Memoirs of the Twentieth Century[1] is an early work of speculative fiction by Irish writer Samuel Madden.

In his 1987 work Origins of Futuristic Fiction, Paul Alkon describes the book as the earliest in English literature to feature time travel, but notes that it does not explain how it was performed.

[4] In the 2008 book Physics of the Impossible, Michio Kaku calls the work arguably the first account of time travel in fiction.

In France, King Louis XIX[n 3] reigns but the French state is weak and he is controlled by his Jesuit prime minister.

The new regime pursued a liberal religious policy, and by 1997 Deism and Christianity had come to dominate, with Jesuit missionaries active and powerful.
