August 1, 1980 – Vigdís Finnbogadóttir is elected President of Iceland and becomes the world’s first democratically elected female head of state. Although the Icelandic presidency is largely a ceremonial position, Vigdís took an active role as an environmental activist and fought for Icelandic language and culture, acting as a cultural ambassador in promoting the country. She emphasized the role of small nations and hosted a crucial summit between the US President Ronald Reagan and Soviet leader Mikhail Gorbachev in 1986. She had as her motto: ‘Never let the women down’ and worked specifically to promote girls’ education. She was also aware of her role as a model for young women.
