The Tamil people known as Tamilar, Tamilans or Tamils, are an ethnic group who speak the language Tamil as their mother tongue and trace their ancestry to Southern India and North-eastern Sri Lanka. Tamils, with a population of around 76 million and with a documented history stretching back over 2,000 years, are one of the largest and oldest extant ethnolinguistic groups in the modern world. Tamils constitute 5.9% of the population in India, 15.3% in Sri Lanka, 6% in Mauritius, 7% in Malaysia and 5% in Singapore. From the 14th century BCE onwards and mercantile activity along the western and eastern coasts of what is today Kerala and Tamil Nadu led to the development of four large Tamil political states, the Cheras, Cholas and Pallavas and a number of smaller states, all of whom were warring amongst themselves for dominance; the Jaffna Kingdom, inhabited by Sri Lankan Tamils, was once one of the strongest kingdoms of Sri Lanka, controlled much of the north of the island. Tamils were noted for their influence on regional trade throughout the Indian Ocean.
Artifacts marking the presence of Roman traders show direct trade was active between Rome and southern India, the Pandyas were recorded as having sent at least two embassies directly to Emperor Augustus in Rome. The Pandyas and Cholas were active in Sri Lanka; the Chola dynasty invaded several areas in Southeast Asia, including the powerful Srivijaya and the Malay city-state of Kedah. Medieval Tamil guilds and trading organizations like the Ayyavole and Manigramam played an important role in Southeast Asian trading networks. Pallava traders and religious leaders travelled to Southeast Asia and played an important role in the cultural Indianisation of the region. Scripts brought by Tamil traders to Southeast Asia, like the Grantha and Pallava scripts, induced the development of many Southeast Asian scripts such as Khmer, Javanese Kawi script and Thai; the Tamil language is one of the oldest extant written languages, with a history dating back to 300 BCE. Tamil literature is dominated by poetry Sangam literature, composed of poems composed between 300 BCE and 300 CE.
The most important Tamil author was the poet and philosopher Thiruvalluvar, who wrote the Tirukkuṛaḷ, a group of treatises on ethics, politics and morality considered the greatest work of Tamil literature. Tamil visual art is dominated by stylised Temple architecture in major centres and the productions of images of deities in stone and bronze. Chola bronzes the Nataraja sculptures of the Chola period, have become notable symbols of Hinduism. Tamil performing arts are divided into classical; the classical form of dance is Bharatanatyam, whereas the popular forms are known as Koothu and performed in village temples and on street corners. Tamil cinema, known as Kollywood, is an important part of the Indian cinema industry, it is the second largest film industry in India, next only to Bollywood. Music too is divided into many popular genres. Although most Tamils are Hindus, many those in the rural areas practice what is considered to be folk Hinduism, venerating a plethora of village deities. A sizeable number are Christians.
A small Jain community survives from the classical period as well. Tamil cuisine is informed by varied vegetarian and non-vegetarian items spiced with locally available spices; the music, the temple architecture and the stylised sculptures favoured by the Tamil people as in their ancient nation are still being learnt and practised. English historian and broadcaster Michael Wood called the Tamils the last surviving classical civilisation on Earth, because the Tamils have preserved substantial elements of their past regarding belief, culture and literature despite the influence of globalization, it is unknown as to whether the term Thamizhar and its equivalents in Prakrit such as Damela, Dameda and Damila was a self designation or a term denoted by outsiders. Epigraphic evidence of an ethnicity termed as such is found in ancient Sri Lanka where a number of inscriptions have come to light datable from the 6th to the 5th century BCE mentioning Damela or Dameda persons; the well-known Hathigumpha inscription of the Kalinga ruler Kharavela refers to a Tmira samghata dated to 150 BCE.
It mentions that the league of Tamil kingdoms had been in existence 113 years before then. In Amaravati in present-day Andhra Pradesh there is an inscription referring to a Dhamila-vaniya datable to the 3rd century CE. Another inscription of about the same time in Nagarjunakonda seems to refer to a Damila. A third inscription in Kanheri Caves refers to a Dhamila-gharini. In the Buddhist Jataka story known as Akiti Jataka there is a mention to Damila-rattha. There were trade relationship between the Roman Pandyan Empire; as recorded by Strabo, Emperor Augustus of Rome received at Antioch an ambassador from a king called Pandyan of Dramira. Hence, it is clear that by at least 300 B. C. the ethnic identity of Tamils was formed as a distinct group. Thamizhar is etymologically related to the language spoken by Tamil people. Southworth suggests that the name comes from tam-miz > tam-iz'self-speak', or'one's own speech'. Zvelebil suggests an etymology of tam-iz, with tam meaning "self" or "one's self", "-iz" having the connotation of "unfolding sound".
Alternatively, he suggests a derivation of tamiz < tam-iz < *tav-iz < *tak-iz, meaning in origin "the proper process". Possible evidence indicating the

The Vijayanagara Empire was based in the Deccan Plateau region in South India. It was established in 1336 by his brother Bukka Raya I of Sangama Dynasty; the empire rose to prominence as a culmination of attempts by the southern powers to ward off Islamic invasions by the end of the 13th century. It lasted until 1646, although its power declined after a major military defeat in the Battle of Talikota in 1565 by the combined armies of the Deccan sultanates; the empire is named after its capital city of Vijayanagara, whose ruins surround present day Hampi, now a World Heritage Site in Karnataka, India. The writings of medieval European travelers such as Domingo Paes, Fernão Nunes, Niccolò Da Conti, the literature in local languages provide crucial information about its history. Archaeological excavations at Vijayanagara have revealed the empire's wealth; the empire's legacy includes many monuments spread over South India, the best known of, the group at Hampi. Different temple building traditions in South and Central India came together in the Vijayanagara Architecture style.
This synthesis inspired architectural innovation in Hindu temples' construction. Efficient administration and vigorous overseas trade brought new technologies such as water management systems for irrigation; the empire's patronage enabled fine arts and literature to reach new heights in Kannada, Telugu and Sanskrit, while Carnatic music evolved into its current form. The Vijayanagara Empire created an epoch in South Indian history that transcended regionalism by promoting Hinduism as a unifying factor. Karnata Rajya was another name for the Vijayanagara Empire, used in some inscriptions and literary works of the Vijayanagara times including the Sanskrit work Jambavati Kalyanam by King Krishnadevaraya and Telugu work Vasu Charitamu. Differing theories have been proposed regarding the origins of the Vijayanagara empire. Many historians propose that Harihara I and Bukka I, the founders of the empire, were Kannadigas and commanders in the army of the Hoysala Empire stationed in the Tungabhadra region to ward off Muslim invasions from the Northern India.
Others claim that they were Telugu people, first associated with the Kakatiya Kingdom, who took control of the northern parts of the Hoysala Empire during its decline. Irrespective of their origin, historians agree the founders were supported and inspired by Vidyaranya, a saint at the Sringeri monastery to fight the Muslim invasion of South India. Writings by foreign travelers during the late medieval era combined with recent excavations in the Vijayanagara principality have uncovered much-needed information about the empire's history, scientific developments and architectural innovations. Before the early 14th-century rise of the Vijayanagara Empire, the Hindu states of the Deccan – the Yadava Empire of Devagiri, the Kakatiya dynasty of Warangal, the Pandyan Empire of Madurai had been raided and attacked by Muslims from the north, by 1336 these upper Deccan region had all been defeated by armies of Sultan Alauddin Khalji and Muhammad bin Tughluq of the Delhi Sultanate. Further south in the Deccan region, a Hoysala commander, Singeya Nayaka-III declared independence after the Muslim forces of the Delhi Sultanate defeated and captured the territories of the Seuna Yadavas of Devagiri in 1294 CE.
He created the Kampili kingdom. Kampili existed near Gulbarga and Tungabhadra river in northeastern parts of the present-day Karnataka state, it ended after a defeat by the armies of Delhi Sultanate. The triumphant army led by Malik Zada sent the news of its victory, over Kampili kingdom, to Muhammad bin Tughluq in Delhi by sending a straw-stuffed severed head of the dead Hindu king. Within Kampili, on the day of certain defeat, the populace committed a jauhar in 1327/28 CE. Eight years from the ruins of the Kampili kingdom emerged the Vijayanagara Kingdom in 1336 CE. In the first two decades after the founding of the empire, Harihara I gained control over most of the area south of the Tungabhadra river and earned the title of Purvapaschima Samudradhishavara. By 1374 Bukka Raya I, successor to Harihara I, had defeated the chiefdom of Arcot, the Reddys of Kondavidu, the Sultan of Madurai and had gained control over Goa in the west and the Tungabhadra-Krishna River doab in the north; the original capital was in the principality of Anegondi on the northern banks of the Tungabhadra River in today's Karnataka.
It was moved to nearby Vijayanagara on the river's southern banks during the reign of Bukka Raya I, because it was easier to defend against the Muslim armies persistently attacking it from the northern lands. With the Vijayanagara Kingdom now imperial in stature, Harihara II, the second son of Bukka Raya I, further consolidated the kingdom beyond the Krishna River and brought the whole of South India under the Vijayanagara umbrella; the next ruler, Deva Raya I, emerged successful against the Gajapatis of Odisha and undertook important works of fortification and irrigation. Italian traveler Niccolo de Conti wrote of him as the most powerful ruler of India. Deva Raya II succeeded to the throne in 1424 and was the most capable of the Sangama Dynasty rulers, he quelled rebelling feudal lords as well as the Zamorin of Quilon in the south. He became overlord of the kings of Burma at Pegu and Tanasserim. Firuz Bahmani of Bahmani Sultanate entered into a treaty with Deva Raya I of Vijayanagara in 1407 that required the latter to pay Bahmani an annual trib

International Standard Serial Number
An International Standard Serial Number is an eight-digit serial number used to uniquely identify a serial publication, such as a magazine. The ISSN is helpful in distinguishing between serials with the same title. ISSN are used in ordering, interlibrary loans, other practices in connection with serial literature; the ISSN system was first drafted as an International Organization for Standardization international standard in 1971 and published as ISO 3297 in 1975. ISO subcommittee TC 46/SC 9 is responsible for maintaining the standard; when a serial with the same content is published in more than one media type, a different ISSN is assigned to each media type. For example, many serials are published both in electronic media; the ISSN system refers to these types as electronic ISSN, respectively. Conversely, as defined in ISO 3297:2007, every serial in the ISSN system is assigned a linking ISSN the same as the ISSN assigned to the serial in its first published medium, which links together all ISSNs assigned to the serial in every medium.
The format of the ISSN is an eight digit code, divided by a hyphen into two four-digit numbers. As an integer number, it can be represented by the first seven digits; the last code digit, which may be 0-9 or an X, is a check digit. Formally, the general form of the ISSN code can be expressed as follows: NNNN-NNNC where N is in the set, a digit character, C is in; the ISSN of the journal Hearing Research, for example, is 0378-5955, where the final 5 is the check digit, C=5. To calculate the check digit, the following algorithm may be used: Calculate the sum of the first seven digits of the ISSN multiplied by its position in the number, counting from the right—that is, 8, 7, 6, 5, 4, 3, 2, respectively: 0 ⋅ 8 + 3 ⋅ 7 + 7 ⋅ 6 + 8 ⋅ 5 + 5 ⋅ 4 + 9 ⋅ 3 + 5 ⋅ 2 = 0 + 21 + 42 + 40 + 20 + 27 + 10 = 160 The modulus 11 of this sum is calculated. For calculations, an upper case X in the check digit position indicates a check digit of 10. To confirm the check digit, calculate the sum of all eight digits of the ISSN multiplied by its position in the number, counting from the right.
The modulus 11 of the sum must be 0. There is an online ISSN checker. ISSN codes are assigned by a network of ISSN National Centres located at national libraries and coordinated by the ISSN International Centre based in Paris; the International Centre is an intergovernmental organization created in 1974 through an agreement between UNESCO and the French government. The International Centre maintains a database of all ISSNs assigned worldwide, the ISDS Register otherwise known as the ISSN Register. At the end of 2016, the ISSN Register contained records for 1,943,572 items. ISSN and ISBN codes are similar in concept. An ISBN might be assigned for particular issues of a serial, in addition to the ISSN code for the serial as a whole. An ISSN, unlike the ISBN code, is an anonymous identifier associated with a serial title, containing no information as to the publisher or its location. For this reason a new ISSN is assigned to a serial each time it undergoes a major title change. Since the ISSN applies to an entire serial a new identifier, the Serial Item and Contribution Identifier, was built on top of it to allow references to specific volumes, articles, or other identifiable components.
Separate ISSNs are needed for serials in different media. Thus, the print and electronic media versions of a serial need separate ISSNs. A CD-ROM version and a web version of a serial require different ISSNs since two different media are involved. However, the same ISSN can be used for different file formats of the same online serial; this "media-oriented identification" of serials made sense in the 1970s. In the 1990s and onward, with personal computers, better screens, the Web, it makes sense to consider only content, independent of media; this "content-oriented identification" of serials was a repressed demand during a decade, but no ISSN update or initiative occurred. A natural extension for ISSN, the unique-identification of the articles in the serials, was the main demand application. An alternative serials' contents model arrived with the indecs Content Model and its application, the digital object identifier, as ISSN-independent initiative, consolidated in the 2000s. Only in 2007, ISSN-L was defined in the
Carnatic music, Karnāṭaka saṃgīta, or Karnāṭaka saṅgītam, is a system of music associated with southern India, including the modern Indian states of Andhra Pradesh, Karnataka and Tamil Nadu, as well as Sri Lanka. It is one of two main subgenres of Indian classical music that evolved from ancient Hindu traditions, the other subgenre being Hindustani music, which emerged as a distinct form because of Persian or Islamic influences from Northern India; the main emphasis in Carnatic music is on vocal music. Although there are stylistic differences, the basic elements of śruti, swara, rāga, tala form the foundation of improvisation and composition in both Carnatic and Hindustani music. Although improvisation plays an important role, Carnatic music is sung through compositions the kriti – a form developed between the 14th and 20th centuries by composers such as Purandara Dasa and the Trinity of Carnatic music. Carnatic music is usually taught and learned through compositions. Carnatic music is performed by a small ensemble of musicians, consisting of a principal performer, a melodic accompaniment, a rhythm accompaniment, a tambura, which acts as a drone throughout the performance.
Other typical instruments used in performances may include the ghatam, morsing, venu flute and chitraveena. The greatest concentration of Carnatic musicians is to be found in the city of Chennai. Various Carnatic music festivals are held throughout India and abroad, including the Madras Music Season, considered to be one of the world's largest cultural events. Like all art forms in Indian culture, Indian classical music is believed to be a divine art form which originated from the Devas and Devis, is venerated as symbolic of nāda brāhman. Ancient treatises describe the connection of the origin of the swaras, or notes, to the sounds of animals and birds and man's effort to simulate these sounds through a keen sense of observation and perception; the Sama Veda, believed to have laid the foundation for Indian classical music, consists of hymns from the Rigveda, set to musical tunes which would be sung using three to seven musical notes during Vedic yajnas. The Yajur-Veda, which consists of sacrificial formulae, mentions the veena as an accompaniment to vocal recitations.
References to Indian classical music are made in many ancient texts, including epics like the Ramayana and Mahabharata. The Yajnavalkya Smriti mentions वीणावादन तत्त्वज्ञः श्रुतीजातिविशारदः ताळज्ञश्चाप्रयासेन मोक्षमार्गं नियच्छति. Carnatic music is based as it is today on musical concepts that were described in detail in several ancient works the Bharata's Natya Shastra and Silappadhikaram by Ilango Adigal. Owing to Persian and Islamic influences in North India from the 12th century onwards, Indian classical music began to diverge into two distinct styles — Hindustani music and Carnatic music. Commentaries and other works, such as Sharngadeva's Sangita Ratnakara, further elaborated on the musical concepts found in Indian classical music. By the 16th and 17th centuries, there was a clear demarcation between Carnatic and Hindustani music, it was at this time that Carnatic music flourished in Vijayanagara, while the Vijayanagar Empire reached its greatest extent. Purandara Dasa, known as the “father of Carnatic music”, formulated the system, used for the teaching of Carnatic music.
Venkatamakhin invented and authored the formula for the melakarta system of raga classification in his Sanskrit work, the Chaturdandi Prakasika. Govindacharya is known for expanding the melakarta system into the sampoorna raga scheme – the system, in common use today. Carnatic music was patronized by the local kings of the Kingdom of Mysore, Kingdom of Travancore, the Maratha rulers of Tanjore in the 18th through 20th centuries; some of the royalty of the kingdoms of Mysore and Travancore were themselves noted composers and proficient in playing musical instruments, such as the veena, rudra veena, ghatam, mridangam and swarabhat. Some famous court-musicians proficient in music were Veene Sheshanna and Veene Subbanna, among others. With the dissolution of the erstwhile princely states and the Indian independence movement reaching its conclusion in 1947, Carnatic music went through a radical shift in patronage into an art of the masses with ticketed performances organized by private institutions called sabhās.
During the 19th century, the city of Chennai emerged as the locus for Carnatic music. The main emphasis in Carnatic music is on vocal music. Like Hindustani music, Carnatic music rests on two main elements: rāga, the modes or melodic formulæ, tāḷa, the rhythmic cycles. Today, Carnatic music is presented by musicians in concerts or recordings, either vocally or through instruments. Carnatic music itself developed around musical works or compositions of phenomenal com
Krishnadevaraya was an emperor of the Vijayanagara Empire who reigned from 1509–1529. He is the third ruler of the Tuluva Dynasty. Presiding over the empire at its zenith, he is regarded as an icon by many Indians. Krishna Deva Raya earned the titles Andhra Bhoja and Mooru Rayara Ganda, he became the dominant ruler of the peninsula of India by defeating the Sultans of Bijapur, the Bahmani Sultanate and the Gajapatis of Odisha, was one of the most powerful Hindu rulers in India. Indeed, when the Mughal Emperor Babur was taking stock of the potentates of north India, Krishnadevaraya was rated the most powerful and had the most extensive empire in the subcontinent. Portuguese travellers Domingo Paes and Fernao Nuniz visited the Vijayanagara Empire during his reign. Krishna Deva Raya benefited from the able prime minister Timmarusu, regarded by the emperor as a father figure and was responsible for his coronation. Krishna Deva Raya was the son of Tuluva Narasa Nayaka, an army commander under Saluva Narasimha Deva Raya, who took control of the empire to prevent its disintegration and became the founder of the Tuluva Dynasty, the third Hindu Dynasty to rule Vijayanagara.
The emperor's coronation took place on the birthday of Hindu God Krishna. He built; the king was of medium height, had a cheerful disposition, was reputed to be respectful to foreign visitors, ruthless in maintaining the law, prone to fits of anger. He maintained himself to a high level of physical fitness through daily exercises. Travelogues indicate that the king was not only an able the administrator but an excellent general, leading from the front in battle and attending to the wounded; the south Indian poet Muku Timmana praised him as the destroyer of the Turkics. The rule of the king Krishna Deva Raya marks a period of much military success in Vijayanagara history. On occasion, the king was known to change battle plans abruptly and turn a losing battle into victory; the first decade of his rule was one of the long sieges, bloody conquests, victories. His main enemies were the Bahamani Sultans, the Gajapatis of Odisha, involved in constant conflict since the rule of Saluva Narasimha Deva Raya and the Portuguese, a rising maritime power which controlled much of the sea trade.
The feudal chiefs of Ummattur and Kammas of Dharanikota who rebelled against Vijayanagar rule were conquered and subdued. The annual affair of the raid and plunder of Vijayanagar towns and villages by the Deccan sultans came to an end during the Raya's rule. In 1509 Krishnadevaraya's armies clashed with the Sultan of Bijapur at Diwani and the Sultan Mahmud was injured and defeated. Yusuf Adil Khan was killed and the Raichur Doab was annexed. Taking advantage of the victory and the disunity of the Bahamani Sultans, the Raya invaded Bidar and Bijapur and earned the title "establisher of the Yavana kingdom" when he released Sultan Mahmud and made him de facto ruler; the Sultan of Golconda Sultan Quli Qutb Shah was defeated by Timmarusu, the prime minister of Sri Krishnadevaraya. He defeated many local rulers like Dharanikota Kammas who were the feudatory of Gajapati kings of Odisha and seized lands up to the Krishna river. Ganga Raja, the Ummatur chief, was defeated; the chief drowned in the Kaveri in 1512.
The region was made a part of the Srirangapatna province. In 1516-1517, he pushed beyond the Godavari river; the Surya Vamsi Gajapatis of Odisha ruled a vast land comprising Odisha. Krishna Deva Raya's success at Ummatur provided the necessary impetus to carry his campaign into Coastal Andhra region, in control of Gajapati Prataparudra Deva; the Vijayanagar army laid siege to the Udayagiri fort in 1512. The campaign lasted for a year. Krishna Deva Raya offered prayers at Tirupati thereafter along with his wives Tirumala Devi and Chinnama Devi; the Gajapati army was met at Kondaviduraju where the armies of Vijayanagara, after establishing a siege for a few months and heavy with initial defeats began to retreat, until Timmarusu upon discovering a secret entrance to the unguarded eastern gate of the fort launched a night attack culminating with the capture of the fort and the imprisonment of the greatest swordsman of his time, Prince Virabhadra, the son of Gajapati Emperor of Kalinga-Utkal, Gajapati Prataprudra Deva.
Saluva Timmarasa took over as governor of Kondavidu thereafter. The Vijayanagar army accosted the Adapa Kamma dynasty army allies to Gajapatis at Kondapalli area and laid another siege. Krishnadevaraya planned for an invasion of mainland Kalinga-Utkal but the Gajapati Emperor, privy of this plan had built up a strategy to rout the Vijayanagara army and along with it its king, Krishnadevaraya; the confrontation was to happen at the fort of Kalinganagar. But the wily Timmarusu secured the information by bribing a Telugu deserter under the service of the mighty Prataprudra deva. Prataprudra was driven to Cuttack, the capital of the Gajapati empire and surrendered to Vijaynagar, giving his daughter Princess Annapurna Devi in marriage to Sri Krishna Deva Raya; as per treaty, the Krishna river became boundary of Odisha Kingdom. Krishna Deva Raya established friendly relations with the Portuguese, who set up the Portuguese Dominion of India in Goa in 1510; the Emperor obtained Arabian horses from the Portuguese merchants.
He utilized Portuguese expertise in
