Pandya Nadu in the context of "Three Crowned Kings"

The Pandya dynasty (Tamil: [paːɳɖijɐr]), also referred to as the Pandyas of Madurai, was an ancient Tamil dynasty of South India, and among the four great kingdoms of Tamilakam, the other three being the Pallavas, the Cholas and the Cheras. Existing since at least the 4th to 3rd centuries BCE, the dynasty passed through two periods of imperial dominance, the 6th to 10th centuries CE, and under the 'Later Pandyas' (13th to 14th centuries CE). In the second half of the 13th century under Jatavarman Sundara Pandyan I and Maravarman Kulasekara Pandyan I, the Pandyas ruled extensive territories including regions of present-day South India and northern Sri Lanka through vassal states subject to Madurai. The Pandya dynasty is the longest ruling dynasty in the world.

The rulers of the three Tamil dynasties were referred to as the "three crowned rulers (the mu-ventar) of the Tamil Region" in the southern part of India. The origin and the timeline of the Pandya dynasty are difficult to establish. The early Pandya chieftains ruled their country (Pandya Nadu) from the ancient period, which included the inland city of Madurai and the southern port of Korkai. The Pandyas are celebrated in the earliest available Tamil poetry (Sangam literature). Graeco-Roman accounts (as early as the 4th century BCE), the edicts of Maurya emperor Ashoka, coins with legends in Tamil-Brahmi script, and Tamil-Brahmi inscriptions suggest the continuity of the Pandya dynasty from the 3rd century BCE to the early centuries CE. The early historic Pandyas faded into obscurity upon the rise of the Kalabhra dynasty in south India.

The Vaigai is a river in the Tamil Nadu state of southern India; it passes through the towns of Theni, Madurai, Manamadurai, Paramakudi and Ramanathapuram. It originates in Varusanadu Hills, the Periyar Plateau of the Western Ghats range, and flows northeast through the Kambam Valley, which lies between the Palani Hills to the north and the Varushanad Hills to the south. The Vattaparai Falls are located on this river. As it rounds the eastern corner of the Varushanad Hills, the river turns southeast, running through the region of Pandya Nadu. Madurai, the largest city in the Pandya Nadu region and its ancient capital, lies on the Vaigai. The river empties into the Palk Bay near Alagankulam, close to Pamban Bridge in Ramanathapuram District.

The Vaigai is 258 kilometres (160 mi) long, with a drainage basin 7,031 square kilometres (2,715 sq mi) large. This river flows through 5 districts namely Theni, Dindigul, Madurai, Sivagangai and Ramanathapuram and serves as a lifeline for 6 districts namely Theni, Dindigul, Madurai, Sivagangai, Virudhunagar and Ramanathapuram as farmers of all these districts are greatly depends on this river water.

The Kingdom of Travancore (/ˈtrævəŋkɔːr/), also known as the Thiruvithamkoor Kingdom (Malayalam: [t̪iɾuʋid̪aːŋɡuːr]) and Travancore State, was a kingdom that lasted from c. 1729 until 1949. It was ruled by the Travancore royal family from Padmanabhapuram, and later Thiruvananthapuram. At its zenith, the kingdom covered most of the south of modern-day Kerala (Idukki, Kottayam, Alappuzha, Pathanamthitta, Kollam, and Thiruvananthapuram districts, major portions of Ernakulam district, Puthenchira village of Thrissur district) and the southernmost part of modern-day Tamil Nadu (Kanyakumari district and some parts of Tenkasi district) with the Thachudaya Kaimal's enclave of Irinjalakuda Koodalmanikyam temple in the neighbouring kingdom of Cochin. However Tangasseri area of Kollam city and Anchuthengu near Attingal in Thiruvananthapuram were parts of British India.

Malabar District of Madras Presidency was to the north, the Madurai and Tirunelveli districts of Pandya Nadu region in Madras Presidency to the east, the Indian Ocean to the south, and the Arabian Sea to the west.

The Kingdom of Polonnaruwa (Sinhala: පොළොන්නරුව රාජධානිය, romanized: Polonnaruwa Rājādhaniya) was the Sinhalese kingdom that expanded across the island of Sri Lanka from 1070 until 1232. The kingdom unified the island and started expanding its overseas influence during the reign of Parakramabahu the Great.

It had an influence in Pandya Nadu since its involvement in a civil war in the Pandya country. During this war, Pandya Nadu was seized as a country administered by the military of Polonnaruwa and Vira Pandyan of Pandya Dynasty. The tributaries of the Chola empire such as Tondi and Pasi came under its and Vira Pandya military rule. Rameshwaram was under Sinhalese and Vira Pandyan Alliance rule till 1182. Its currency Kahapana was struck in these places. During their influence on Pandya Nadu, construction work was undertaken. But Soon after their initial victory, Vira Pandyan army and Polonnaruwa army were defeated by Cholas and lost the control of Pandya Nadu, Tondi, pasi and Rameswaram. According to the Chola record at Tirukkollambudur of the fourth year of Kulottunga III (A.D. 1182) "the Singhalese soldiers had their noses cut off and rushed into the sea. Vira Pandya himself was compelled to retreat. The town of Madura was captured and made over to Vikrama Pandya." The war thus ended in favour of the Cholas, sometime in the 1170s.
