The Pankararus were hunted and persecuted since the times of the Brazilian Empire, considered extinct around the 1890s. However, they silently resisted for over a century, concealing their rituals and origins. "A Corrida do Imbu" (The Run of Imbu) is one of the two most sacred annual rituals of the Pankararu ethnicity, to which the Katökinn people belong, along with their relatives Koiupanká, Geripankó, and Kalankós.
After the military dictatorship, they regrouped and organized publicly. This people can now sing, pray in their sacred vests, transforming into the Praiás. They continue to fight for the rights of their people, recognition of their lands, and ethnicity in the Sertão of the states of Alagoas and Pernambuco. The documentation of the ritual was done at the invitation of the Katökinn leaders in the city of Pariconha, Alagoas - Brazil.
