World Animal Day is celebrated annually on October 4th . Historically, this date commemorates the death of St. Francis, the founder of the monastic order of the same name and the patron saint of animals and the environment. The holiday is not officially recognized internationally, but is widely observed by animal rights organizations worldwide.
The tradition of celebrating an annual animal rights day can be traced back to Warsaw-born Heinrich Zimmermann, a German journalist, publisher, and animal rights activist. Heinrich published the magazine Mensch und Hund (Man and Dog), dedicated to pet care, where he actively promoted his ideas.
Heinrich and his associates organized the first World Animal Day on March 24, 1925. From the outset, the journalist had proposed October 4 as the date, but the only date available at the Berlin Sports Palace was in March. Such an impressive building was necessary, as 5,000 people attended the celebrations. It was only four years later that Zimmermann was able to hold the event in October. Initially, the holiday was celebrated in Germany, Austria, Switzerland, and Czechoslovakia, but the tireless efforts of activists led to its international recognition in 1931. Participants at a congress of animal rights activists in Florence unanimously supported this proposal. Sadly, with the rise of the Nazis to power, Zimmermann’s life was tragically cut short.
There are numerous days around the world, including international and officially recognized ones, dedicated to animal issues. The significance of October 4th is that World Animal Day doesn’t focus on any particular aspect or problem specific to a single species. It calls for a comprehensive approach: animal cruelty, the use of animals in agriculture, laboratory animals, rare and endangered species, and so on. The holiday addresses the root of the problem: animals are living and sentient beings, and they deserve to live a happy life.
The problem of human-animal relations has a history almost as long as that of humanity itself. While some religions considered all life on the planet equally valuable, others deified animals or, conversely, recognized humans’ right to own them. Medieval theologians already posed questions about whether animals have souls, and philosophers and thinkers of the modern era directly addressed questions of morality and ethics in relation to our smaller brothers and sisters.
A true revolution occurred in the 1970s, with the publication of Peter Singer’s Animal Liberation, a book often considered the bible of the animal rights movement. Singer draws direct parallels between animal exploitation and discrimination based on skin color, and rejects intelligence as the boundary between animals and humans, comparing chimpanzees to infants. The book sparked a great deal of interest and sparked a surge of scientific interest in the issue. More has been written about animal rights in the next 20 years than in the previous 2,000 years.
Of course, not all scientists agree, and even the very phrase “animal rights” is subject to criticism. There’s also disagreement among animal rights activists. While some call for radical veganism, others simply seek more humane treatment of animals. Ordinary pet owners are also interested in the issue, one way or another. They agree on one thing: no one, human or animal, should suffer excessively.
The first practical measures to protect animals were taken in Great Britain. Even before the 19th century, trials for cruelty to animals were known, but all ended in vain. The law considered animals to be property, and a fine could only be imposed if the defendant “caused injury” to the animal’s owner. It was only in 1821, through the efforts of Richard Martin, known as “Human Dick,” that a law on cruelty to animals was passed. Martin also prosecuted the world’s first person convicted of cruelty to animals—a dealer who had brutally beaten his donkey. Remarkably, the donkey itself testified as a “witness” during the trial; the jury was astonished by the animal’s condition and unanimously convicted.
The British founded the first animal welfare society, the Royal Society for the Prevention of Cruelty to Animals. Queen Victoria, an opponent of vivisection, personally granted the society this status. The society still exists today, and it has never ceased its activities. The British, known for their love of pets, did not forget them even during the world wars. During World War I, the society raised funds for veterinary medications for horses on the battlefield, and during World War II, volunteers rescued forgotten and lost animals from the rubble of London during the bombings. It is claimed that over 10,000 animals were saved. Even the Allied Lend-Lease convoys to the USSR carried horse care kits prepared by society members.
Similar societies have been and continue to be established around the world. Some focus on saving specific endangered species, others on caring for homeless animals, advocating for the prohibition of animal testing, and so on. In most cases, these are non-profit organizations that rely on donations. Such foundations and public associations often support individual volunteer projects, animal shelters, and other initiatives.
One such organization, the British Naturewatch Foundation, works closely with concerned citizens and the British police, helping to identify and investigate cases of animal cruelty. This organization is also noteworthy because they “introduced” World Animal Day online and created the holiday’s website.
The book “Animal Liberation”The foundation offers some suggestions on how to celebrate this day. Of course, the best option is to make a donation to local animal rights organizations, or, ideally, volunteer yourself. You can also simply post on social media, include the Day logo in your photo, or host a small vegetarian party. Book lovers can visit our library and read the book that has so captivated both scholars and ordinary people alike: Peter Singer’s “Animal Liberation.”
