African slaves were excluded from participating in the celebrations and extravagant masquerade balls. However, with slavery ending in 1834 freed African slaves transformed the pre-Lenten European celebration into a celebration of the end of slavery that allowed them to celebrate their African heritage and culture and freedom through costumes, song, music, and dance. African dance and music traditions remodeled previous forms of carnival celebrations in the Americas, as African drum rhythms, stick fighters, enormous puppets, and stilt dancers started making their appearances in the carnival celebrations. Many of these components, dressing in masquerade, music, and dancing, continue to remain paramount to Carnival.
