate controlled Odisha at various points since the reign of Ilyas Shah. During the reign of Alauddin Hussain Shah, Bengal became an expanding regional empire. Under Hussain Shah, Bengali territory covered Arakan, Assam, Tripura, Orissa, Bihar and Jaunpur. Hussain Shah minted coins with the proclamation "conqueror of Kamrupa, Kamata, Jajnagar and Orissa". The Pratapgarh Kingdom came under Bengali suzerainty. The island of Chandradwip was annexed by the Hussain Shahi dynasty. In 1498, the Hussain Shahi dynasty dispatched military general Shah Ismail Ghazi with an army of 24,000 soldiers and a naval flotilla to conquer Assam. The Bengal forces overthrew the Khen dynasty. Prince Daniyal, a son of the Sultan, was appointed governor of Assam. Bengali control of Assam extended into the Brahmaputra Valley and up to Hajo. Assamese Muslims can trace their history to the Bengal Sultanate's conquest. Maritime trade Bengali ships dominated the Bay of Bengal and were the largest ships in the Indian and Pacific oceans. A royal vessel from Bengal could accommodate three tribute missions- from Bengal, Brunei and Sumatra- and was evidently the only vessel capable of such a task. European travelers like Ludovico di Varthema, Duarte Barbosa and Tomé Pires wrote about the presence of a large number of wealthy Bengali merchants and shipowners in Malacca. The trade between Bengal and the Maldives, based on rice and cowry shells, was probably done on Arab-style baghlah
