He became more aware of how the caste system, which separated the black masses from the other tribes, denied the marginalized communities access to education and employment, and further impeded their ability to ever gain independence.

[13] It was in the year 2007 that Zeine Ould Zeidane, former presidential candidate, offered Abeid work on his political program, advocating for the abolition of slavery and against discrimination.

Abeid accepted the offer and in the same year, following a hunger strike held together with three other activists, Mauritanian government officials arrested three women accused of holding children in slavery in the capital, Nouakchott.

[15] Later in 2008, Abeid founded the Initiative for the Resurgence of the Abolitionist Movement (IRA-Mauritania), which he defines as "an organization of popular struggle", and where he serves as president.

He believes that slaves are tied to their masters not only by tradition and economic necessity but also by "a misinterpretation of Islam" that teaches that slavery is not illegal but governed by religious law.

"[13]In 2010, Abeid was discharged from his duties as a Senior Adviser to the President of the National Commission for Human Rights in Mauritania for continuously voicing slavery issues.

[27] On 17 May 2016, the Supreme Court of Mauritania reached the decision to immediately release Abeid, along with fellow activist Brahim Bilal Ramdhan.

[28] In August 2018, Abeid was imprisoned on an "order from above", considered by many to be an attempt to prohibit his participation in the September parliamentary elections, in which he was running as an anti-slavery, opposition candidate.

Following his illegal detention and ascension to Parliament, he proclaimed: "I will do everything possible to demonstrate that slavery, racism and torture are set up as a system of management by a small entity around a very corrupt head of state."
