Bertha Meriton Gardiner was a British historical writer whose books were aimed at helping readers make sense of big turning points in European history. Sources available online confirm her authorship of works including The Struggle Against Absolute Monarchy, 1603–1688 and The French Revolution, 1789–1795.
Her writing focused on periods of conflict, reform, and revolution, especially in England and France. The surviving catalog and digitized-book records suggest she wrote for a broad audience rather than a narrowly academic one, presenting complex history in a readable way.
I could not confirm many personal biographical details from reliable sources in this search, beyond her identity as an author and the fact that she had died by 1925, so this overview stays close to what the available records support.
