Pierre was born in
Villa Altagracia,
San Cristóbal, Dominican Republic, on July 4, 1963 to parents of Haitian origin (her mother migrated with a temporary work permit in 1957 but overstayed this permit, and her father entered the Dominican territory irregularly). One of twelve children, she was raised in a migrant worker camp called a
batey, where many of Haitian descent live. Her birth certificate lists her name as
Solain Pie, which Pierre "says is the result of an error by a government clerk." At the age of 14, she organized a five-day protest by sugar cane workers on one of the country's bateyes, which led to her being arrested. However, the protest attracted enough public attention that the workers' demands namely, to have their living quarters painted and be given better tools and pay raises were met. == Career ==
