The French Revolution was a series of political and social upheavals in the late 18th century. This was the First Doctor's favourite period of Earth history: "all the turbulence of the age crammed into five years in one tiny country," as he put it. (PROSE: The Man in the Velvet Mask) It was an age which he visited on several occasions.
Revolutionary-era France was the site of the First Doctor and Susan Foreman's first-ever visit to Earth. (PROSE: Just War) Later, while attending Coal Hill School in 1963, Barbara Wright lent Susan a book called The French Revolution, in which Susan noted several historical inaccuracies. (TV: An Unearthly Child)
The Doctor and Susan visited Revolutionary-era France again, specifically July 1794, this time with Ian Chesterton and Barbara Wright accompanying them, not long after departing 1963. (TV: The Reign of Terror)
The Doctor and Dodo Chaplet later visited an alternate timeline, in which the Revolution continued longer than it did in N-Space. (PROSE: The Man in the Velvet Mask)
