He fought in the foreign campaigns at Lützen, Bautzen, Pirna, Kulm, and Leipzig, and took part in the taking of Paris.[6](https://imha.ru/1144543426-chaadaev-petr-yakovlevich.html) • [7](https://rbsmp.uz-rf.com/publications/istoriya_i_bolezni/nikolay_larinskii_chaadaev) • [3](https://um.mos.ru/personalities/chaadaev/)\n\nHe is recorded with the Order of St. Anna 3rd class or 4th class for bravery in battle, and with the Kulm Cross awarded at Kulm.[6](https://imha.ru/1144543426-chaadaev-petr-yakovlevich.html) • [7](https://rbsmp.uz-rf.com/publications/istoriya_i_bolezni/nikolay_larinskii_chaadaev) He was also awarded the Prussian Iron Cross.[3](https://um.mos.ru/personalities/chaadaev/) • [8](https://etd.ohiolink.edu/acprod/odb_etd/ws/send_file/send?accession=miami1501257762960849&disposition=inline)\n\nHis nickname was \"the handsome Chaadaev,\" and he was expected to be made flügel-adjutant to [Alexander I](https://www.edgepedia.org/alexander-i).[7](https://rbsmp.uz-rf.com/publications/istoriya_i_bolezni/nikolay_larinskii_chaadaev)\n\nThe Semyonovsky regiment mutinied during Chaadaev's stay in the Imperial capital, prompting his resignation from the military under uncertain circumstances; in an 1826 interview Chaadaev attributed it to \"matters of the household.\"[8](https://etd.ohiolink.edu/acprod/odb_etd/ws/send_file/send?accession=miami1501257762960849&disposition=inline)\n\n## The Philosophical Letters and the government's verdict\n\nFrom 1823 to 1826 Chaadaev traveled in England, France, Italy, Switzerland, and Germany; after his return to Russia, secret police surveillance was established over him.[6](https://imha.ru/1144543426-chaadaev-petr-yakovlevich.html) • [1](https://www.britannica.com/biography/Pyotr-Yakovlevich-Chaadayev) According to [Alexandre Koyré](https://www.edgepedia.org/alexandre-koyre)'s study in *Koncept: Philosophy, Religion, Culture*, he wrote eight *Philosophical Letters* in French, using the conceptual apparatus of [German philosophy](https://www.edgepedia.org/german-philosophy), in particular the ideas of Schelling, with whom he was personally acquainted.[11](https://concept.mgimo.ru/jour/article/view/519) \n\nThe letter's argument was a sweeping indictment of Russia, in the author's own words an \"accusatory act.\" Russia, Chaadaev held, had received its religion and culture from [Byzantium](https://www.edgepedia.org/byzantium), which stood outside both East and West, and had therefore remained outside the history of world civilization; he wrote that \"not a single great truth has come from our midst.\" Against Orthodox isolationism he set Roman Catholicism and its idea of universality, advocating assimilation of western European culture.[9](http://www.historycenter.ru/info/literenc1962-1978/ke8-4171.htm) • [4](http://hrono.ru/biograf/bio_ch/chaadaev_petr03.php) • [1](https://www.britannica.com/biography/Pyotr-Yakovlevich-Chaadayev)\n\nThe first letter had circulated informally for years before its publication in Russian in the review *[Teleskop](https://www.edgepedia.org/teleskop)* in 1836. The effect was immediate. [Nicholas I](https://www.edgepedia.org/nicholas-i), on reading the article, wrote: \"Having read the article, I find its contents a mixture of daring nonsense worthy of a madman.\" By supreme command Chaadaev was officially declared insane and placed under house arrest with medical supervision, though left at liberty; *Teleskop* was closed, its editor N. I. Nadezhdin exiled to Ust-Sysolsk, and the censor A. V. Boldyrev dismissed.[1](https://www.britannica.com/biography/Pyotr-Yakovlevich-Chaadayev) • [4](http://hrono.ru/biograf/bio_ch/chaadaev_petr03.php) • [6](https://imha.ru/1144543426-chaadaev-petr-yakovlevich.html) • [11](https://concept.mgimo.ru/jour/article/view/519)\n\nChaadaev answered with the *Apology of a Madman*. The scholar Alexandre Koyré, however, disputes the view that the *Apology* marked a substantial change of view or a recantation of his sharply critical assessment of Russian history as a \"gap in the spiritual world-order.\"[11](https://concept.mgimo.ru/jour/article/view/519) • [4](http://hrono.ru/biograf/bio_ch/chaadaev_petr03.php)\n\nThe humiliating supervision of a police doctor was lifted on 30 October 1837, by a resolution of Nicholas I: \"to free from medical supervision on condition that he dare write nothing.\"[3](https://um.mos.ru/personalities/chaadaev/) • [10](http://sv-scena.ru/Buki/Sto-vyelikikh-myslityelyeyi.61.html)\n\n## Political influence\n\nHis influence on the state was indirect but lasting: he was the first Russian thinker for whom Russia itself became a philosophical problem, initiating the Russian tradition of debating the meaning of Russian history, national identity, and the country's future path.[12](https://www.rep.routledge.com/articles/biographical/chaadaev-petr-iakovlevich-1794-1856/v-1/sections/e007aentry) His ideas precipitated the controversy between the Slavophiles and the Westernizers, the first serious theoretical dispute about Russia's place in world history.[1](https://www.britannica.com/biography/Pyotr-Yakovlevich-Chaadayev) • [11](https://concept.mgimo.ru/jour/article/view/519) His pessimistic view of Russia provoked a strong reaction among Russian Romantic conservatives, who argued that the West, not Russia, represented atomistic disintegration.[12](https://www.rep.routledge.com/articles/biographical/chaadaev-petr-iakovlevich-1794-1856/v-1/sections/e007aentry)\n\n## Death and assessment\n\nAfter the [Crimean War](https://www.edgepedia.org/crimean-war) of 1853–56, seeing no improvement in Russia's position, Chaadaev thought of suicide. He died of pneumonia on 14 (26) April 1856, leaving his material affairs in complete disorder.[4](http://hrono.ru/biograf/bio_ch/chaadaev_petr03.php) • [3](https://um.mos.ru/personalities/chaadaev/) • [10](http://sv-scena.ru/Buki/Sto-vyelikikh-myslityelyeyi.61.html)\n\nHistorians have assessed him in markedly different ways: as a militant Westernizer, as a mystic and conservative, as a figure of the liberation movement, and as a purely religious thinker. Koyré challenges the usual label of refined Westernizer, showing that Chaadaev accepted some fundamental positions of I. V. Kireevsky and other Slavophiles, including religious ones, while interpreting them in his own way. In any assessment, he played a significant role in the development of Russian social thought.[4](http://hrono.ru/biograf/bio_ch/chaadaev_petr03.php) • [11](https://concept.mgimo.ru/jour/article/view/519) • [12](https://www.rep.routledge.com/articles/biographical/chaadaev-petr-iakovlevich-1794-1856/v-1/sections/e007aentry)\n\n## Legacy\n\nOf the eight letters, only the first was published in Russia in Chaadaev's lifetime; the sixth and seventh first appeared in *Voprosy filosofii i psikhologii* in 1906, and letters 2–5 and 8 only in 1935, in *Literaturnoe nasledstvo*, vols. 22–24.[9](http://www.historycenter.ru/info/literenc1962-1978/ke8-4171.htm) The question of Russia's relation to the West that he framed remains the organizing question of the Slavophile–Westernizer tradition he helped create.[12](https://www.rep.routledge.com/articles/biographical/chaadaev-petr-iakovlevich-1794-1856/v-1/sections/e007aentry)\n\n## References\n\n1.
