Ganges Delta in the context of "Ganges"

The 1970 Bhola cyclone (also known as the Great Cyclone of 1970 or simply the Bhola Cyclone) was the deadliest tropical cyclone on record, as well as one of the deadliest humanitarian disasters ever recorded. It struck East Pakistan (present-day Bangladesh) and India's West Bengal on 12 November 1970. At least 300,000 people died in the storm, possibly as many as 500,000, primarily as a result of the storm surge that flooded much of the low-lying islands of the Ganges Delta. The Bhola cyclone was the sixth and strongest cyclonic storm of the 1970 North Indian Ocean cyclone season.

The cyclone formed over the central Bay of Bengal on 8 November and traveled northward, intensifying as it did so. It reached its peak with winds of 185 km/h (115 mph) on 10 November, and made landfall on the coast of East Pakistan on the following afternoon. The storm surge devastated many of the offshore islands, wiping out villages and destroying crops throughout the region. In the most severely affected upazila Tazumuddin, over 45% of the population of 167,000 were killed by the storm.

The 1970s (pronounced "nineteen-seventies"; commonly shortened to the "Seventies" or the "'70s") was the decade that began on January 1, 1970, and ended on December 31, 1979.

In the 21st century, historians have increasingly portrayed the 1970s as a "pivot of change" in world history, focusing especially on the economic upheavals that followed the end of the postwar economic boom. On a global scale, it was characterized by frequent coups, domestic conflicts and civil wars, and various political upheavals and armed conflicts which arose from or were related to decolonization, and the global struggle between NATO, the Warsaw Pact, and the Non-Aligned Movement. Many regions had periods of high-intensity conflict, notably Southeast Asia, the Middle East, Latin America, and Africa.

The Brahmaputra is a trans-boundary river which flows through Southwestern China, Northeastern India, and Bangladesh. It is known as the Brahmaputra or Luit in Assamese, Yarlung Tsangpo in Tibetan, the Siang/Dihang River in Arunachali, and Jamuna River in East Bengal. By itself, it is the 9th largest river in the world by discharge, and the 15th longest.

It originates in the Manasarovar Lake region, near Mount Kailash, on the northern side of the Himalayas in Burang County of Tibet where it is known as the Yarlung Tsangpo River. The Brahmaputra flows along southern Tibet to break through the Himalayas in great gorges (including the Yarlung Tsangpo Grand Canyon) and into Arunachal Pradesh. It enters India near the village of Gelling in Arunachal Pradesh and flows southwest through the Assam Valley as the Brahmaputra and south through Bangladesh as the Jamuna (not to be confused with the Yamuna of India). In the vast Ganges Delta, it merges with the Ganges, popularly known as the Padma in Bangladesh, and becomes the Meghna and ultimately empties into the Bay of Bengal.

The Meghna (Bengali: মেঘনা, romanized: Mēghnā) is one of the major rivers in Bangladesh, one of the three that form the Ganges Delta, the largest delta on earth, which fans out to the Bay of Bengal. A part of the Surma-Meghna River System, the Meghna is formed inside Bangladesh in Kishoreganj District above the town of Bhairab Bazar by the joining of the Surma and the Kushiyara, both of which originate in the hilly regions of eastern India as the Barak River. The Meghna meets its major tributary, the Padma, in Chandpur District. Other major tributaries of the Meghna include the Dhaleshwari, the Gumti, and the Feni. The Meghna empties into the Bay of Bengal in Bhola District via four principal mouths, named Tetulia (Ilsha), Shahbazpur, Hatia, and Bamni.

Dhaka (/ˈdɑːkə/ DAH-kə or /ˈdækə/ DAK-ə; Bengali: ঢাকা, romanized: Ḍhākā, pronounced [ˈɖʱaka] ), formerly spelled as Dacca, is the capital and largest city of Bangladesh. With an estimated population of 36.6 million, Dhaka is the second largest city by population in the world, and is widely considered to be the most densely populated built-up urban area in the world. Dhaka is an important cultural, economic, and scientific hub of Eastern South Asia. Dhaka ranks fourth in South Asia and 55th in the world in terms of GDP. Lying on the Ganges Delta, it is bounded by the Buriganga, Turag, Dhaleshwari and Shitalakshya rivers. It is also the largest Bengali-speaking city in the world.

The area of Dhaka has been inhabited since the first millennium. An early modern city developed from the 17th century as a provincial capital and commercial centre of the Mughal Empire. Dhaka was the capital of a proto-industrialized Mughal Bengal for 75 years (1608–39 and 1660–1704). It was the hub of the muslin trade in Bengal and one of the most prosperous cities in the world. The Mughal city was named Jahangirnagar (The City of Jahangir) in honour of the erstwhile ruling emperor Jahangir. The city's wealthy Mughal elite included princes and the sons of Mughal emperors. The pre-colonial city's glory peaked in the 17th and 18th centuries, when it was home to merchants from across Eurasia. The Port of Dhaka was a major trading hub for both riverine and maritime commerce. The Mughals decorated the city with well-laid gardens, tombs, mosques, palaces, and forts. The city was once called the Venice of the East.

Eastern South Asia is a subregion of South Asia. It includes the countries of Bangladesh, Bhutan, India (specifically East India and Northeast India), and Nepal. Geographically, it lies between the Eastern Himalayas and the Bay of Bengal. Two of the world's largest rivers, the Ganges and the Brahmaputra, flow into the sea through Eastern South Asia. The region includes the world's highest mountainous terrain and the world's largest delta, and has a climate ranging from alpine and subalpine to subtropical and tropical. Since Nepal, Bhutan, and northeast India are landlocked, the coastlines of Bangladesh and East India serve as the principal gateways to the region.

With more than 441 million inhabitants, Eastern South Asia is home to 6% of the world's population and 25% of South Asia's population. The Bangladesh, Bhutan, India, Nepal Initiative promotes economic integration in the region. The four countries are members of the South Asian Association for Regional Cooperation and the Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation. Yunnan Province and the Tibet Autonomous Region of the People's Republic of China (PRC) and Myanmar are historically, economically, and culturally interdependent on Eastern South Asia. The Bangladesh–China–India–Myanmar Forum has established an economic corridor in the region.
