Charles Pierre Péguy (French: [?a?l pegi]; 7 January 1873 – 5 September 1914) was a noted 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.
