Gadhimai festival

Gadhimai festival is a sacrificial ceremony held every five years in Nepal at the Gadhimai Temple of Bariyarpur, in Bara District, about south of the capital Kathmandu, and about east of the city of Kalaiya, near the Indo-Nepal border. It is primarily celebrated by Madhesi people. The event involves large-scale sacrificial slaughter of animals including water buffalo, pigs, goats, chickens, and pigeons, with the goal of pleasing Gadhimai, the goddess of power. People also offer coconuts, sweets, red-coloured clothes, etc. The festival has been described as the world's largest animal sacrifice event.
It is estimated that 250,000 animals were sacrificed during the Gadhimai festival of 2009. In 2015, it was erroneously reported that Nepal's temple trust planned to cancel all future animal sacrifices at the festival.
Description of 2009 event.
Millions of people attend the festival each year. Participants believe that animal sacrifice to the Hindu goddess Gadhimai can end evil and bring prosperity.
A month before the ritual in 2009, Madheshi politicians realized there would be a "severe shortage" of goats for the ritual sacrifice, as well as for the consumption of mutton during the festival. They began a radio campaign urging farmers to sell their animals.
The festival started in the first week of November 2009 and ended in the first week of December (up to makar sankranti). Sacrificial animals included white mice, pigeons, roosters, ducks, swine, and male water buffalo. More than 20,000 buffalo were sacrificed on the first day. It is estimated that 250,000 animals were sacrificed during the Gadhimai festival of 2009. The ritual killings were performed by more than two hundred men in a concrete slaughterhouse near the temple.
Criticism.
The festival has prompted numerous protests by animal rights activists and Nepalese Hindus from Hill region. In 2009, activists made several attempts to stop the ritual, including Brigitte Bardot and Maneka Gandhi, who wrote to the Nepalese government asking them to stop the killings. A government official commented that they would not "interfere in the centuries-old tradition of the Madheshi people."
Ram Bahadur Bomjon, claimed by some of his supporters to be the reincarnation of the Buddha, said that he would attempt to stop the sacrifice at the festival, preaching nonviolence and offering a blessing at the place. His promise prompted the government to send additional forces to prevent any incident.
After the festival, the meat, bones, and hides of the animals have been sold to companies in India and Nepal. 
In October 2014, Gauri Maulekhi (People for Animals Uttarakhand trustee and Humane Society International [HSI] consultant) filed a petition against the illegal transportation of animals from India to Nepal for slaughter. After this, the Supreme Court of India passed an interim order directing the Government of India to prevent animals from being illegally transported across the border for sacrifice at Gadhimai. The court also asked animal protection groups and others to devise an action plan to ensure the court order would be implemented.
NG Jayasimha, HSI India representative, visited Nepal to ensure the ban was being adhered to. In an interview with the "Times of India", he said, "I am very pleased that we were able to sit down with the Nepali politicians, to speak up for the hundreds of thousands of innocent animals who are condemned to an utterly unjustified beheading at Gadhimai. We also spoke directly to the Gadhimai temple and the local magistrate, so they can be in no doubt of the overwhelming call for compassion. We sincerely hope that they will act to stop this unnecessary bloodshed".
On 28 July 2015, the festival was "banned" by HSI India, though this ban has no legal force.
Reactions.
In 2014, the Indian Ministry of Home Affairs directed the states of Bihar and Uttar Pradesh to monitor and make sure no animals got to Nepal for the festival.
Talks of termination of the festival.
Nepal's temple trust announced the cancellation of all future animal sacrifices at the country's Gadhimai festival in July 2015.
In 2019, it was reported that the festival took place but this time the sacrifice involved goats, rats, chicken, pigs, and pigeons, and the number of animals sacrificed was lower than during earlier events.
