Mary Robinson didn't just win the presidency in 1990, she blew the dusty doors off Áras an Uachtaráin.

That win was a seismic day for Ireland - we had our first woman president, and Ireland was on the cusp of great change, culturally, socially and economically.

Mná na hÉireann finally had a voice.

In this episode of Think You Know...The Presidents?, presenters Lise Hand and Flor Mac Carthy get to grips with their own 'girl crush' as they recall Robinson's rocky road to the Áras, when she encountered sexism and misogyny along the campaign trail.

She also paved the way for her female successor, who between them shared 21 years as Ireland's heads of state.
