The 1969 Curaçao uprising (known as Trinta di Mei in Papiamento, the local language) was series of riots lasting from May 30 to June 1, 1969. They arose from a labor dispute on the Dutch-controlled Caribbean island nation of Curaçao. Riots destroyed a substantial portion of the island's main city and resulted in the resignation of the prime minister as well as a social prestige for the local language Papiamento.
