110-506: The House is a two-story, five-bay, Federal style building made of brick . It presently has ten interior rooms. When first built, there were only five rooms and a 20-foot-long (6.1 m) hall. These were three 20-by-20-foot (6.1 m × 6.1 m) rooms and hall on the first floor, and on the second floor a 60-by-20-foot (18.3 m × 6.1 m) ballroom and another 20-by-20-foot (6.1 m × 6.1 m) room. As there were still fears of attacks by Native Americans when

220-558: A Cold War episode resulting in East Pakistan 's secession, was the most recent instance of a new nation being formed in the region. South Asia has a total area of 5.2 million sq.km (2 million sq.mi), which is 10% of the Asian continent. The population of South Asia is estimated to be 2.04 billion or about one-fourth of the world's population, making it both the most populous and the most densely populated geographical region in

It

440-606: A colonial economy, but also consolidating its sovereignty . British Crown rule began in 1858. The rights promised to Indians were granted slowly, but technological changes were introduced, and modern ideas of education and the public life took root. In 1947 the British Indian Empire was partitioned into two independent dominions , a Hindu-majority Dominion of India and a Muslim-majority Dominion of Pakistan , amid large-scale loss of life and an unprecedented migration. The 1971 Bangladesh Liberation War ,

550-972: A dry, small aggregate concrete which is formed in steel moulds by vibration and compaction in either an "egglayer" or static machine. The finished blocks are cured, rather than fired, using low-pressure steam. Concrete bricks and blocks are manufactured in a wide range of shapes, sizes and face treatments – a number of which simulate the appearance of clay bricks. Concrete bricks are available in many colours and as an engineering brick made with sulfate-resisting Portland cement or equivalent. When made with adequate amount of cement they are suitable for harsh environments such as wet conditions and retaining walls. They are made to standards BS 6073, EN 771-3 or ASTM C55. Concrete bricks contract or shrink so they need movement joints every 5 to 6 metres, but are similar to other bricks of similar density in thermal and sound resistance and fire resistance. Compressed earth blocks are made mostly from slightly moistened local soils compressed with

660-696: A full 5-year term in office. India has grown significantly, having slashed its rate of extreme poverty to below 20% and surpassed Pakistan's GDP per capita in the 2010s due to economic liberalisation from the 1980s onward. Bangladesh, having struggled greatly for decades due to conflict with and economic exploitation by Pakistan, is now one of the fastest-growing countries in the region, beating India in terms of GDP per capita . Afghanistan has gone through several invasions and Islamist regimes, with many of its refugees having gone to Pakistan and other parts of South Asia and bringing back cultural influences such as cricket . Religious nationalism has grown across

770-443: A history older than fired bricks, and have an additional ingredient of a mechanical binder such as straw. Bricks are laid in courses and numerous patterns known as bonds , collectively known as brickwork , and may be laid in various kinds of mortar to hold the bricks together to make a durable structure. The earliest bricks were dried mudbricks , meaning that they were formed from clay-bearing earth or mud and dried (usually in

880-457: A kiln which makes them durable. Modern, fired, clay bricks are formed in one of three processes – soft mud, dry press, or extruded. Depending on the country, either the extruded or soft mud method is the most common, since they are the most economical. Clay and shale are the raw ingredients in the recipe for a fired brick. They are the product of thousands of years of decomposition and erosion of rocks, such as pegmatite and granite , leading to

990-708: A land mass which extends from the Himalayas into a portion of the basin under the Indian Ocean, including parts of South China and Eastern Indonesia , as well as Kunlun and Karakoram ranges, and extending up to but not including Ladakh , Kohistan , the Hindu Kush range, and Balochistan .

There are thousands of types of bricks that are named for their use, size, forming method, origin, quality, texture, and/or materials. Categorized by manufacture method: South Asia South Asia is the southern subregion of Asia , which

1430-792: A principality for himself by expanding the Islamic world, and thus laid the foundation for the Muslim kingdom that became the Delhi Sultanate . Some historians chronicle the Delhi Sultanate from 1192 due to the presence and geographical claims of Mu'izz al-Din in South Asia by that time. The Delhi Sultanate covered varying parts of South Asia and was ruled by a series of dynasties: Mamluk, Khalji, Tughlaq, Sayyid, and Lodi dynasties. Muhammad bin Tughlaq came to power in 1325, launched

1540-483: A relatively low embodied energy and carbon footprint . The ingredients are first harvested and added together, with clay content ranging from 30% to 70%. The mixture is broken up with hoes or adzes , and stirred with water to form a homogenous blend. Next, the tempers and binding agents are added in a ratio, roughly one part straw to five parts earth to reduce weight and reinforce the brick by helping reduce shrinkage. However, additional clay could be added to reduce

1650-460: A scholar of political science at Carleton University , the terms South Asia, Southwest Asia, and Central Asia are distinct, but the confusion and disagreements have arisen due to the geopolitical movement to enlarge these regions into Greater South Asia, Greater Southwest Asia , and Greater Central Asia . The frontier of Greater South Asia, states Cutler, between 2001 and 2006 has been geopolitically extended to eastern Iran and western Afghanistan in

1760-601: A war of expansion and the Delhi Sultanate reached it largest geographical reach over the South Asian region during his 26-year rule. A Sunni Sultan, Muhammad bin Tughlaq persecuted non-Muslims such as Hindus, as well as non-Sunni Muslims such as Shia and Mahdi sects. Revolts against the Delhi Sultanate sprang up in many parts of South Asia during the 14th century. In the northeast, the Bengal Sultanate became independent in 1346 CE. It remained in power through

1870-441: Is a similar term referring to a rectangular building unit composed of clay or concrete, but is usually larger than a brick. Lightweight bricks (also called lightweight blocks) are made from expanded clay aggregate . Fired bricks are one of the longest-lasting and strongest building materials , sometimes referred to as artificial stone, and have been used since c.  4000 BC . Air-dried bricks, also known as mudbricks , have

1980-876: Is common in Sweden as well as Russia and other post-Soviet countries, especially in houses built or renovated in the 1970s. A version known as fly ash bricks , manufactured using fly ash , lime, and gypsum (known as the FaL-G process) are common in South Asia. Calcium-silicate bricks are also manufactured in Canada and the United States, and meet the criteria set forth in ASTM C73 – 10 Standard Specification for Calcium Silicate Brick (Sand-Lime Brick). Bricks formed from concrete are usually termed as blocks or concrete masonry unit , and are typically pale grey. They are made from

2090-522: Is defined in both geographical and ethnic - cultural terms. With a population of 2.04 billion living in South Asia, it contains a quarter (25%) of the world's population. As commonly conceptualised, the modern states of South Asia include Bangladesh , Bhutan , India , the Maldives , Nepal , Pakistan , and Sri Lanka , with Afghanistan also often included, which may otherwise be classified as part of Central Asia . South Asia borders East Asia to

2200-495: Is dug, 6–9 metres (20–30 ft) wide, 2–2.5 metres (6 ft 7 in – 8 ft 2 in) deep, and 100–150 metres (330–490 ft) in circumference. A tall exhaust chimney is constructed in the centre. Half or more of the trench is filled with "green" (unfired) bricks which are stacked in an open lattice pattern to allow airflow. The lattice is capped with a roofing layer of finished brick. In operation, new green bricks, along with roofing bricks, are stacked at one end of

2310-451: Is manufactured differently for various purposes. Unfired bricks, also known as mudbrick , are made from a mixture of silt , clay , sand and other earth materials like gravel and stone, combined with tempers and binding agents such as chopped straw, grasses, tree bark , or dung. Since these bricks are made up of natural materials and only require heat from the Sun to bake, mudbricks have

2420-483: Is no clear boundary – geographical, geopolitical, socio-cultural, economical, or historical – between South Asia and other parts of Asia, especially Southeast Asia and West Asia. The common definition of South Asia is largely inherited from the administrative boundaries of the Indian Empire, with several exceptions. The current territories of Bangladesh , India , and Pakistan which were the core territories of

2530-814: Is surrounded by three water bodies – the Bay of Bengal , the Indian Ocean and the Arabian Sea  – and has acutely varied climate zones. The tip of the Indian Peninsula had the highest quality pearls. Most of this region is resting on the Indian Plate , the northerly portion of the Indo-Australian Plate , separated from the rest of the Eurasian Plate . The Indian Plate includes most of South Asia, forming

2640-544: The Brick Renaissance as the stylistic changes associated with the Italian Renaissance spread to northern Europe, leading to the adoption of Renaissance elements into brick building. Identifiable attributes included a low-pitched hipped or flat roof, symmetrical facade, round arch entrances and windows, columns and pilasters, and more. A clear distinction between the two styles only developed at

2750-737: The British Empire from 1857 to 1947 also form the core territories of South Asia. The mountain countries of Nepal and Bhutan , two independent countries that were not under the British Raj but were protectorates of the Empire, and the island countries of Sri Lanka and the Maldives are generally included. By various definitions based on substantially different reasons, the British Indian Ocean Territory and

2860-584: The Building Research Establishment in Watford , UK, the use of improved masonry for the construction of tall structures up to 18 storeys high was made viable. However, the use of brick has largely remained restricted to small to medium-sized buildings, as steel and concrete remain superior materials for high-rise construction. Four basic types of brick are un-fired, fired, chemically set bricks, and compressed earth blocks. Each type

2970-698: The Ganges and Indus river basins (where up to 60% of non-monsoon irrigation comes from the glaciers ) may be faced with severe water scarcity due to both climate and socioeconomic reasons. By 2030, major Indian cities such as Mumbai , Kolkata , Cuttack , and Kochi are expected to end up with much of their territory below the tide level. In Mumbai alone, failing to adapt to this would result in damages of US$ 112–162 billion by 2050, which would nearly triple by 2070. Sea level rise in Bangladesh will displace 0.9–2.1 million people by 2050 and may force

3080-634: The Himalayas and Kuen Lun mountain ranges and east of the Indus River and the Iranian Plateau , extending southward into the Indian Ocean between the Arabian Sea (to the southwest) and the Bay of Bengal (to the southeast). The climate of this vast region varies considerably from area to area from tropical monsoon in the south to temperate in the north. The variety is influenced by not only

3190-576: The Hindu Kush region of South Asia for several years and then later moved into the Indus valley region. Later, the Maurya Empire extended over much of South Asia in the 3rd century BCE. Buddhism spread beyond south Asia, through northwest into Central Asia. The Bamiyan Buddhas of Afghanistan and the edicts of Aśoka suggest that the Buddhist monks spread Buddhism (Dharma) in eastern provinces of

3300-777: The Indian subcontinent and is bounded by the Indian Ocean in the south, and the Himalayas , Karakoram , and Pamir Mountains in the north. Settled life emerged on the Indian subcontinent in the western margins of the Indus River Basin 9,000 years ago, evolving gradually into the Indus Valley Civilisation of the third millennium BCE. By 1200  BCE , an archaic form of Sanskrit , an Indo-European language , had diffused into India from

3410-597: The Kuru -Pañcāla union was the most influential. The first recorded state-level society in South Asia existed around 1000 BCE. In this period, states Samuel, emerged the Brahmana and Aranyaka layers of Vedic texts, which merged into the earliest Upanishads. These texts began to ask the meaning of a ritual, adding increasing levels of philosophical and metaphysical speculation, or "Hindu synthesis" . Increasing urbanisation of South Asia between 800 and 400 BCE, and possibly

3520-778: The Mature Harappan period, from 2600 to 1900 BCE. According to anthropologist Possehl , the Indus Valley civilisation provides a logical, if somewhat arbitrary, starting point for South Asian religions, but these links from the Indus religion to later-day South Asian traditions are subject to scholarly dispute. The Vedic period, named after the Vedic religion of the Indo-Aryans , lasted from c.  1900 to 500 BCE. The Indo-Aryans were Indo-European -speaking pastoralists who migrated into north-western India after

3630-592: The Partition of India into a Hindu-majority India and a Muslim-majority Pakistan, which resulted in significant displacement and violence and harder religious divides in the region. In 1947, the newly independent India and Pakistan had to decide how to deal with the hundreds of princely states that controlled much of the subcontinent, as well as what to do with the remaining European (non-British) colonies. A combination of referendums, military action, and negotiated accessions took place in rapid succession, leading to

3740-760: The Seleucid Empire , and possibly even farther into West Asia. The Theravada school spread south from India in the 3rd century BCE, to Sri Lanka, later to Southeast Asia. Buddhism, by the last centuries of the 1st millennium BCE, was prominent in the Himalayan region, Gandhara, Hindu Kush region, and Bactria. From about 500 BCE through about 300 CE, the Vedic-Brahmanic synthesis or "Hindu synthesis" continued. Classical Hindu and Sramanic (particularly Buddhist) ideas spread within South Asia, as well as outside South Asia. The Gupta Empire ruled over

3850-494: The Tibet Autonomous Region may be included as well. Myanmar (Burma), a former British colony and now largely considered a part of Southeast Asia, is also sometimes included. Afghanistan is also included by some sources. The South Asian Association for Regional Cooperation (SAARC), a contiguous block of countries, started in 1985 with seven countries – Bangladesh, Bhutan, India,

British, French, and Portuguese colonial interests struck treaties with these rulers and established their trading ports. In northwestern South Asia, a large region was consolidated into the Sikh Empire by Ranjit Singh . After the defeat of the Nawab of Bengal and Tipu Sultan and his French allies , British traders went on to dominate much of South Asia through divide-and-rule tactics by

4290-401: The 1940s, two rival camps had emerged among independence activists: those who favored a separate nation for Indian Muslims, and those who wanted a united India . As World War II raged, over 2 million Indians fought for Britain; by the end of the war, Britain was greatly weakened, and thus decided to grant independence to the vast majority of South Asians in 1947, though this coincided with

4400-536: The Arab general Muhammad bin Qasim conquered Sindh , and Multan in southern Punjab, in modern-day Pakistan. By 962 CE, 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

During the Early Middle Ages the use of bricks in construction became popular in Northern Europe , after being introduced there from Northwestern Italy. An independent style of brick architecture, known as brick Gothic (similar to Gothic architecture ) flourished in places that lacked indigenous sources of rocks. Examples of this architectural style can be found in modern-day Denmark, Germany, Poland, and Kaliningrad (former East Prussia ). This style evolved into

The Mughal Empire was marked by a period of artistic exchanges and a Central Asian and South Asian architecture synthesis, with remarkable buildings such as the Taj Mahal . However, this time also marked an extended period of religious persecution . Two of the religious leaders of Sikhism , Guru Arjan , and Guru Tegh Bahadur were arrested under orders of

5390-623: The Union. While meeting at the house, the delegates elected George W. Johnson to be the Confederate governor of Kentucky. From 1922 to 1942 the house was used as a funeral home , under the ownership of Wister C. Clark. His widow turned the ballroom into apartments in 1960, and the first floor was used as a law office by her son and his law partner.

5720-481: The area adjustment to Pakistan and western India records lower than 20%–30%. Climate of South Asia is largely characterised by monsoons. South Asia depends critically on monsoon rainfall. Two monsoon systems exist in the region: The warmest period of the year precedes the monsoon season (March to mid June). In the summer the low pressures are centered over the Indus-Gangetic Plain and high wind from

5830-785: The border of the regional structure, while the Pamir Mountains in Tajikistan are situated inside that border. The Indian subcontinent formerly formed part of the supercontinent Gondwana , before rifting away during the Cretaceous period and colliding with the Eurasian Plate about 50–55 million years ago and giving birth to the Himalayan range and the Tibetan plateau . It is the peninsular region south of

5940-405: The brick pile. Historically, a stack of unfired bricks covered for protection from the weather was called a "hack". Cooled finished bricks are removed from the other end for transport to their destinations. In the middle, the brick workers create a firing zone by dropping fuel (coal, wood, oil, debris, etc.) through access holes in the roof above the trench. The constant source of fuel maybe grown on

6050-465: The bricks are fired as they move slowly through the kiln on conveyors , rails, or kiln cars, which achieves a more consistent brick product. The bricks often have lime , ash, and organic matter added, which accelerates the burning process. The other major kiln type is the Bull's Trench Kiln (BTK), based on a design developed by British engineer W. Bull in the late 19th century. An oval or circular trench

6160-483: The broader Indo-Pacific . According to Saul Cohen, early colonial era strategists treated South Asia with East Asia, but in reality, the South Asia region excluding Afghanistan is a distinct geopolitical region separated from other nearby geostrategic realms, one that is geographically diverse. The region is home to a variety of geographical features, such as glaciers , rainforests , valleys , deserts , and grasslands that are typical of much larger continents. It

6270-444: The buildings more visible in the heavy fog and to help prevent traffic accidents. The transition from the traditional method of production known as hand-moulding to a mechanised form of mass-production slowly took place during the first half of the nineteenth century. The first brick-making machine was patented by Richard A. Ver Valen of Haverstraw, New York, in 1852. The Bradley & Craven Ltd 'Stiff-Plastic Brickmaking Machine'

6380-464: The chimney, where the rising gases create suction that pulls air through the system. The reuse of heated air yields savings in fuel cost. As with the rail process, the BTK process is continuous. A half-dozen labourers working around the clock can fire approximately 15,000–25,000 bricks a day. Unlike the rail process, in the BTK process the bricks do not move. Instead, the locations at which the bricks are loaded, fired, and unloaded gradually rotate through

6490-403: The collapse of the Indus Valley Civilization. Linguistic and archaeological data show a cultural change after 1500 BCE, with the linguistic and religious data showing links with Indo-European languages and religion. By about 1200 BCE, the Vedic culture and agrarian lifestyle were established in the northwest and northern Gangetic plain of South Asia. Rudimentary state-forms appeared, of which

6600-456: The colour of bricks to blend-in areas of brickwork with the surrounding masonry. An impervious and ornamental surface may be laid on brick either by salt glazing , in which salt is added during the burning process, or by the use of a slip , which is a glaze material into which the bricks are dipped. Subsequent reheating in the kiln fuses the slip into a glazed surface integral with the brick base. Chemically set bricks are not fired but may have

6710-513: The concerns of Pakistan and Bangladesh, particularly given the recurring conflicts between India and Pakistan, wherein the dominant placement of "India" as a prefix before the subcontinent might offend some political sentiments. However, in Pakistan, the term "South Asia" is considered too India-centric and was banned until 1989 after the death of Zia ul Haq . This region has also been labelled as "India" (in its classical and pre-modern sense) and " Greater India ". According to Robert M. Cutler –

6820-544: The construction materials for architectural wonders such as the Hanging Gardens of Babylon , where glazed fired bricks were put into practice. The earliest fired bricks appeared in Neolithic China around 4400 BC at Chengtoushan , a walled settlement of the Daxi culture . These bricks were made of red clay, fired on all sides to above 600 °C, and used as flooring for houses. By the Qujialing period (3300 BC), fired bricks were being used to pave roads and as building foundations at Chengtoushan. According to Lukas Nickel,

6930-431: The construction of canal , roads , and railways . Production of bricks increased massively with the onset of the Industrial Revolution and the rise in factory building in England. For reasons of speed and economy, bricks were increasingly preferred as building material to stone, even in areas where the stone was readily available. It was at this time in London that bright red brick was chosen for construction to make

7040-441: The construction of the tomb of China's first Emperor, Qin Shi Huangdi . The floors of the three pits of the terracotta army were paved with an estimated 230,000 bricks, with the majority measuring 28x14x7 cm, following a 4:2:1 ratio. The use of fired bricks in Chinese city walls first appeared in the Eastern Han dynasty (25 AD-220 AD). Up until the Middle Ages, buildings in Central Asia were typically built with unbaked bricks. It

7150-497: The country most likely to be the worst-affected. In the 2017 edition of Germanwatch 's Climate Risk Index , Bangladesh and Pakistan ranked sixth and seventh respectively as the countries most affected by climate change in the period from 1996 to 2015, while India ranked fourth among the list of countries most affected by climate change in 2015. Some research suggests that South Asia as a whole would lose 2% of its GDP to climate change by 2050, while these losses would approach 9% by

7260-518: The curing process accelerated by the application of heat and pressure in an autoclave. Calcium-silicate bricks are also called sandlime or flintlime bricks, depending on their ingredients. Rather than being made with clay they are made with lime binding the silicate material. The raw materials for calcium-silicate bricks include lime mixed in a proportion of about 1 to 10 with sand, quartz , crushed flint , or crushed siliceous rock together with mineral colourants . The materials are mixed and left until

7370-428: The early 16th century. The state religion of the sultanate was Islam. In South India , the Hindu Vijayanagara Empire came to power in 1336 and persisted until the middle of the 16th century. It was ultimately defeated and destroyed by an alliance of the Muslim Deccan sultanates at the Battle of Talikota . About 1526, the Punjab governor Dawlat Khan Lodī reached out to the Mughal Babur and invited him to attack

7480-574: The early 19th century. The region experienced significant de-industrialisation in its first few decades of British rule. Control over the subcontinent was then transferred to the British government after the Indian Rebellion of 1857 , with the British cracking down to some extent afterwards. An increase of famines and extreme poverty characterised the colonial period, though railways built with British technology eventually provided crucial famine relief by increasing food distribution throughout India. Millions of South Asians began to migrate throughout

7590-442: The end of the 19th century, the Hudson River region of New York State would become the world's largest brick manufacturing region, with 130 brickyards lining the shores of the Hudson River from Mechanicsville to Haverstraw and employing 8,000 people. At its peak, about 1 billion bricks were produced a year, with many being sent to New York City for use in its construction industry. The demand for high office building construction at

Ethnolinguistically , Northern South Asia is predominantly Indo-Aryan , along with Iranic populations in Afghanistan and Balochistan , and diverse linguistic communities near the Himalayas. Its borders have been heavily contested (primarily between India and its neighbours Pakistan and China , as well as separatist movements in Northeast India.) This tension in

7810-423: The first bricks with dimension 400x150x100 mm. Between 5000 and 4500 BC, Mesopotamia had discovered fired brick. The standard brick sizes in Mesopotamia followed a general rule: the width of the dried or burned brick would be twice its thickness, and its length would be double its width. The South Asian inhabitants of Mehrgarh also constructed air-dried mudbrick structures between 7000 and 3300 BC and later

7920-413: The future as the monsoon pattern intensifies. Across Asia as a whole, 100-year extremes in vapour transport (directly related to extreme precipitation) would become 2.6 times more frequent under 1.5 °C (2.7 °F) of global warming, yet 3.9 and 7.5 times more frequent under 2 °C (3.6 °F) and 3 °C (5.4 °F). In parts of South Asia, they could become up to 15 times more frequent. At

8030-454: The lime is completely hydrated; the mixture is then pressed into moulds and cured in an autoclave for three to fourteen hours to speed the chemical hardening. The finished bricks are very accurate and uniform, although the sharp arrises need careful handling to avoid damage to brick and bricklayer. The bricks can be made in a variety of colours; white, black, buff, and grey-blues are common, and pastel shades can be achieved. This type of brick

8140-409: The lowest-emission climate change scenarios . Under the high-emission scenario, 40 million people (nearly 2% of the South Asian population) may be driven to internal migration by 2050 due to climate change. India is estimated to have the world's highest social cost of carbon - meaning that it experiences the greatest impact from greenhouse gas emissions . Other estimates describe Bangladesh as

8250-480: The mesolithic sites as evidenced by the rock paintings of Bhimbetka rock shelters dating to a period of 30,000 BCE or older, as well as neolithic times. The Indus Valley civilisation , which spread and flourished in the northwestern part of South Asia from c.  3300 to 1300 BCE in present-day Pakistan , North India , and Afghanistan , was the first major civilisation in South Asia. A sophisticated and technologically advanced urban culture developed in

8360-401: The need for straw, which would prevent the likelihood of insects deteriorating the organic material of the bricks, subsequently weakening the structure. These ingredients are thoroughly mixed together by hand or by treading and are then left to ferment for about a day. The mix is then kneaded with water and molded into rectangular prisms of a desired size. Bricks are lined up and left to dry in

8470-506: The north, the Hindu Kush in the west, and the Arakanese in the east, and which extends southward into the Indian Ocean with the Arabian Sea to the southwest and the Bay of Bengal to the southeast. The terms " Indian subcontinent " and "South Asia" are sometimes used interchangeably. The Indian subcontinent is largely a geological term referring to the land mass that drifted northeastwards from ancient Gondwana , colliding with

8580-557: The north-Asian bitter cold winds, the temperatures are considerably moderate in the plains down below. For the most part, the climate of the region is called the monsoon climate, which keeps the region humid during summer and dry during winter, and favours the cultivation of jute , tea, rice, and various vegetables in this region. South Asia is largely divided into four broad climate zones: Maximum relative humidity of over 80% has been recorded in Khasi and Jaintia Hills and Sri Lanka, while

8690-480: The northeast, Central Asia to the northwest, West Asia to the west and Southeast Asia to the east. Apart from Southeast Asia, Maritime South Asia is the only subregion of Asia that lies partly within the Southern Hemisphere . The British Indian Ocean Territory and two out of 26 atolls of the Maldives in South Asia lie entirely within the Southern Hemisphere . Topographically, it is dominated by

8800-606: The northwest, with the Dravidian languages being supplanted in the northern and western regions. By 400  BCE , stratification and exclusion by caste had emerged within Hinduism , and Buddhism and Jainism had arisen, proclaiming social orders unlinked to heredity. In the early medieval era, Christianity , Islam , Judaism , and Zoroastrianism became established on South Asia's southern and western coasts. Muslim armies from Central Asia intermittently overran

8910-588: The northwestern and Indo-Gangetic Plain regions of South Asia. Several regions of South Asia were largely under Hindu kings such as those of the Vijayanagara Empire and the Kingdom of Mewar . Parts of modern Telangana and Andhra Pradesh were under local Muslim rulers, namely those of the Deccan sultanates. The Mughal Empire continued its wars of expansion after Babur's death. With the fall of

9020-480: The plains of northern India, eventually founding the Delhi Sultanate in the 13th century, and drawing the region into the cosmopolitan networks of medieval Islam . The Islamic Mughal Empire , in 1526, ushered in two centuries of relative peace, leaving a legacy of luminous architecture. Gradually expanding rule of the British East India Company followed, turning most of South Asia into

9130-552: The political integration of the vast majority of India and Pakistan within a few years. India and Pakistan clashed several times in the decades after Independence, with disputes over Kashmir playing a significant role. In 1971, the eastern half of Pakistan seceded with help from India and became the People's Republic of Bangladesh after the traumatic Bangladesh Liberation War . This, along with India and Pakistan gaining nuclear weapons soon afterwards, increased tensions between

9240-462: The region is defined. South Asia's northern, eastern, and western boundaries vary based on definitions used, while the Indian Ocean is the southern periphery. Most of this region rests on the Indian Plate and is isolated from the rest of Asia by mountain barriers. Much of the region consists of a peninsula in south-central Asia, rather resembling a diamond which is delineated by the Himalayas on

9350-667: The region, with persecution causing millions of Hindus and Christians to flee Pakistan and Bangladesh, and Hindu nationalism having grown in India with the election of the Bharatiya Janata Party in 2014. A recent phenomenon has been that of India and China fighting on their border , as well as vying for dominance of South Asia , with China partnering with Pakistan and using its superior economy to attract countries surrounding India, while America and other countries have strengthened ties with India to counter China in

9460-420: The relocation of up to one third of power plants by 2030. Food security will become more uneven, and some South Asian countries could experience significant social impacts from global food price volatility. Infectious diarrhoea mortality and dengue fever incidence is also likely to increase across South Asia. Parts of South Asia would also reach "critical health thresholds" for heat stress under all but

9570-476: The same time, up to two-thirds of glacier ice in the Hindu Kush region may melt by 2100 under high warming, and these glaciers feed the water basin of over 220 million people. As glacier meltwater flow diminishes after 2050, Hydropower generation would become less predictable and reliable, while agriculture would become more reliant on the intensified monsoon than ever before. Around 2050, people living in

9680-468: The spread of urban diseases, contributed to the rise of ascetic movements and of new ideas which challenged the orthodox Brahmanism . These ideas led to Sramana movements, of which Mahavira ( c.  549 –477 BCE), proponent of Jainism , and Buddha ( c.  563  – c.  483 ), founder of Buddhism , was the most prominent icons. The Greek army led by Alexander the Great stayed in

9790-468: The structure was built, there are no windows on the sides of the building. The property has seen various changes over the years. In 1890 the interior staircase was replaced. The original kitchen, servants' quarters, and white-column front porch are no longer present. A double-brick stairway takes the place of the porch. In 1964, additions were made for the continued use of the Clark family. The structure

9900-476: The sun for three days on both sides. After the six days, the bricks continue drying until required for use. Typically, longer drying times are preferred, but the average is eight to nine days spanning from initial stages to its application in structures. Unfired bricks could be made in the spring months and left to dry over the summer for use in the autumn. Mudbricks are commonly employed in arid environments to allow for adequate air drying. Fired bricks are baked in

10010-494: The sun) until they were strong enough for use. The oldest discovered bricks, originally made from shaped mud and dating before 7500 BC, were found at Tell Aswad , in the upper Tigris region and in southeast Anatolia close to Diyarbakir . Mudbrick construction was used at Çatalhöyük , from c. 7,400 BC. Mudbrick structures, dating to c. 7,200 BC have been located in Jericho , Jordan Valley. These structures were made up of

10120-437: The temperature inside the kiln stayed at a level that caused the clay to shimmer with the colour of molten gold or silver. He also had to know when to quench the kiln with water so as to produce the surface glaze. To anonymous labourers fell the less skilled stages of brick production: mixing clay and water, driving oxen over the mixture to trample it into a thick paste, scooping the paste into standardised wooden frames (to produce

10230-506: The term Indian subcontinent began in the British Empire, and has been a term particularly common in its successors. South Asia as the preferred term is particularly common when scholars or officials seek to differentiate this region from East Asia. According to historians Sugata Bose and Ayesha Jalal , the Indian subcontinent has come to be known as South Asia "in more recent and neutral parlance." This "neutral" notion refers to

10340-414: The term brick denotes a unit primarily composed of clay , but is now also used informally to denote units made of other materials or other chemically cured construction blocks. Bricks can be joined using mortar , adhesives or by interlocking. Bricks are usually produced at brickworks in numerous classes, types, materials, and sizes which vary with region, and are produced in bulk quantities. Block

10450-560: The third century BC, when baked bricks of regular shape began to be employed for vaulting underground tombs. Hollow brick tomb chambers rose in popularity as builders were forced to adapt due to a lack of readily available wood or stone. The oldest extant brick building above ground is possibly Songyue Pagoda , dated to 523 AD. By the end of the third century BC in China, both hollow and small bricks were available for use in building walls and ceilings. Fired bricks were first mass-produced during

10560-500: The transition to Baroque architecture . In Lübeck , for example, Brick Renaissance is clearly recognisable in buildings equipped with terracotta reliefs by the artist Statius von Düren, who was also active at Schwerin ( Schwerin Castle ) and Wismar (Fürstenhof). Long-distance bulk transport of bricks and other construction equipment remained prohibitively expensive until the development of modern transportation infrastructure, with

10670-518: 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, plundering and looting these kingdoms. The raids did not establish or extend permanent boundaries of their Islamic kingdoms. The Ghurid Sultan Mu'izz al-Din Muhammad began a systematic war of expansion into North India in 1173. He sought to carve out

10780-625: The trench. The colour of fired clay bricks is influenced by the chemical and mineral content of the raw materials, the firing temperature, and the atmosphere in the kiln. For example, pink bricks are the result of a high iron content, white or yellow bricks have a higher lime content. Most bricks burn to various red hues; as the temperature is increased the colour moves through dark red, purple, and then to brown or grey at around 1,300 °C (2,370 °F). The names of bricks may reflect their origin and colour, such as London stock brick and Cambridgeshire White. Brick tinting may be performed to change

10890-642: The turn of the 20th century led to a much greater use of cast and wrought iron , and later, steel and concrete . The use of brick for skyscraper construction severely limited the size of the building – the Monadnock Building , built in 1896 in Chicago, required exceptionally thick walls to maintain the structural integrity of its 17 storeys. Following pioneering work in the 1950s at the Swiss Federal Institute of Technology and

11000-594: The two countries. The Cold War decades also contributed to the divide , as Pakistan aligned with the West and India with the Soviet Union ; other factors include the time period after the 1962 Sino-Indian War , which saw India and China move apart while Pakistan and China built closer relations. Pakistan has been beset with terrorism , economic issues , and military dominance of its government since Independence, with none of its Prime Ministers having completed

11110-429: The use of ceramic pieces for protecting and decorating floors and walls dates back at various cultural sites to 3000-2000 BC and perhaps even before, but these elements should be rather qualified as tiles . For the longest time builders relied on wood, mud and rammed earth, while fired brick and mudbrick played no structural role in architecture. Proper brick construction, for erecting walls and vaults , finally emerges in

11220-534: The west, and in the north to northeastern Iran, northern Afghanistan, and southern Uzbekistan . Identification with a South Asian identity was found to be significantly low among respondents in an older two-year survey across Bangladesh, India, Nepal, Pakistan, and Sri Lanka. The history of core South Asia begins with evidence of human activity of Homo sapiens , as long as 75,000 years ago, or with earlier hominids including Homo erectus from about 500,000 years ago. The earliest prehistoric culture have roots in

11330-557: The world , impelled by the economic/ labour needs and opportunities presented by the British Empire. The introduction of Western political thought inspired a growing Indian intellectual movement, and so by the 20th century, British rule began to be challenged by the Indian National Congress , which sought full independence under the leadership of Mahatma Gandhi . Britain, under pressure from Indian freedom fighters, increasingly gave self-rule to British India. By

11440-412: The world. In 2022, South Asia had the world's largest populations of Hindus , Muslims , Sikhs , Jains, and Zoroastrians. South Asia alone accounts for 90.47% of Hindus, 95.5% of Sikhs, and 31% of Muslims worldwide, as well as 35 million Christians and 25 million Buddhists. The South Asian Association for Regional Cooperation (SAARC) is an economic cooperation organisation in the region which

11550-458: Was a uniformity to the brick sizes throughout the Indus Valley region, conforming to the 1:2:4, thickness, width, and length ratio. As the Indus civilization began its decline at the start of the second millennium BC, Harappans migrated east, spreading their knowledge of brickmaking technology. This led to the rise of cities like Pataliputra , Kausambi , and Ujjain , where there was an enormous demand for kiln-made bricks. By 604 BC, bricks were

11660-503: Was built in 1820 by William First, an immigrant from England believed to be a cabinetmaker. His surname was later altered to Forst. He built the home to show his expertise in millwork and mantels. In November 1861, the Confederate Sovereignty Committee met at the house. Its 116 delegates from 65 Kentucky counties voted to secede from the Union, although the state capital at Frankfort chose to stay in

11770-439: Was established in 1985 and includes all the nations comprising South Asia. The geographical extent is not clear cut as systemic and foreign policy orientations of its constituents are quite asymmetrical. Beyond the core territories of the Indian Empire (territories of the British Empire which were under the system of British Raj), there is a high degree of variation as to which other countries are included in South Asia. There

11880-750: Was hot, filthy work. Early civilisations around the Mediterranean , including the Ancient Greeks and Romans , adopted the use of fired bricks. By the early first century CE, standardised fired bricks were being heavily produced in Rome. The Roman legions operated mobile kilns , and built large brick structures throughout the Roman Empire , stamping the bricks with the seal of the legion. The Romans used brick for walls, arches, forts, aqueducts, etc. Notable mentions of Roman brick structures are

11990-517: Was only starting in the ninth century CE when buildings were entirely constructed using fired bricks. The carpenter's manual Yingzao Fashi , published in 1103 at the time of the Song dynasty described the brick making process and glazing techniques then in use. Using the 17th-century encyclopaedic text Tiangong Kaiwu , historian Timothy Brook outlined the brick production process of Ming dynasty China: ...the kilnmaster had to make sure that

12100-686: Was patented in 1853. Bradley & Craven went on to be a dominant manufacturer of brickmaking machinery. Henry Clayton, employed at the Atlas Works in Middlesex , England, in 1855, patented a brick-making machine that was capable of producing up to 25,000 bricks daily with minimal supervision. His mechanical apparatus soon achieved widespread attention after it was adopted for use by the South Eastern Railway Company for brick-making at their factory near Folkestone . At
