Congratulations poured in from around the world Monday after Claudia Sheinbaum was elected Mexico’s first woman president, sparking hope for change in a country where gender-based violence has long been rife.

Flag-waving supporters sang and danced to mariachi music late into the night after the former Mexico City mayor won Sunday’s election by a landslide, the magnitude of which spooked financial markets.

Addressing cheering crowds, the 61-year-old ruling party candidate thanked the “millions of Mexican women and men who decided to vote for us on this historic day.”

Maria Fernanda Vela, 27, said it was “an inspiration that in such a male chauvinist country, a woman has taken the top job. It fills your heart with pride.”

US President Joe Biden welcomed Sheinbaum’s “historic election” and said he looked forward to working with her “in the spirit of partnership and friendship.”

Canadian Prime Minister Justin Trudeau, another key North American ally, also offered congratulations and said he was ready to work closely with Sheinbaum to further strengthen relations.

Brazilian President Luiz Inacio Lula da Silva, a fellow leftist, hailed a “victory for democracy” and vowed to deepen economic ties between Latin America’s two biggest economies.
