History & Origin Of Pongal Festival
The origin of Pongal can be traced back to Sangam Age, a period extending from 200 BC to 300 AD. The festival was celebrated as Thai Niradal. During the period, unmarried girls prayed for agricultural prosperity of the country and for the purpose, they observed penance during the Tamil month of Margazhi, corresponding (December-January). All through the month, they abstained themselves from the consumption of milk and milk products. They didn't oil their hair throughout the month. The use of harsh words was strictly refrained by them. Ceremonial bath in the early morning was part of the ritual of the penance.The unmarried women worshipped Goddess Katyayani, one of the nine forms of Ma Durga. They carved image of the deity out of sand. The women broke their fast on the first day of the month of Thai (January-February). It was believed that the fast would bring abundant wealth, prosperity and bountiful crop for the year ahead. Tamil literature has mentioned the celebration of the festival of Thai Niradal and the observance of the penance, known as Pavai Nonbu. Both the festival and the penance were vividly described in Andal's Tiruppavai and Manickavachakar's Tiruvembavai. Chola King Kiluttunga used to present lands to the Veeraraghava temple at Tiruvallur, especially for the celebration of Pongal.This festival is mainly celebrated by Dravida in South who are devotees of Vishnu.The story is as follows
Thiruppavai
Andal was a 10th century Tamil poet who is revered as a saint in the southern parts of India. Infact, she is considered as one of the twelve Alvars (saints) and the only woman Alvar (saint) of Vaishnavism (a cult devoted to Lord Vishnu). She is also believed to be an incarnation of Sri Bhumi Devi, the Divine Consort of Sriman Narayana (a manifestation of Lord Vishnu). Andal Thiruppavai, the compilation of devotional poems sung by her, is still recited by devotees during the month of Margazhi.(in tamil calendar).
Early Life
The life history of Andal tells us that a person named Vishnucitta found her, as a little baby girl, under a Tulsi plant in the temple garden of Srivilliputtur. He gave her the name of Goda, meaning 'the gift of Earth'. Vishnucitta brought her up in an atmosphere of love and devotion towards the Lord. The intensity of her love and dedication towards the Lord grew so much that she decide to marry Sri Ranganatha, a form of Lord Vishnu.
Unusual Offering
As per Andal biography, as she grew, her determination to marry Lord Ranganatha also increased. She also started making a unique offering to the Lord. She used to wear a flower garland first herself and then offer it to God. As an explanation, she said that first wanted to see whether the garland looked good or not by wearing it herself and looking in the mirror. Only after she was convinced that the garland looked nice, did she offer it to God.
One day, her father saw her doing this and admonished her from repeating this act. Goda made a new garland for the Lord. It is said that the same night, Vishnucitta received a vision from the Lord, who told him that He heartily accepted Goda's offerings. From that day onwards, Goda came to be known as "Andal", the girl who "ruled" over the Lord.
Marrying the Lord
As Andal reached the marriageable age of 15, her father asked her to get married. She replied that she would marry only Sri Ranganatha. It is believed that after this incident, Vishnucitta again received a divine vision, in which the Lord instructed him to send Andal to Sri Ranganatha Temple. At the same time, the priests at Sri Ranganatha Temple also received a vision where the Lord ordered them to prepare for the marriage. It is said that after reaching Sri Ranganatha Temple, Andal married the Lord.
Andal Thiruppavai and Nacciyar Tirumoli
Andal composed two poetic works in her lifetime, both in Tamil. Even though she compiled the poems in her teenage years, they display a high level of literary and religious maturity. Her first work is known as Andal Thiruppavai. It is compilation of thirty verses, in which she imagines herself to be a cowherd girl who longs to serve Lord Krishna. The second compilation is known as Nacciyar Tirumoli, consisting of 143 verses. Through this poem, she disclosed her passionate yearning for Lord Vishnu.
Bhogi is said to be liked most by Lord Vishnu Who married Godadevi on this day

Legends of Pongal
Legend of Mount GovardhanThe first legend is associated with the first day of the festival i.e. Bhogi Ponga. It is related to Lord Indra, the God of Clouds and Rains, and Lord Krishna. The honor given by people to Lord Indra made him proud and arrogant. He started considering himself as the most powerful of all beings. When Lord Krishna came to know about this, he thought of teaching Indra a lesson. He convinced his cowherd friends to worship Mt. Govardhan rather than Lord Indra. This angered Lord Indra and he sent the clouds to generate non-stop thunder, lightning, heavy rains and flood the land where Krishna lived.
Lord Krishna had other plans in mind and he lifted up the Govardhan Mountain on his little finger, to protect village people and their cattle. The rains continued for three days. At last, Indra realized his mistake and divine power of the young boy. He promised humility and begged Krishna's forgiveness. Since then, Krishna allowed Bhogi (first day of Pongal) celebrations in honor of Indra. Since then, the festival of Pongal came into being. In other words, this day gave the starting point to the Pongal celebration and the festival got another name of Indran, from this legendary story

Legend of Lord Shiva
Another legend is associated with Mattu Pongal (the third day of Pongal). It involves Lord Shiva and his mount, Nandi the bull. It is said that once Shiva ordered Nandi to go to the Earth and deliver his message to the people that they should take oil bath every day and eat food once a month. However, the dozing Nandi could not hear the message right and told the people to eat everyday and take oil bath once a month. Shiva was furious, as due to Nandi's mistake, there will be lack of grains on earth. Now, Nandi would have to remain on earth to help humans plough the fields. Since then, 'Mattu Pongal' came to be dedicated to cattle and other domestic animals.
