The tried and tested 'On This Day in History' format has elevated the stories of many people and their impact on the wider world. However, of those considered noteworthy by the Establishment, just a fraction are women. But this is not the whole story - not by half. Our past is full of influential women, many of whom have been unfairly confined to the margins of history. Politicians, troublemakers, explorers, artists, writers, scientists and even the odd murderer; these women have shaped society around the globe. From Beyoncé to Doria Shafik, Queen Elizabeth I to Lillian Bilocca, On This Day She sets out to redress this imbalance and give voice to both those already deemed female icons, alongside others whom the history books have failed to include: the good, the bad and everything in between - this is a record of human existence at its most authentic.
