The battle takes place between a group of married men called Els Enfarinats that takes control of the village for one day, pronouncing a whole host of ridiculous laws and fining the citizens that infringe them, and another group called La Oposicio, which tries to restore order. Money collected from the fines is then donated to charitable causes in the village.
The fight, where 'soldiers' also spray fire extinguishers, is accompanied by a day of celebrations including fireworks and a mock election.
At 8am, the Els Enfarinats take the city under the slogan 'New Justice', and an hour later the 'Race for Mayor' takes place in which they decide who will be the 'leader; of the Els Enfarinats.
Then, the act of L'Aixavegó is carried out in the Plaça de l'Església (Church Square), where the Els Enfarinats reside.
Here, it is decided that those who do not pay the fine will go to jail. At midday, a collection called the Arreplegada dels Enfarinats takes place through the streets of the old quarter and of the city centre of Ibi, terminating in the Sant Joaquim Sanctuary.
They exercise their authority under a blaze of fireworks, flour bombs and eggs. At 5pm the authority of Els Enfarinats comes to an end giving way to the celebration of the traditional Dansà.
The Spanish are known for their bizarre food-throwing traditions. Every year they launch tomatoes at each other during the Tomatina Festival which takes place in the town of Bunol in August every year.
