Tanzania is one of the African countries with the highest rates of child marriage in the world – two out of every five girls marry before their 18th birthday with a prevalence rate of 37% nationwide, according to the country’s national demographic and health survey of 2015/16.

Rebeca Gyumi, in early 2016, filed a petition at the High Court to challenge the Tanzania Marriage Act which allowed girls as young as 14 to get married and won a landmark case that same year that raised the age of child marriage from 14 to 18.

Following the impact of her work, Gyumi was named the 2016 UNICEF Global Goals award winner for her work in advancing girls’ rights in Tanzania.

That same year, she was named 2016 Woman of the Year by New Africa Magazine.
