Roadways are the major means of transportation, while the city also has rail connectivity. The nearest airport is Tiruchirapalli International Airport, located away from the city. The nearest seaport is Karaikal, which is away from Thanjavur. The city first rose to prominence during the reign of the Cholas when it served as the capital of the empire. After the fall of the Cholas, the city was ruled by  various dynasties such as the Mutharaiyar dynasty, the Pandyas, the Vijayanagar Empire, the Madurai Nayaks, the Thanjavur Nayaks, the Thanjavur Marathas and the British Empire. It has been a part of independent India since 1947. Etymology. The city's name "Thanjavur" is believed to be derived from the name of a Mutharayar king, "Thananjay" or "Dhananjaya". Thananjaya (Dhananjaya) added to -Oor gives the name Thanjavur. The Kalamalla stone inscription (the first stone inscription) was made by the Renati Chola king, Erikal Muthuraju Dhanunjaya Varma of 575 CE. The city's name is also believed to be derived from the term  'thanjam puguntha oor' which means "the town for refugees", Thanjam puguntha oor-Thanjavur. The term also refers to the hospitality of the natives.However, according to a local legend, the word "Thanjavur" was derived from "Tanjan", who was a Demon who was killed on this very place and that asura asked to make a beautiful city there in Hindu mythology and later the asura(giant) was killed in what is now Thanjavur (formerly Tanjore) by the Hindu god Neelamegha Perumal, a form of Vishnu. History. This place was previously called Śiyāli. Indra once fled to this place in fear of the  asura called Śūrapadma and did tapas here. There are no references to Thanjavur in the Sangam period (third century BCE to fourth century CE) Tamil records, though some scholars believe that the city has existed since that time. Kovil Venni, situated to the east of the city, was the site of the Battle of Venni between the Chola king Karikala and a confederacy of the Cheras and the Pandyas. The Cholas seemed to have faced an invasion of the Kalabhras in the third century CE after which the kingdom faded into obscurity. The region around present day Thanjavur was conquered  by the Mutharayars during the sixth century, who ruled it up to 849. The Cholas came to prominence once more through the rise of the Medieval Chola monarch Vijayalaya (841–878) in about 850. Vijayalaya conquered Thanjavur from the Mutharayar king Elango Mutharayar and built a temple dedicated to the Hindu goddess Nisumbhasudani. His son Aditya I (871–901) consolidated their hold over the city. The Rashtrakuta king Krishna II (878–914), a contemporary of the Chola king Parantaka I (907–950), claims to have conquered Thanjavur, but there are no records to support the claim. Gradually, Thanjavur became the most important city in  the Chola Empire and remained its capital till the emergence of Gangaikonda Cholapuram in about 1025. During the first decade of the eleventh century, the Chola king Raja Raja Chola I (985–1014) constructed the Brihadeeswarar Temple at Thanjavur. The temple is considered to be one of the best specimens of Tamil architecture. When the Chola Empire began to decline in the 13th century, the Pandyas from the south invaded and captured Thanjavur twice, first between 1218–19 and again in 1230. During the second invasion, the Chola king Rajaraja III (1216–56) was exiled and he sought the help of the Hoysala  king Vira Narasimha II (1220–35) to regain Thanjavur. Thanjavur was eventually annexed along with the rest of the Chola kingdom by the Pandya king Maravarman Kulasekara Pandyan I (1268–1308) in 1279 and the Chola kings were forced to accept the suzerainty of the Pandyas. The Pandyas ruled Thanjavur from 1279 to 1311 when their kingdom was raided by the forces of Malik Kafur (1296–1306) and later annexed by the Delhi Sultanate. The Sultanate extended its authority directly over the conquered regions from 1311 to 1335 and then through the semi-independent Ma'bar Sultanate from 1335 to 1378. Starting from the  1350s, the Ma'bar Sultanate was steadily absorbed into the rising Vijayanagar Empire. Thanjavur is believed to have been conquered by Kampanna Udayar during his invasion of Srirangam between 1365 and 1371. Deva Raya's inscription dated 1443, Thirumala's inscription dated 1455 and Achuta Deva's land grants dated 1532 and 1539 attest Vijayanagar's dominance over Thanjavur. Sevappa Nayak (1532–80), the Vijayanagar viceroy of Arcot, established himself as an independent monarch in 1532 (1549, according to some sources) and founded the Thanjavur Nayak kingdom. Achuthappa Nayak (1560–1614), Raghunatha Nayak (1600–34) and Vijaya Raghava Nayak (1634–73) are some of the  important rulers of the Nayak dynasty who ruled Thanjavur. Thanjavur Nayaks were notable for their patronage of literature and arts. The rule of the dynasty came to an end when Thanjavur fell to the Madurai Nayak king Chokkanatha Nayak (1662–82) in 1673. Vijaya Raghunatha Nayak, the son of Chokkanatha, was killed in a battle and Chokkanatha's brother Alagiri Nayak (1673–75) was crowned as the ruler of the empire. Thanjavur was successfully conquered in 1674 by Ekoji I (1675–84), the Maratha feudatory of the sultan of Bijapur and half-brother of Shivaji (1627/30-80) of the Bhonsle dynasty. Ekoji founded  the Thanjavur Maratha kingdom which ruled Thanjavur till 1855. The Marathas exercised their sovereignty over Thanjavur throughout the last quarter of the 17th and the whole of the 18th century. The Maratha rulers patronized Carnatic music. In 1787, Amar Singh, the regent of Thanjavur, deposed the minor Raja, his nephew Serfoji II (1787–93) and captured the throne. Serfoji II was restored in 1799 with the assistance of the British, who induced him to relinquish the administration of the kingdom and left him in charge of Thanjavur fort and surrounding areas. The kingdom was eventually absorbed into British India in 1855  by the Doctrine of Lapse when Shivaji II (1832–55), the last Thanjavur Maratha ruler, died without a legitimate male heir. The British referred to the city as Tanjore in their records. Five years after its annexation, the British replaced Negapatam (modern-day Nagapattinam) with Thanjavur as the seat of the district administration. Under the British, Thanjavur emerged as an important regional centre. The 1871 India census recorded a population of 52,171, making Thanjavur the third largest city in the Madras Presidency. After India's independence, Thanjavur continued as the district headquarters. Geography and climate. Thanjavur is located at The tributaries  of river Cauvery, namely, the Grand Anaicut canal (Pudhaaru), Vadavaaru and Vennaaru rivers flow through the city. Thanjavur is situated in the Cauvery delta, at a distance of south-west of Chennai and east of Tiruchirappalli. While the plains immediately adjoining the Cauvery river have been under cultivation from time immemorial, most of Thanjavur city and the surrounding areas lie in the "New Delta" – a dry, barren upland tract which was brought under irrigation during the early 19th century. To the south of Thanjavur city, is the Vallam tableland, a small plateau interspersed at regular intervals by ridges of sandstone . The nearest seaport is Nagapattinam which is east of Thanjavur.
