In a town along Brazil’s Amazon River, a deep-rooted rivalry divides the community each year during the annual Festival of Parintins, a celebration honoring St. John the Baptist through elaborate performances centered on two competing folkloric figures: the red bull, Garantido, and the black bull, Caprichoso.

The rivalry traces its origins to distinct local traditions linked to gratitude and vows for prosperity. Residents describe how the festivities began with rhythmical drumming to thank St. John the Baptist for healing and protection, while a group of siblings introduced a dancing black bull during solstice harvest celebrations, a practice imported from Portuguese settlers. Over time, the bulls acquired their respective identities—Garantido with a red heart symbol and Caprichoso marked by a blue star—and evolved into the focal point of a festival that now draws thousands of spectators.

What started as modest homegrown events have expanded into grand public spectacles held in an open-air stadium, featuring three consecutive nights of competitive artistic performances. Each troupe showcases elaborate floats, costumes, and choreography designed to capture themes drawn from local folklore and Indigenous heritage. A panel of judges scores the presentations, ultimately declaring one bull as the winner, a title that fuels intense local pride and competition.

This cultural divide runs far beyond the festival grounds. Devotees often refuse to even acknowledge the rival bull’s name. Families are known to enforce strict allegiances, with some refusing entry to those wearing opposing colors or severing social ties over conflicting loyalties. For example, supporters of Caprichoso display blue stars and flags prominently in their neighborhoods, while Garantido partisans embrace red décor and emphasize their bull’s deep historical roots and association with the working class.

The rivalry has also affected interpersonal relationships. One couple recounted how their sons were caught between competing parental loyalties, ultimately illustrating the stronger pull of tradition when the younger son identified with the red bull despite his mother’s blue allegiances. The tensions contributed in part to the couple’s eventual divorce. Meanwhile, other couples admit the festival’s results can spark quarrels and temporary estrangement.

Despite its intensity, the rivalry is generally viewed by locals as a spirited, if competitive, expression of cultural identity. However, the festival has occasionally faced controversy, including allegations of bribery and bias in judging. Recently, a public dispute between two prominent festival musicians further underscored the passions that the event inspires.

As the festival continues to evolve, the red and blue bulls remain powerful symbols of community, history, and rivalry in this remote Amazon River town.
