Charles Péguy, French poet and philosopher (b. 1873)
Charles Pierre Péguy (French: [ʃaʁl peɡi]; 7 January 1873 – 5 September 1914) was a French poet, essayist, and editor. His two main philosophies were socialism and nationalism, but by 1908 at the latest, after years of uneasy agnosticism, he had become a believing but non-practicing Roman Catholic.

From that time, Catholicism strongly influenced his works.
