Blue Party

The Blue Party (Spanish: Partido Azul), also nicknamed together The Tailless (Spanish: Los Bolos), was a historical Dominican political party from the late 19th century to the mid 20th century. Ulises Heureaux and Juan Isidro Jimenes Pereyra were the main leaders of this party, and were opposed to Los Coludos (Spanish for "The Long-tailed Ones") or Red Party, led by Horacio Vásquez

The name of the party came from the popularity of rooster fighting in the late 19th and early 20th century, and Bolos literally means Tailless. The Blue Party was banned in 1930 after Rafael Trujillo’s coup. It’s ideological heir is the Liberal Party of the Dominican Republic.
