The first woman to serve as Prime Minister of a country was Sirimavo Bandaranaike of Ceylon (now Sri Lanka). She took office in 1960 and became the world's first female head of government. Her leadership marked a significant milestone in the political landscape, challenging traditional gender roles and advancing women's representation in politics. Bandaranaike's tenure focused on social reform, education, and economic development, and she served multiple terms throughout the 1960s and 1970s. Her influence extended beyond Sri Lanka, inspiring future generations of women leaders worldwide.
