From mice to monkeys: the rise of animal despots
In the 1950s, ecologist Peter Crowcroft documented the authoritarian reign of a house mouse named Bill, whose aggressive dominance over peers at a British research facility mirrored human dictatorships. His observations revealed how despotism emerges in animal societies-and what it teaches us about our own.
The experiment that exposed Bill's tyranny
Crowcroft's study began at a repurposed World War II bomber training base in Suffolk, where the UK government sought to curb grain losses caused by mice. Tasked with analyzing rodent behavior, Crowcroft introduced two mice-Bill and Charlie-into the same enclosure. Within moments, Bill attacked Charlie, establishing dominance. Over time, Crowcroft recorded Bill's oppressive rule, noting how he monopolized food and space, behaviors eerily reminiscent of human autocrats like Stalin or Mao.
Published in 1966, Crowcroft's book Mice All Over became a foundational text for researchers, including Justin Varholick, a biomedical scientist at Kennesaw State University. Varholick later built on the work, studying how confined lab mice form hierarchical structures. His 2019 study found that mice's social ranks shifted based on group dynamics, with dominance tested through a "tube test"-where the mouse that retreated first acknowledged submission.
Despotism across the animal kingdom
Bill's rule wasn't an anomaly. Baboons, banded mongooses, and naked mole rats also exhibit rigid dominance hierarchies. Chacma baboons in southern Africa, for instance, are led by despotic males who control foraging routes and mating rights. Behavioral ecologist Élise Huchard, who studied these primates in Namibia, described how dominant males chase females into treetops to prevent rival matings-sometimes with fatal consequences. "We've seen pregnant females fall and miscarry after such chases," she said.
Naked mole rats take despotism further. Their underground colonies are ruled by a single breeding female-the queen-who enforces her authority through aggressive shoving and tail-tugging. Laura Betzig, an anthropologist, noted that subordinates tolerate abuse because leaving the colony risks starvation. "They stick around and endure awful despots," she said.
When animals reject tyranny
Not all animal societies succumb to despotism. Northern muriquis, a monkey species in Brazil's Atlantic Forest, live in remarkably egalitarian groups. Primatologist Karen Strier, who has studied them for decades, described their "hippie-like" lifestyle: sharing food, avoiding conflict, and even hugging more often than fighting. "Females mate with multiple males in quick succession," she said, "and patience defines their interactions."
A 2004 study on olive baboons revealed how despotism can collapse. After tuberculosis killed aggressive males in a troop, peaceful males took over, fostering a more relaxed hierarchy that persisted for generations. Such shifts suggest that environment and genetics shape whether a society tolerates-or resists-tyranny.
Lessons for human societies
Researchers draw parallels between animal and human despotism. Betzig found that historical human autocrats, like Roman emperors, amassed wealth and harems-a pattern echoed in baboon troops. Yet humans also exhibit cooperation, as seen in Woody Guthrie's folk song celebrating collective achievements like defeating Hitler.
Marcy Ekanayake-Weber, a biological anthropologist, argued that human agriculture may have fueled patriarchal hierarchies, diverging from our egalitarian hunter-gatherer roots. Still, she emphasized the benefits of cooperation: "When we lean into egalitarianism, we become a superorganism-like ants moving objects no single ant could."
"Watching another primate that has such peaceful coexistence is an inspiration. It's a glimpse into another way of life we could aspire to."

The cost of oppression-and the power of escape
Despotism often thrives where escape is impossible. Betzig's research on historical human societies showed that autocrats flourished in geographically isolated regions. She warned against barriers to mobility: "Don't stop moving, don't put up walls."
Even ants illustrate this dynamic. A 2022 study found that one species prioritized group cohesion over ideal nest sites, choosing unity over division. For humans, Ekanayake-Weber suggested, the lesson is clear: "It behoves us to lean into cooperation."
