The First Sangam () is also known as the First Academy, and as the Head Sangam (). The first Sangam (
mutaṟcaṅkam) is described as having been held at "the Madurai which was submerged by the sea", or known among historians as Kapatapuram, lasted a total of 4,400 years, and had 549 members, which supposedly included some gods of the
Hindu pantheon such as
Siva,
Kubera,
Murugan and
Agastya. A city was found submerged in Pondicherry and according to the location, has been popularly credited as being the site for the first Sangam, Kapatapuram. A total of 4,449 poets are described as having composed songs for this Sangam. There were 89 Pandiya kings starting from Kaysina valudi to Kadungon were decedents and rulers of that period. It was said to be located in
Then Madurai under the patronage of 89
Pandya kings. It is said to have lasted for 4,440 years, and this would put the First Sangam between 9600 BCE to 5200 BCE. Some are of the opinion that
Agathiyar was the head of the Head Sangam. However, this is unlikely as the first mention of him is from
Ptolemy and no
Sangam work refers to him. A more likely proposition is
Lord Muruga (Kartikeya) being the head of the First Sangam as believed by others. Its function was to judge literary works and credit their worth. Later literary works like
Iraiyanar Akaporul mention that 549 poets were members of it including
Shiva,
Murugan,
Kuperan and seven
Pandya kings. And 16,149 authors attended the convocation. Its chief works were Perumparipadal, Mudukuruku, Mudunarai and Kalariyavirai. It used
Agattiyam as its grammar. There are no surviving works from this period. Muranjiyur Mudinagar, a member of the first Tamil Sangam, is believed to have been a king of the Nagas in Jaffna.
Siddha medicine is said to have been practiced during the First Sangam, and people "enjoyed mental and bodily health, respecting nature and living hygienically." Iraiyanar Kalaviyal mentions that a King Kadungon was the last ruler during the Talaiccankam. He is not to be confused with
Kadungon who defeated the
Kalabhras. It was washed away in a sea-deluge. This led to the
Middle Sangam. ==Second legendary sangam==
