Thrissur Pooram (Malayalam: തൃശ്ശൂര് പൂരം) is one of the most popular temple festivals of the South Indian state Kerala. It is held at Vadakkunnathan Temple every year on 'Pooram' (Malayalam: പൂരം, pronounced [puːɾam]) day of the Malayalam Calendar month of 'Medam'. 'Pooram' day is the day when the moon rises with the Pooram star.
Thrissur Pooram was the brain child of Raja Rama Varma or famously known as Sakthan Thampuran, the Maharaja of Cochin (1790–1805). Before the start of Thrissur Pooram, the largest temple festival in Kerala was the one-day festival held at Aarattupuzha knows as Arattupuzha Pooram. Temples in and around City of Thrissur were regular participants. One day because of incessant rains they were late for the Arattupuzha Pooram and were denied access to the Pooram procession. Felt embarrassed by the denial, the temples went to the Sakthan Thampuran and told their story.
So in 1798, he unified the 10 temples situated around Vadakkunnathan Temple and organised the celebration of Thrissur Pooram as a mass festival. He invited temples with their deities to City of Thrissur to pay obeisance to Lord Vakunnathan, the presiding deity of the Vadakkunnathan Temple. Sakthan Thampuran ordained these temples into two groups, Western group and Eastern group. The Western group as Thiruvambadi Sri Krishna Temple consisting of Kanimangalam, Laloor, Ayyanthole and Nethilakkavu as the main one.
The Eastern group called as Paramekkavu Bagavathi Temple, consisting in addition to Paramekkavu temple, Karamukku, Chembukavu, Choorakottukavu and Panamukkamppilly. The Pooram was to be centered around the Vadakkunnathan Temple, with all these temples sending their Poorams (the whole procession), to pay obeisance to the Shiva, the presiding deity. The Thampuran is believed to have chalked out the program and the main events of the Thrissur Pooram festival.

It is a one hour show by presented by Thiruvambady and Paramekkavu Devawsoms. Swaraj Round is venue for this fireworks and starts at 7:15 PM in the evening.

Farewell Ceremony 
The seventh day of Pooram is the last day of Pooram. Upacharam Cholli Piriyal (Farewell Ceremony) is last event held at Swaraj Round. Thiruvambadi Sri Krishna Temple and Paramekkavu Bagavathi Temple idols were taken from the Swaraj Round to their respective temples mark the end of the Pooram celebrations. The festival will end with display of fireworks know as Pakal Vedikkettu.
Cultural Influences 
Despite being a Hindu festival, the Thrissur pooram is attended by different sections of the Kerala society. Several replicas of the festival are held in places within Kerala  as well as outside the state.
For the fireworks ceremony, which is held as two parts - a sample one (called Sample Vedikkettu, held one day before the pooram) and the final one, chemicals are used extensively. This has caused several allegations against the organizers for violating the regulations regarding sound pollution. In the past, there were several accidents during the event as well during the manufacture of fireworks chemicals, which has caused in the deaths of several people.
Another topic of concern is the use of elephants. Due to the competitive nature of the festival between Paramekkavu and Thiruvambadi temples, as well as the presence of cheru poorams elephants are used continuously as well as in large numbers. This has caused elephants to collapse  as well as to run amok. This has caused concern among the animal activists as well as the common people. Though the government has issued several guidelines regarding the parading of elephants in the festivals, there are several allegations of them being not observed strictly.
