Popobawa

Also known as Popo Bawa, Bat-wing

A shape-shifting night spirit of Zanzibar whose “bat-wing” shadow has sparked waves of panic since the 1960s, most famously in 1995.

The Popobawa is a shetani – a malevolent spirit – of the Zanzibar archipelago off the coast of Tanzania. Its Swahili name joins popo (bat) and bawa (wing), describing the dark, wing-like shadow it is said to cast as it arrives at night rather than its true shape, which shifts between a man, an animal and something invisible. It is best known not for sightings but for attacks: people describe being pinned in bed, beaten, and – most feared of all – sexually assaulted, and some say the spirit insists its victims tell others or it will return.

Most accounts trace it to Pemba Island in the mid-1960s, in the unsettled years after the 1964 Zanzibar Revolution. A popular origin story holds that a sheikh summoned a djinn to punish his neighbours and then lost control of it. Waves of reports followed in the 1970s and 1980s, and the spirit became woven into everyday talk on the islands.

The great scare came in 1995. Through the spring, rumours of nightly attacks swept Zanzibar Town and the countryside; families abandoned their beds to sit outside in groups around fires, and in April a mob killed a man they accused of being the Popobawa, who turned out to be a mentally ill visitor from the mainland. Many observers linked the timing to the tension before Zanzibar’s first multi-party elections that October – a pattern noted again in later flare-ups, and one reason locals sometimes call it an election-season spirit.

The Popobawa resurfaced briefly in 2000 and in 2007, when the BBC reported men in parts of Dar es Salaam sleeping in groups outdoors and smearing themselves with oil to ward it off. Scholars such as anthropologist Martin Walsh and linguist Katrina Daly Thompson have since treated it as a rich, many-layered piece of Swahili culture – a way of talking about politics, sexuality, power and memory – rather than simply a monster story.

What witnesses describe

Usually unseen. Victims describe a heavy, crushing presence, a foul smell, and sometimes a short, dark figure, a one-eyed dwarf or a large bat-like shape. It can reportedly take the form of a person, including someone the victim knows.

Where and when it’s seen

Homes at night on Pemba and Unguja, spreading in some years to Dar es Salaam and other towns on the Tanzanian coast. Waves of reports tend to cluster around times of social and political tension.

Notable sightings

1. c. 1965First reports on Pemba Pemba Island, Zanzibar

   Accounts collected by anthropologists place the spirit’s first appearance on Pemba in the mid-1960s, shortly after the Zanzibar Revolution. Local tradition holds that an early outbreak ended only when President Abeid Karume publicly challenged the spirit to appear.

2. Night of April 3, 1995The 1995 panic turns deadly Zanzibar Town, Unguja

   At the height of a months-long scare, a crowd killed a man it believed was the Popobawa; he was later identified as a psychiatric patient from the mainland. Residents across the islands were sleeping outdoors in groups, and the panic later spread to rural areas before fading.

3. February 2007Fear reaches Dar es Salaam Dar es Salaam, Tanzania

   The BBC reported men in parts of Tanzania’s largest city staying awake or sleeping outside in groups, some smearing themselves with pig’s oil as protection. Its correspondent noted that there were no actual sightings and that few people admitted to believing in the demon.

What could explain it?

• Sleep paralysis: investigator Joe Nickell noted that the classic attack – waking unable to move, a weight on the chest, a sense of an intruder – matches this common sleep phenomenon, which has produced “night hag” traditions worldwide.
• Mass hysteria and social contagion: reports spread by rumour, surge in waves and fade quickly, and researcher Benjamin Radford found that doctors at Zanzibar’s main hospital had not treated any physical victims.
• Political anxiety: outbreaks have repeatedly coincided with election periods, leading scholars to read the spirit as a way of voicing fear and resentment that could not be expressed openly.
• Cultural memory: anthropologists have suggested the stories also carry older memories of slavery, violence and power on the Swahili coast.

Legend, culture and tourism

The Popobawa is a living part of Swahili spirit belief alongside other mashetani and djinn, and is discussed in a matter-of-fact way on the islands. It has inspired Swahili-language films, academic books such as Katrina Daly Thompson’s Popobawa: Tanzanian Talk, Global Misreadings (2017), and countless retellings online. Visitors to Zanzibar’s Stone Town may hear it mentioned by guides, but it is not a tourist mascot – many people take it seriously.
