History of Bengal
–
The history of Bengal includes modern-day Bangladesh and West Bengal in the eastern part of the Indian subcontinent, at the apex of the Bay of Bengal and dominated by the fertile Ganges delta. The advancement of civilization in Bengal dates back four millennia, the region was known to the ancient Greeks and Romans as Gangaridai. The Ganges and the Brahmaputra rivers act as a marker of the region. Bengal, at times, has played an important role in the history of the Indian subcontinent, the areas early history featured a succession of Indian empires, internal squabbling, and a tussle between Hinduism and Buddhism for dominance. Ancient Bengal was the site of several major Janapadas, while the earliest cities date back to the Vedic period, the region was part of several ancient pan-Indian empires, including the Mauryans and Guptas. It was also a bastion of regional kingdoms, the citadel of Gauda served as capital of the Gauda Kingdom, the Buddhist Pala Empire and Hindu Sena Empire. This era saw the development of Bengali language, script, literature, music, art, from the 13th century onward, the region was controlled by the Bengal Sultanate, Hindu Rajas, and Baro-Bhuyan landlords. In the late 16th and early 17th centuries, Isa Khan, a Muslim Rajput chief, afterwards, the region came under the suzerainty of the Mughal Empire. Under the Mughals, Bengal Subah generated 50% of the empires GDP, the gradual decline of the Mughals led to quasi-independent state under the Nawabs of Bengal, subsequent Maratha expeditions in Bengal, and finally the conquest by the British East India Company. The British took control of the region from the late 18th century, the company consolidated their hold on the region following the Battle of Plassey in 1757 and Battle of Buxar in 1764 and by 1793 took complete control of the region. Kolkata served for years as the capital of British controlled territories in India. The exact origin of the word Bangla is unknown, though it is believed to be derived from the Dravidian-speaking tribe Bang/Banga that settled in the area around the year 1000 BCE. Other accounts speculate that the name is derived from Venga, which came from the Austric word Bonga meaning the Sun-god, according to the Mahabharata, a number of Puranas and the Harivamsha Vanga was one of the adopted sons of King Vali who founded the Vanga Kingdom. It was either under Magadh or under Kalinga Rules except few years under Pals. The Muslim accounts refer that Bong, the earliest reference to Vangala has been traced in the Nesari plates of Rashtrakuta Govinda III which speak of Dharmapala as the king of Vangala. The records of Rajendra Chola I of the Chola dynasty, who invaded Bengal in the 11th century, shams-ud-din Ilyas Shah took the title Shah-e-Bangla and united the whole region under one government. An interesting theory of the origin of the name is provided by Abul-Fazl in his Ain-i-Akbari, from this suffix added to the Bung, the name Bengal arose and gained currency Stone Age tools dating back 20,000 years have been excavated in the state. Remnants of Copper Age settlements in the Bengal region date back 4,000 years, the original settlers spoke non-Aryan languages— they may have spoken Austric or Austro-Asiatic languages like the languages of the present-day Kola, Bhil, Santhal, Shabara, and Pulinda people. At a subsequent age, peoples speaking languages from two other language families— Dravidian and Tibeto-Burman—seem to have settled in Bengal, archaeological discoveries during the 1960s furnished evidence of a degree of civilisation in certain parts of Bengal as far back as the first millennium BC

Gangaridai
–
Gangaridai was an ancient region corresponding to the Ganges delta region of the Indian subcontinent, which was mentioned in the records of numerous Greco-Roman writers. The term means nation of the Ganges in Greek and Latin and it is one of the earliest references to the Bengal region in the Indian subcontinent. According to ancient Indian records, the Vanga Kingdom and Samatata Kingdom occupied the region during the same period, the capital of the Gangaridai was situated at Kotalipara in present-day Gopalganj District, Bangladesh. The region was described as a kingdom with one of the largest cavalries of chariots and it was described by the Greek traveller Megasthenes in his work Indica. Greek and Roman historians suggested that Alexander the Great withdrew from the Indian subcontinent, anticipating a counterattack from an alliance of Gangaridai, later writers noted merchant shipping links between Gangaridais cities and Roman Egypt. Ptolemy, wrote that the Gangaridai occupied the region about the five mouths of the Ganges. The five mouths were the Kambyson, the Mega, the Kamberikhon, the Pseudostomon and these rivers may refer to the Meghna, Padma, Jamuna, Karnaphuli and Rupsa. Ptolemy also noted a natural harbour in the Chittagong coastline. Quoted from The Classical Accounts of India, Dr R. C, quoted from Ancient India as Described in Classical Literature, John W. McCrindle, p.201. Quoted from The Classical Accounts of India, p. 103-128, plutarch noted both Gangaridae and Prasii together, The Battle with Porus depressed the spirits of the Macedonians, and made them very unwilling to advance farther into India. This river, they heard, had a breadth of two and thirty stadia, and a depth of 1000 fathoms, while its banks were covered all over with armed men, horses. For the kings of the Gandaritai and the Prasiai were reported to be waiting for him with an army of 80,000 horse,200,000 foot,8,000 war-chariots, quoted from The Classical Accounts of India, p.198. Owing to this, their country has never been conquered by any king, for all other nations dread the overwhelming number. Quoted from the Epitome of Megasthenes, Indika, Ancient India as Described by Megasthenes and Arrian. Translated and edited by J. W. McCrindle, pliny the Elder wrote about the people, In the final part of its Ganges course, which is through the country of the Gangarides. In the parts which lie southward from the Ganges the inhabitants, already swarthy, are coloured by the sun. Quoted from The Classical Accounts of India, Dr. R. C, Megasthenes wrote about the people known as Gangarides, The least breadth of the Ganges is eight miles, and its greatest twenty. Its depth where it is shallowest is fully a hundred feet, the people who live in the furthest-off part are the Gangarides, whose king possesses 1,000 horse,700 elephants, and 60,000 foot in apparatus of war

Maurya Empire
–
The Maurya Empire was a geographically extensive Iron Age historical power founded by Chandragupta Maurya which dominated ancient India between c. 322 and 187 BCE. Originating from the kingdom of Magadha in the Indo-Gangetic Plain in the side of the Indian subcontinent. The empire was the largest to have existed in the Indian subcontinent. By 316 BCE the empire had fully occupied Northwestern India, defeating and conquering the satraps left by Alexander, Chandragupta then defeated the invasion led by Seleucus I, a Macedonian general from Alexanders army, gaining additional territory west of the Indus River. The Maurya Empire was one of the largest empires of the world in its time and it declined for about 50 years after Ashokas rule ended, and it dissolved in 185 BCE with the foundation of the Shunga dynasty in Magadha. After the Kalinga War, the Empire experienced nearly half a century of peace, Mauryan India also enjoyed an era of social harmony, religious transformation, and expansion of the sciences and of knowledge. Ashoka sponsored the spreading of Buddhist ideals into Sri Lanka, Southeast Asia, West Asia, the population of the empire has been estimated to be about 50–60 million, making the Mauryan Empire one of the most populous empires of Antiquity. Archaeologically, the period of Mauryan rule in South Asia falls into the era of Northern Black Polished Ware, the Arthashastra and the Edicts of Ashoka are the primary sources of written records of Mauryan times. The Lion Capital of Ashoka at Sarnath has been made the national emblem of India, the Maurya Empire was founded by Chandragupta Maurya, with help from Chanakya, at Takshashila. Chanakya swore revenge and vowed to destroy the Nanda Empire, meanwhile, the conquering armies of Alexander the Great refused to cross the Beas River and advance further eastward, deterred by the prospect of battling Magadha. Alexander returned to Babylon and re-deployed most of his troops west of the Indus River, soon after Alexander died in Babylon in 323 BCE, his empire fragmented, and local kings declared their independence, leaving several smaller disunited satraps. Chandragupta Mauryas rise to power is shrouded in mystery and controversy, on one hand, a number of ancient Indian accounts, such as the drama Mudrarakshasa by Vishakhadatta, describe his royal ancestry and even link him with the Nanda family. A kshatriya clan known as the Mauryas are referred to in the earliest Buddhist texts, however, any conclusions are hard to make without further historical evidence. Chandragupta first emerges in Greek accounts as Sandrokottos, as a young man he is said to have met Alexander. He is also said to have met the Nanda king, angered him, Chanakyas original intentions were to train a guerilla army under Chandraguptas command. The Mudrarakshasa of Vishakhadatta as well as the Jaina work Parishishtaparvan talk of Chandraguptas alliance with the Himalayan king Parvatka, Chanakya encouraged Chandragupta Maurya and his army to take over the throne of Magadha. These men included the general of Taxila, accomplished students of Chanakya, the representative of King Porus of Kakayee, his son Malayketu. The Macedonians may then have participated, together with other groups, the Mudrarakshasa of Visakhadutta as well as the Jaina work Parisishtaparvan talk of Chandraguptas alliance with the Himalayan king Parvatka, often identified with Porus

Shunga Empire
–
The Shunga Empire was an ancient Indian dynasty from Magadha that controlled vast areas of the Indian subcontinent from around 187 to 78 BCE. The dynasty was established by Pushyamitra Shunga, after the fall of the Maurya Empire and its capital was Pataliputra, but later emperors such as Bhagabhadra also held court at Besnagar in eastern Malwa. Pushyamitra Shunga ruled for 36 years and was succeeded by his son Agnimitra, the empire is noted for its numerous wars with both foreign and indigenous powers. They fought the Kalinga, the Satavahana dynasty, the Indo-Greek Kingdom, Shunga rulers helped to establish the tradition of royal sponsorship of learning and art. The script used by the empire was a variant of Brahmi script and was used to write Sanskrit, the Shunga Empire played an imperative role in patronizing culture at a time when some of the most important developments in Hindu thought were taking place. Patanjalis Mahābhāṣya was composed in this period, artistry also progressed with the rise of the Mathura art style. The Kanva dynasty succeeded the Shungas around 73 BCE, Pushyamitra Shunga then ascended the throne. Pushyamitra Shunga became the ruler of Magadha and neighbouring territories, the empire of Pushyamitra was extended to the Narmada River in the south, controlled Jalandhar and Sialkot in the Punjab region in the northwest and the city of Ujjain in Central India. Kabul and much of the Punjab passed into the hands of the Indo-Greeks, Pushyamitra died after ruling for 36 years. He was succeeded by son Agnimitra and this prince is the hero of a famous drama by one of Indias greatest playwrights, Kālidāsa. Agnimitra was viceroy of Vidisha when the story takes place, the power of the Shungas gradually weakened. It is said there were ten Shunga emperors. The Shungas were succeeded by the Kanva dynasty around 73 BCE, buddhist scripture Divyavdan and ancient Tibbatan historian Taranath have written about persecution of Buddhists, However, there is doubt as to whether he did persecute Buddhists actively. Later Shunga emperors were seen as amenable to Buddhism and as having contributed to the building of the stupa at Bharhut, some writers believe that Brahmanism competed in political and spiritual realm with Buddhism in the Gangetic plains. Buddhism flourished in the realms of the Bactrian kings, some Indian scholars are of the opinion that the orthodox Shunga emperors were not intolerant towards Buddhism and that Buddhism prospered during the time of the Shunga emperors. The existence of Buddhism in Bengal in the Shunga period can also be inferred from a tablet that was found at Tamralipti and is on exhibit at the Asutosh Museum in Kolkata. An inscription at Bodh Gaya at the Mahabodhi Temple records the construction of the temple as follows, another inscription reads, The gift of Kurangi, the mother of living sons and the wife of Emperor Indragnimitra, son of Kosiki. The gift also of Srima of the palace shrine

Gupta Empire
–
The Gupta Empire was an ancient Indian empire founded by Sri Gupta. The empire existed at its zenith from approximately 320 to 550 CE, the peace and prosperity created under the leadership of the Guptas enabled the pursuit of scientific and artistic endeavors. Chandragupta I, Samudragupta, and Chandragupta II were the most notable rulers of the Gupta dynasty, the high points of the period is great cultural developments which took place during the reign of Chandragupta II. Science and political administration reached new heights during the Gupta era, strong trade ties also made the region an important cultural center and set the region up as a base that would influence nearby kingdoms and regions in Burma, Sri Lanka, and Southeast Asia. The earliest available Indian epics are also thought to have committed to written texts around this period. After the collapse of the Gupta Empire in the 6th century, a minor line of the Gupta clan continued to rule Magadha after the disintegration of the empire. These Guptas were ultimately ousted by Vardhana ruler Harsha, who established his empire in the first half of the 7th century, according to many historians, the Gupta dynasty was a Vaishya dynasty. Historian Ram Sharan Sharma asserts that the Vaishya Guptas appeared as a reaction against oppressive rulers, brannigan, the rise of the Gupta Empire was one of the most prominent violations of the caste system in ancient India. There is controversy among scholars about the homeland of the Guptas. Jayaswal has pointed out that the Guptas were originally inhabitants of Prayaga, Uttar Pradesh, in north India, another scholar, Gayal supported the theory of Jaiswal, suggesting that the original home of the Guptas was Antarvedi embracing the regions of Oudh and Prayag. However another historian of this time in Indian history, Ganguli, has offered a different view about the original Gupta homeland, according to him the Guptas homeland is further south, the Murshidabad region of Bengal, and not Magadha in Bihar. He based his theory on the statement of the Chinese Buddhist monk, Yijing, fleet and other historians however criticize Gangulis theory because Sri Gupta ruled during the end of the 3rd century, but Yijing placed him at the end of the 2nd century. Hence the theory of historians, who have provided their views based on the accounts of Yijing, are considered less valid than theories based on sources such as coinage. From these theories, several conflicting opinions about the original homeland, according to Allan and a few other scholars, the Guptas were initially concentrated in the region of Magadha and from there they extended their sway to Bengal. According to other groups, the homeland of the Guptas was Varendri or the Varendra Bhumi in Bengal. Whatever the theory is, the rule of the Guptas initiated the Golden Age in history of ancient India, bengali historians like HC Raychoudhuri the Guptas originated from the Varendri region which is now part of Rangpur and Rajshahi Division of modern-day Bangladesh. DC Ganguly, on the hand, considers the surrounding region of Murshidabad as the original home of the Guptas. The most likely time for the reign of Sri Gupta is c, the Murundas who were feudal lords of Kushans provided or granted land to Srigupta

Mallabhum
–
Mallabhum, also known as Mallabhoom was the kingdom ruled by the Malla kings of Bishnupur, primarily in the present Bankura district in Indias state of West Bengal. It is told that Mallabhum is the territory, which included Bankura, the Malla Rajas ruled over the vast territory in the south-western part of present West Bengal and a part of southeastern Jharkhand. The area around Bishnupur was called Mallabhum, the core area would cover present day Bankura police station area, Onda, Bishnupur, Kotulpur and Indas. In olden days the term was used for a larger area. In the north it stretched from Damin-i-koh in Santhal Parganas to Midnapore in the south and it included the eastern part of Bardhaman and included parts of Chota Nagpur in the west. According to OMalley, the Rajas of Bishnupur were also known as Malla kings, Malla is a Sanskrit word meaning wrestler but there could be some links with the Mal tribes of the area, who had intimate connection with the Bagdis. From around 7th century AD till around the advent of British rule, for around a millennium, history of Bankura district is identical with the rise, the legends of Bipodtarini Devi are associated with Malla Kings of Bishnupur. According to Bhattacharjee, Tarun Dev during Malla period, the society was centred round the village. The tax collectors were called as Gomostha and their assistants as Aat Pahari or Paik The Mukhiya or Mandal was the title of headman, Malla kings had several service groups. Due to scarcity of money, the Malla kings used to present land instead of salary to all these service groups. This type of land is again of two types – namely the Panchaki jamin or land with a tax and another one is the Bepanchaki jamin or land without any tax. Mallas started their own calendar that is Malla era and it is told that Malla era started from Indra Dwadasi day in the year 102 Bengali calendar of the month Bhadro. According to Dr. Bir Singha Dev also had the seven big lakes or tanks, called Lalbandh, Krishnabandh, Gantatbandh, Jamunabandh, Kalindibandh, Shyambandh, and pokabandh excavated, and erected.

Pala Empire
–
The Pala Empire was an imperial power during the Late Classical period on the Indian subcontinent, which originated in the region of Bengal. It is named after its ruling dynasty, whose rulers bore names ending with the suffix of Pala and they were followers of the Mahayana and Tantric schools of Buddhism. The empire was founded with the election of Gopala as the emperor of Gauda in 750 CE, the Pala stronghold was located in Bengal and Bihar, which included the major cities of Vikrampura, Pataliputra, Gauda, Monghyr, Somapura, Ramvati, Tamralipta and Jaggadala. The Palas were astute diplomats and military conquerors and their army was noted for its vast war elephant cavalry. Their navy performed both mercantile and defensive roles in the Bay of Bengal, the Palas were important promoters of classical Indian philosophy, literature, painting and sculpture. They built grand temples and monasteries, including the Somapura Mahavihara, the Proto-Bengali language developed under Pala rule. The empire enjoyed relations with the Srivijaya Empire, the Tibetan Empire, islam first appeared in Bengal during Pala rule, as a result of increased trade between Bengal and the Middle East. Abbasid coinage found in Pala archaeological sites, as well as records of Arab historians, point to flourishing mercantile, the House of Wisdom in Baghdad absorbed the mathematical and astronomical achievements of Indian civilisation during this period. The empire reached its peak under Emperors Dharmapala and Devapala, the Palas also exerted a strong cultural influence under Atisa in Tibet, as well as in Southeast Asia. Pala control of North India was ultimately ephemeral, as they struggled with the Gurjara-Pratiharas, after a short lived decline, Emperor Mahipala I defended imperial bastions in Bengal and Bihar against South Indian Chola invasions. Emperor Ramapala was the last strong Pala ruler, who gained control of Kamarupa, the empire was considerably weakened by the 11th century, with many areas engulfed in rebellion. The resurgent Hindu Sena dynasty dethroned the Pala Empire in the 12th century, the Pala period is considered one of the golden eras of Bengali history. The Palas brought stability and prosperity to Bengal after centuries of war between warring divisions. They advanced the achievements of previous Bengali civilisations and created outstanding works of art and they laid the basis for the Bengali language, including its first literary work, the Charyapada. The Pala legacy is reflected in Tibetan Buddhism. According to the Khalimpur copper plate inscription, the first Pala king Gopala was the son of a warrior named Vapyata, the Ramacharitam attests that Varendra was the fatherland of the Palas. The ethnic origins of the dynasty are unknown, although the later claim that Gopala was a Kshatriya belonging to the legendary solar dynasty. The Ballala-Carita states that the Palas were Kshatriyas, a claim reiterated by Taranatha in his History of Buddhism in India as well as Ghanaram Chakrabarty in his Dharmamangala, the Ramacharitam also attests the fifteenth Pala emperor, Ramapala, as a Kshatriya

Chola dynasty
–
The Chola dynasty was one of the longest-ruling dynasties in the history of southern India. The earliest datable references to this Tamil dynasty are in inscriptions from the 3rd century BCE left by Ashoka, as one of the Three Crowned Kings of Tamilakam, the dynasty continued to govern over varying territory until the 13th century CE. The whole country south of the Tungabhadra was united and held as one state for a period of two centuries and more, the Chola fleet represented the zenith of ancient Indian sea power. During the period 1010–1200, the Chola territories stretched from the islands of the Maldives in the south to as far north as the banks of the Godavari River in Andhra Pradesh. Rajaraja Chola conquered peninsular South India, annexed parts of which is now Sri Lanka, Rajendra Chola sent a victorious expedition to North India that touched the river Ganges and defeated the Pala ruler of Pataliputra, Mahipala. He also successfully invaded cities of Srivijaya of Malaysia and Indonesia, the Chola dynasty went into decline at the beginning of the 13th century with the rise of the Pandyan Dynasty, which ultimately caused their downfall. The Cholas left a lasting legacy and their patronage of Tamil literature and their zeal in the building of temples has resulted in some great works of Tamil literature and architecture. The Chola kings were avid builders and envisioned the temples in their kingdoms not only as places of worship and they pioneered a centralised form of government and established a disciplined bureaucracy. The Chola school of art spread to Southeast Asia and influenced the architecture, the Cholas are also known as the Choda. There is very little available in regarding their origin. Its antiquity is evident from the mentions in ancient Tamil literature, Later medieval Cholas also claimed a long and ancient lineage. Mentions in the early Sangam literature indicate that the earliest kings of the dynasty antedated 100 CE, Cholas were mentioned in Ashokan Edicts of 3rd Century BCE as one of the neighboring countries existing in the South. A commonly held view is that Chola is, like Chera and Pandya, the annotator Parimelazhagar said, The charity of people with ancient lineage are forever generous in spite of their reduced means. Other names in use for the Cholas are Killi, Valavan and Sembiyan. Killi perhaps comes from the Tamil kil meaning dig or cleave and this word often forms an integral part of early Chola names like Nedunkilli, Nalankilli and so on, but almost drops out of use in later times. Valavan is most probably connected with valam – fertility and means owner or ruler of a fertile country, in Tamil lexicon Chola means Soazhi or Saei denoting a newly formed kingdom, in the lines of Pandya or the old country. There is very little evidence available of the Cholas prior to the 7th century. Historic records exist thereafter, including inscriptions on temples, the main source for the available information of the early Cholas is the early Tamil literature of the Sangam Period

Delhi Sultanate
–
The Delhi Sultanate was a Muslim kingdom based mostly in Delhi that stretched over large parts of the Indian subcontinent for 320 years. Five dynasties ruled over Delhi Sultanate sequentially, the Mamluk dynasty, the Khilji dynasty, the Tughlaq dynasty, the Sayyid dynasty, the first four dynasties were of Turkic origin, and the last dynasty was of Afghan origin. Qutb-ud-din Aibak, a slave of Muhammad Ghori, was the first sultan of Delhi. Afterwards the Khilji dynasty was able to conquer most of central India. The sultanate reached the peak of its reach during the Tughlaq dynasty. This was followed by due to continuing Hindu-Muslim wars, states such as the Vijayanagara Empire asserting independence. The Delhi Sultanate caused destruction and desecration of politically important temples of South Asia, in 1526 the Sultanate fell, to be succeeded by the Mughal Empire. By 962 AD, Hindu and Buddhist kingdoms in South Asia were under a wave of raids from Muslim armies from Central Asia. Among them was Mahmud of Ghazni, who raided and plundered kingdoms in north India from east of the Indus river to west of Yamuna river seventeen times between 997 and 1030, Mahmud of Ghazni raided the treasuries but retracted each time, only extending Islamic rule into western Punjab. The wave of raids on north Indian and western Indian kingdoms by Muslim warlords continued after Mahmud of Ghazni, the raids did not establish or extend permanent boundaries of their Islamic kingdoms. The Ghurid Sultan Muizz al-Din Muhammad began a war of expansion into north India in 1173. He sought to carve out a principality for himself by expanding the Islamic world, Mu’izz sought a Sunni Islamic kingdom of his own extending east of the Indus river, and he thus laid the foundation for the Muslim kingdom called the Delhi Sultanate. Some historians chronicle the Delhi Sultanate from 1192 due to the presence, Muizz al-Din was assassinated in 1206, by Ismāʿīlī Shia Muslims in some accounts or by Hindu Khokhars in others. After the assassination, one of Mu’izz slaves, the Turkic Qutbu l-Din Aibak, assumed power, Qutb al-Din Aibak, a slave of Muizz ad-Din Muhammad Ghori, was the first ruler of the Delhi Sultanate. Aibak was of Cuman-Kipchak origin, and due to his lineage, Aibak reigned as the Sultan of Delhi for four years. After Aibak died, Aram Shah assumed power in 1210, but he was assassinated in 1211 by Shams-ud-din Iltutmish, iltutmishs power was precarious, and a number of Muslim amirs challenged his authority as they had been supporters of Qutb al-din Aibak. After a series of conquests and brutal executions of opposition, he consolidated his power and his rule was challenged a number of times, such as by Qubacha, and this led to a series of wars. Iltumish conquered Multan and Bengal from contesting Muslim rulers, as well as Ranathambhore and he also attacked, defeated, and executed Taj al-Din Yildiz, who asserted his rights as heir to Muizz ad-Din Muhammad Ghori

Bengal Sultanate
–
The Bengal Sultanate, officially the Sultanate of Bengal, was a Muslim state and empire based in the Indian subcontinent on the coast of the Bay of Bengal. It was an important power in South and Southeast Asia and its rulers carried the title of King of Kings in the East. The kingdoms heartland was in Bengal, which is divided between Bangladesh and the Indian state of West Bengal, but its realm included large parts of North India. Its bordering countries included the Delhi Sultanate, Tibet, Ahom, the Bengal Sultanate seceded from the Delhi Sultanate under Shamsuddin Ilyas Shah in 1352 and had capitals in Gaur, Pandua and Sonargaon. Delhi recognised Bengals independence after it was defeated by Ilyas Shah and his son, the kingdom enjoyed a strategic relationship with Ming China. It reached the height of its power during the reigns of Jalaluddin Muhammad Shah and Alauddin Hussain Shah in the 15th and early 16th centuries, Trade links were fostered with the Horn of Africa, the Maldives and Malacca. Its political economy featured the Taka as its standard currency, Bengali Muslim architecture flourished under the sultanates distinct regional genre, incorporating Bengali and Persian elements. A cosmopolitan literary culture developed in the kingdom, in the mid 16th century, Bengal was overrun by Sher Shah Suris conquests. Arakan ended its relationship with Bengal after allying with the Portuguese Empire. The Mughals defeated the last Sultan, Daud Khan Karrani, in Rajmahal in 1576, subsequently, eastern Bengal came under the control of the Baro-Bhuyan chieftains. By the 17th century, most of the territories of the sultanate were annexed by Mughal Bengal, Bengal was integrated into the Muslim world after the Islamic conquest of the Indian subcontinent. It was annexed by Bakhtiar Khilji as a province of the Delhi Sultanate, in the mid 14th century, governors in Bengal declared independence from the Delhi Sultanate, including at Lakhnauti, Sonargaon and Satgaon. In 1352, the Bengal Sultanate was formed by Shamsuddin Ilyas Shah after he conquered the three cities and he also defeated an invasion by the Sultan of Delhi Firuz Shah Tughluq in 1353. Ilyas Shah led successful campaigns against neighbouring Hindu states which consolidated the position of the Bengal Sultanate as the foremost military power in the eastern subcontinent, the records of medieval Indian historians, such as Abul Fazl, described him as first Shah of Bengal. His successors formed the Ilyas Shahi dynasty and his son Sikandar Shah and grandson Ghiyasuddin Azam Shah expanded the military, diplomatic and architectural influence of the sultanate. In 1414, Jalaluddin Muhammad Shah, the son of the Hindu zamindar Raja Ganesha, assumed the throne after a coup backed by his father and he reigned until 1433 and proclaimed himself as a caliph of Islam. During his reign, Arakan in Burma came under a century of Bengali suzerainty and his military assisted the Arakanese ruler Narameikhla to regain control of the city of Mrauk U in return for Arakan becoming a vassal state of the Bengal Sultanate. Bengali Muslims formed their own settlements in Arakan, the Buddhist rulers in Arakan received Islamic titles
