On 14 December 1890, a document signed by Ruy Barbosa, then serving as Minister of Finance of the newly proclaimed First Brazilian Republic, ordered the burning of all records on the purchase and sale of slaves in Brazil, including registration books, customs duties and tax records. The document determined that the records be sent to Rio de Janeiro, then the country's capital, where they would be burned.[1][2][3] The burning of the records took place on 13 May 1891, the second anniversary of the abolition of slavery in the country.[1]
