Bangladesh, Grenada and Guinea-Bissau join the United Nations.

Grenada ( (listen) gr-NAY-d; Grenadian Creole French: Gwenad ) is an island country in the West Indies in the Caribbean Sea at the southern end of the Grenadines island chain. Grenada consists of the island of Grenada itself, two smaller islands, Carriacou and Petite Martinique, and several small islands which lie to the north of the main island and are a part of the Grenadines. It is located northwest of Trinidad and Tobago, northeast of Venezuela and southwest of Saint Vincent and the Grenadines. Its size is 348.5 square kilometres (134.6 sq mi), and it had an estimated population of 112,523 in July 2020. Its capital is St. George's. Grenada is also known as the "Island of Spice" due to its production of nutmeg and mace crops.

Before the arrival of Europeans in the Americas, Grenada was inhabited by the indigenous peoples from South America. Christopher Columbus sighted Grenada in 1498 during his third voyage to the Americas. Following several unsuccessful attempts by Europeans to colonise the island due to resistance from resident Island Caribs, French settlement and colonisation began in 1649 and continued for the next century. On 10 February 1763, Grenada was ceded to the British under the Treaty of Paris. British rule continued until 1974 (except for a brief French takeover between 1779 and 1783). However, on 3 March 1967, it was granted full autonomy over its internal affairs as an Associated State, and from 1958 to 1962 Grenada was part of the Federation of the West Indies, a short-lived federation of British West Indian colonies.

Independence was granted on 7 February 1974 under the leadership of Eric Gairy, who became the first prime minister of Grenada of the sovereign state. The new country became a member of the Commonwealth of nations, with Queen Elizabeth II as head of state and is currently headed by King Charles III, King of Grenada. In March 1979, the MarxistLeninist New Jewel Movement overthrew Gairy's government in a bloodless coup d'tat and established the People's Revolutionary Government (PRG), headed by Maurice Bishop as prime minister. Bishop was later arrested and executed by members of the People's Revolutionary Army (PRA), prompting a U.S.-led invasion in October 1983. Since then, the island has returned to a parliamentary representative democracy and has remained politically stable.

Bangladesh (; Bengali: বাংলাদেশ, pronounced [ˈbaŋlaˌdeʃ] (listen)), officially the People's Republic of Bangladesh, is a country in South Asia. It is the eighth-most populous country in the world, with a population exceeding 163 million people in an area of either 148,460 square kilometres (57,320 sq mi) or 147,570 square kilometres (56,980 sq mi), making it one of the most densely populated countries in the world. Bangladesh shares land borders with India to the west, north, and east, and Myanmar to the southeast; to the south it has a coastline along the Bay of Bengal. It is narrowly separated from Nepal and Bhutan by the Siliguri Corridor; and from China by 100 km of the Indian state of Sikkim in the north. Dhaka, the capital and largest city, is the nation's economic, political, and cultural hub. Chittagong, the largest seaport, is the second-largest city. The official language is Bengali, one of the most eastern branches of the Indo-European language family.

Bangladesh forms the sovereign part of the historic and ethnolinguistic region of Bengal, which was divided during the Partition of British India in 1947. The country has a Bengali Muslim majority. Ancient Bengal was an important cultural center in the Indian subcontinent as the home of the states of Vanga, Pundra, Gangaridai, Gauda, Samatata, and Harikela. The Mauryan, Gupta, Pala, Sena, Chandra and Deva dynasties were the last pre-Islamic rulers of Bengal. The Muslim conquest of Bengal began in 1204 when Bakhtiar Khalji overran northern Bengal and invaded Tibet. Becoming part of the Delhi Sultanate, three city-states emerged in the 14th century with much of eastern Bengal being ruled from Sonargaon. Sufi missionary leaders like Sultan Balkhi, Shah Jalal and Shah Makhdum Rupos helped in spreading Muslim rule. The region was unified into an independent, unitary Bengal Sultanate. Under Mughal rule, eastern Bengal continued to prosper as the melting pot of Muslims in the eastern subcontinent and attracted traders from around the world. Mughal Bengal became increasingly assertive and independent under the Nawabs of Bengal in the 18th century. In 1757, the betrayal of Mir Jafar resulted in the defeat of Nawab Siraj-ud-Daulah to the British East India Company and eventual British dominance across South Asia. The Bengal Presidency grew into the largest administrative unit in British India. The creation of Eastern Bengal and Assam in 1905 set a precedent for the emergence of Bangladesh. In 1940, the first Prime Minister of Bengal supported the Lahore Resolution with the hope of creating a state in eastern South Asia. Prior to the partition of Bengal, the Prime Minister of Bengal proposed a Bengali sovereign state. A referendum and the announcement of the Radcliffe Line established the present-day territorial boundary of Bangladesh.

In 1947, East Bengal became the most populous province in the Dominion of Pakistan. It was renamed as East Pakistan with Dhaka becoming the country's legislative capital. The Bengali Language Movement in 1952; the East Bengali legislative election, 1954; the 1958 Pakistani coup d'état; the Six point movement of 1966; and the 1970 Pakistani general election resulted in the rise of Bengali nationalism and pro-democracy movements in East Pakistan. The refusal of the Pakistani military junta to transfer power to the Awami League led by Sheikh Mujibur Rahman led to the Bangladesh Liberation War in 1971, in which the Mukti Bahini aided by India waged a successful armed revolution. The conflict saw the 1971 Bangladesh genocide and the massacre of pro-independence Bengali civilians, including intellectuals. The new state of Bangladesh became the first constitutionally secular state in South Asia in 1972. Islam was declared the state religion in 1988. In 2010, the Bangladesh Supreme Court reaffirmed secular principles in the constitution.Bangladesh is a unitary parliamentary constitutional republic based on the Westminster system. Bengalis make up 98% of the total population of Bangladesh, and the large Muslim population of Bangladesh makes it the third-largest Muslim-majority country. The country consists of eight divisions, 64 districts and 495 subdistricts. It maintains the third-largest military in South Asia after India and Pakistan; and has been a major contributor to UN peacekeeping operations. A middle power in the Indo-Pacific, Bangladesh is an emerging economy ranked as the 33rd-largest in the world by nominal GDP, and the 29th-largest by PPP. It hosts one of the largest refugee populations in the world due to the Rohingya genocide. Bangladesh faces many challenges, including the adverse effects of climate change, poverty, illiteracy, corruption, authoritarianism and human rights abuses. However, the poverty rate has halved since 2011 and the country is expected to become a middle income country in this decade. Once a historic center of the muslin cloth trade, Bangladesh is now one of the world's largest modern garment exporters.
