Diane Rwigara, a human right activist, had once hoped to run for the Rwandan presidency, but her campaign was short-lived.

She was jailed and charged with fraud and inciting insurrection. In December, Rwigara and her mother, Adeline, were acquitted of all charges.

"We find that the prosecution charges do not have a basis and find Diane Rwigara and Adeline Rwigara not guilty on all charges," the three-judge verdict read, according to local news website The East African.

Her presidential bid: She was the sole female challenger in the presidential election, which the incumbent, Paul Kagame, won with almost 99% of the vote. She was also a fierce critic of Kagame.

She launched her election bid three months ahead of the August 2017 vote. Just days after she announced her plan to run for office, nude photos — allegedly of her — were posted online. Rwigara said the images were digitally altered and used by the government to discredit her. A spokesperson for Kagame's party at the time denied to CNN having anything to do with the photos.

The disqualification: Rwigara was eventually disqualified by electoral authorities who said she falsified signatures that she needed for her bid to qualify and accused her of submitting the names of dead people. Rwigara then launched an activist group called the People Salvation Movement to "encourage Rwandans to hold their government accountable," but was soon arrested on charges of inciting insurrection against the government and fraud.

A year in prison: The Rwigaras spent a year in a Kigali prison before they were released on bail in October.

Their case had alarmed human rights activists, who argued that all the charges were politically motivated and highlighted a lack of political and social freedom under Kagame, who has been president since 2000 and long an influential figure in Rwanda's modern history.
