The Coalition Power Triangle
Three-player alliances where the kingmaker holds real power
In the Arnhem chimpanzee colony, de Waal observed that power was never held by a single individual acting alone. Instead, dominance emerged from triangular coalitions where three key players constantly shifted alliances. The alpha male required a coalition partner to maintain his position, but the coalition partner -- often an older, post-prime individual -- held disproportionate influence because he could switch sides at will.
The framework reveals that formal rank and actual influence are two distinct layers of social organization. The individual who appears to be in charge (the alpha) may be deeply dependent on a behind-the-scenes power broker. Yeroen, the oldest male, exemplified this by supporting Nikkie as alpha while extracting mating privileges as payment -- effectively controlling the sexual economy despite being formally subordinate.
This pattern repeated across multiple leadership transitions: whoever controlled the swing vote in the triangle held the real strategic advantage. The lesson is that in any three-player power system, the most powerful position is often not the top seat but the pivotal middle position that both other players need.
- Formal rank and real influence are separate dimensions of power -- the person at the top is not always the most powerful
- In a three-player system, the swing player who can credibly switch sides holds disproportionate leverage
- Coalitions require ongoing maintenance through reciprocal exchanges -- support is never free
- An alpha who becomes too greedy with privileges risks losing the coalition partner who sustains his position
- Post-prime players can remain highly influential by positioning themselves as indispensable kingmakers
- Map the TriangleIdentify the three key players in your power environment: the current leader, the strongest challenger, and the potential swing player. Assess each player's formal authority versus their actual influence on outcomes.Pro tipThe swing player is often someone who appears to have lost relevance -- an elder statesman, a former leader, or someone with deep institutional knowledge and relationships.WarningDo not assume the person with the highest title holds the most power. Look at who actually controls information flow, resource allocation, and whose support others actively court.
- Assess Coalition DependenciesDetermine which alliances currently exist and what each party gains from them. Map the reciprocal exchanges: What is the alpha giving the coalition partner in return for support? What would the challenger offer to lure the swing player away?Pro tipYeroen extracted mating privileges from Nikkie in exchange for coalition support. In human terms, look for the currencies being traded: access, credit, resources, protection, or information.WarningCoalitions are inherently unstable. The moment one partner feels shortchanged, the entire arrangement can collapse overnight.
- Position Yourself StrategicallyIf you are the swing player, maintain credible relationships with both other parties so that your support remains valuable. If you are the alpha, ensure your coalition partner receives adequate returns. If you are the challenger, identify what the swing player wants that the current alpha is failing to provide.Pro tipYeroen's genius was maintaining just enough tension between Nikkie and Luit that both needed him. He never fully committed to either side, preserving his optionality.WarningBeing too obviously opportunistic can cause both other players to unite against you. Luit was killed precisely because both Yeroen and Nikkie perceived him as the greater threat.
- Monitor the Exchange BalanceContinuously track whether the reciprocal exchanges within your coalition remain fair. When one party starts taking more than they give, the partnership becomes fragile. Watch for signs of growing resentment or secret negotiations between your partner and your rival.Pro tipDe Waal observed that when Nikkie stopped letting Yeroen mate with estrus females, Yeroen immediately withdrew support and Luit reclaimed the alpha position within days.WarningThe collapse of a coalition can be catastrophically sudden. What looks stable for months can disintegrate in a single day if the exchange balance tips too far.
- Manage Transitions CarefullyWhen power shifts are inevitable, manage them to preserve relationships you may need later. Today's rival may be tomorrow's essential ally. Never burn bridges so thoroughly that reconciliation becomes impossible.Pro tipChimpanzees never retired to their sleeping quarters unreconciled. Even fierce rivals held 'evening truces' -- lengthy grooming sessions before separation. Build in reconciliation rituals after conflicts.WarningFailed transitions can turn lethal. Luit's death after Yeroen and Nikkie's coordinated attack shows that power struggles pushed too far can destroy all parties involved.
After being dethroned by Luit, Yeroen could have faded into irrelevance. Instead, he allied with the young Nikkie, helping him overthrow Luit. As the indispensable coalition partner, Yeroen extracted mating privileges that exceeded even the alpha's share. He played Nikkie and Luit against each other, screaming for help from whichever rival was absent when the other approached an attractive female.
Nikkie and Luit were each being manipulated by Yeroen, who would appeal to whichever male was not currently approaching a female. On September 5, something suddenly changed: both Nikkie and Luit began mating openly while Yeroen lay at a distance without interfering. De Waal concluded they had reached a wordless 'treaty' of mutual non-intervention.
In 1980, Nikkie became increasingly intolerant and refused to let Yeroen copulate with females. Yeroen withdrew his support overnight, and Luit instantly reclaimed the alpha position. Ten weeks later, Yeroen and Nikkie coordinated a nighttime attack on Luit that proved fatal.
De Waal documented two complete power takeovers at Arnhem Zoo between 1975 and 1980. In the first, Luit challenged and overthrew the aging alpha Yeroen through a combination of intimidation displays and systematic isolation tactics. In the second, the young Nikkie dethroned Luit by forming a coalition with the deposed Yeroen. What struck de Waal was that Yeroen -- the oldest and weakest of the three -- consistently extracted the most mating privileges by playing the two stronger males against each other, switching his support strategically.
This led de Waal to distinguish between formal dominance (who receives submissive greetings) and actual power (who influences group processes). The discovery mapped perfectly onto human political systems where behind-the-scenes operators often wield more influence than the official leader.
