South African President Cyril Ramaphosa urged men to unite against rape and sexual assault in the country, calling it a "national crisis".
Women were raped and killed on a continuous basis and the time had come to end gender violence, he said.
He made his passionate request as he launched an electoral manifesto for the African National Congress.
Approximately 40,000 rapes are reported each year, even if they are thought to be only a fraction of the royal total.
The president asked the men in the Durban stadium, where tens of thousands of supporters attended his speech, to stand up to show their condemnation.

"We have made tremendous progress in improving the position of women in society … However, gender violence is a national crisis that we are determined to end, so that all South African women and girls they can live in peace, security and dignity, "he said.
"Women's emancipation requires a change in the attitudes and material conditions that perpetuate the oppression and marginalization of women."
He outlined a series of measures to achieve this, including more stringent sentences for perpetrators and "better qualified" police and judicial authorities to improve the capacity to investigate and prosecute all crimes.
