In October 2014, indigenous women in Mexico won a landmark victory in their struggle for political rights.

It came after years of campaigning by Eufrosina Cruz Mendoza, a Zapotec woman who had been prevented from becoming mayor of her local community.

She believed a system of special laws, allowing indigenous communities to self-govern with their own traditions, had allowed men to maintain their patriarchal positions but left women marginalised.

After Eufrosina challenged those traditions, the Mexican Senate amended the constitution to ensure indigenous women had the right to vote and stand in elections. She speaks to Jacqueline Paine.

In 1944, as World War II was drawing to a close, the Mexican love song Besame Mucho crossed the Atlantic and became one of the most recognisable melodies of the post-war era. Its lyrics were daring for the time: an open plea for a passionate kiss.

The song had been written years earlier by Consuelo Velazquez, a young woman who composed romantic melodies for pleasure but kept her authorship a secret, fearing it could damage her career as a classical pianist.

When Consuelo’s secret got out, her song Bésame Mucho topped the charts in the US and became one of the most covered songs in Spanish, with versions by The Beatles, Elvis Presley and Frank Sinatra.

Stefania Gozzer speaks to her son, Mariano Rivera Velazquez, about his mother's unexpected worldwide success.
