Suscia (or Sussa, Suça, Súcia, Sussia) is a folk dance from the state of Tocantins in Brazil.
 It is most predominant in cities like Peixe, Natividade and Arrais.
 The exact name of the dance is unknown, as every community has a slight variation of the word.
 There is also controversy around when and where the dance originated from.
 Some locals say that the Suscia was created by African slaves brought to the area by gold miners.
 After the workday was over, the slave owners would allow their subjects to dance.
 Others believe that the dance originated in the Quilombo itself.
 Quilombos were small villages inhabited by escaped slaves, a symbol of slave rebellion.
 Whatever is the origin of this dance, it has deep African slave roots and it is part of Brazilian history.
