A mother in Brazil faced intense backlash after posting a picture of her son in blackface and shackles as part of a slave costume.

Just before Halloween, Sabrina Flor posted the offensive image to her Instagram account. In the photo, her 9-year-old son was covered in brown body paint from head to toe, shackles, chains and whipping marks on his back.

Flor dressed her son in the costume for a party hosted by the child’s private school in the northeastern city of Natal, according to Daily Mail.

“When your child takes on the character! Let’s make this thing Brazilian,” Flor wrote in the caption, making light of the offensive costume.

Almost immediately after she posted the image, she was slammed in the comment section. She eventually apologized and said she isn’t a racist.

The apology, written in Portuguese, reads in English translation: “I just wanted to apologize for the fact! It has never been my intention to offend anyone, I am extremely sorry for everything that has happened,” a translation of the statement reads. I feel VERY wrong with the horrid curses and threats that they are sending me. Apologies to all, from the bottom of my heart! #Peace.”

For many, the mother’s decision to dress her son as a slave re-opened the deep wounds of South America’s dark history. During the 15^th century Trans-Atlantic Slave Trade, millions of Africans were kidnapped and transported to the country.

Brazil didn’t abolish slavery until 1888, making them the last country in the Western Hemisphere to do so.

Colegio CEI, where her son attends school, issued a statement condemning the costume and noted that it doesn’t condone any practices that promote slavery.

“Unfortunately, the choice of the costume for participation of Halloween, made by the student’s family, touched on a historical wound of our country,” the private school said.
