Cuban Missile Crisis Cuban Missile Crisis is a term that denotes the confrontation between the two superpowers i.e., the USA and the USSR.
The Soviet Union led by the Nikita Khrushchev installed nuclear missiles in Cuba in the hope of converting Cuba into a Russian base. The main aim was to plan a devastating attack on the USA if they start a war. This installation of nuclear missiles threatened a number of cities of the American mainland. It was because they were set on the target of those missiles. As a result, the US President, John F. Kennedy and his advisors ordered the American warships to intercept any Soviet ships heading to Cuba so as to avoid a full-scale nuclear war. At this step of the USA, Russian President ordered Warships to headed towards Cuba. This series of tensions and confrontation between the United States and the Soviet Union is known as the 'Cuban Missile Crisis' which later came to be known as an event of  'Cold War'.
Two world leaders who played a crucial role in the Cuban Missile Crisis were Nikita Khrushchev and John F Kennedy. This crisis could be avoided with the help of the UN.

It was a confrontation between the United States and the Soviet Union in 1962 over the presence of missile sites in Cuba; one of the “hottest” periods of the cold war.

Archaeologist reconstructs the past by a study of the artefacts which they unearth such as stamps, coins, remains of buildings, clay, pots or burnt grains. Archaeologists excavate ancient sites. They try to find out about the lifespan of people by studying various unearthed artefacts such as- remains of houses, pots, jewellery, coins, agricultural tools, weighs etc. Archaeologists also try to find about the social or economic difference by studying the graves of people. If the burial consists of pottery and ornaments, it indicates that people during that time believed in after life. 

Mosque is regarded as the basis of Islamic religious life. It has an open compound and pillars on all sides. The roof stands on all these pillars. In the middle of the compound, there is a pond, which is artificially made. Here, devotees can take bath or wash themselves before offering Namaz. Some special architectural features of Mosque are:

1. Mosque has orientation towards Mecca. It makes evident in the placement of the mihrab (prayer niche) and the minbar (pulpit).
2. Mosque blends a universal faith with local traditions. In Kerala, we find the shikhara like roof and in Bangladesh, we find dome like roof. In Kashmir we find the Shah Hamadan mosque which is the best example of Kashmiri wooden architecture, decorated with paper mache.

The economic history of India is the story of India's evolution from a largely agricultural and trading society to a mixed economy of manufacturing and services while the majority still survives on agriculture. Prior to 1947 that history encompasses the economy of the Indian subcontinent, corresponding to the modern nations of India, Pakistan, Nepal, Sri Lanka, and Bangladesh.

This history begins with the Indus Valley Civilization (3300–1300 BC), whose economy appears to have depended significantly on trade. Around 600 BC, the Mahajanapadas minted punch-marked silver coins. The period was marked by intensive trade activity and urban development. By 300 BC, the Maurya Empire had united most of the Indian subcontinent. The resulting political unity and military security allowed for a common economic system and enhanced trade and commerce, with increased agricultural productivity.

The Maurya Empire was followed by classical and early medieval kingdoms, including the Cholas, Guptas, Western Gangas, Harsha, Palas, Rashtrakutas and Hoysalas. During this period, Between 1 CE and 1000 CE, the Indian subcontinent is estimated to have accounted for one-third, to one-fourth of the world's population, and product, though GDP per capita was stagnant. India experienced per capita GDP growth in the high medieval era after 1000, during the Delhi Sultanate, but was not as productive as 15th century Ming China. After most of the subcontinent was reunited under the Mughal Empire, the empire became the largest economy by 1700, producing about a quarter of global GDP, before fragmenting, and being conquered over the century.[1][2] According to the Balance of Economic Power, India had the largest and most advanced economy for most of the interval between the 1st century and 18th century, the most of any region for a large part of the last two millennia.[3]

During the Mughal Empire, India was the world leader in manufacturing, producing 25% of the world's industrial output up until the mid-18th century, prior to British rule.
