Juliusz Słowacki (4 September 1809 – 3 April 1849) was a Polish Romantic poet. He is considered one of the "Three Bards" of Polish literature — a major figure in the Polish Romantic period, and the father of modern Polish drama. His works often feature elements of Slavic pagan traditions, Polish history, mysticism and orientalism. His style includes the employment of neologisms and irony. His primary genre was the drama, and secondly, lyric poetry. His most popular works include the dramas Kordian and Balladyna and the poem Beniowski.

Słowacki spent his youth in Stolen Lands, in Kremenets (Polish: Krzemieniec) and Vilnius (Polish: Wilno). He briefly worked for the government of the Kingdom of Poland. During the November 1830 Uprising, he was a courier for the Polish revolutionary government. When the uprising ended in defeat, he found himself abroad and thereafter, like many compatriots, lived the life of an émigré. He settled briefly in Paris, France, and later in Geneva, Switzerland. He also traveled through Italy, Greece and the Middle East. Eventually he returned to Paris, where he spent the last decade of his life. He briefly returned to Poland when another uprising broke out during the Spring of Nations (1848).

Słowacki was born on 4 September 1809 at Kremenets (Krzemieniec), Volhynia, formerly part of the Polish - Lithuanian Commonwealth, then in the Russian Empire, now in Ukraine. His father, Euzebiusz Słowacki, a Polish nobleman of the Leliwa coat of arms, was a professor of the history of literature, rhetoric, poetry and Polish language. He was a teacher at the Liceum Krzemienieckie (Krzemieniec Lycée) in Kremenets, and from 1811, he headed the academic department (katedra) of rhetoric and poetry at the Vilnius Imperial University in Vilnius (Wilno). He died in 1814, leaving Juliusz to be raised solely by his mother, Salomea z Januszewskich Słowacka, a noblewoman of disputed descent, either Jewish or Armenian. In 1818 she married a professor of medicine, August Bécu. She ran a literary salon, and young Juliusz was exposed to many influences there. It was there in 1822 that Słowacki, then only 13 years old, met Adam Mickiewicz, the first of the Three Bards of Polish literature. Two years later, in 1824, Mickiewicz was arrested and exiled by the Russian authorities for his involvement with the patriotic Philomaths society; Słowacki likely met with him on his final day in Wilno.

Słowacki was educated at the Liceum Krzemienieckie and later attended a Vilnius Imperial University preparatory gymnasium in Wilno. From 1825 to 1828 Słowacki studied law at the Vilnius Imperial University. His earliest surviving poems date to that period, although it is presumed he wrote some earlier, none of which have survived.

In 1829 he moved to Warsaw, where he found a job in the Congress Poland's Governmental Commission of Revenues and Treasury. In early 1830 he began his literary career, debuting with the novel Hugo, published in the periodical Melitele. That year, the November Uprising began, and Słowacki published several poems with patriotic and religious undertones. His Hymn, first published in Polak Sumienny ("The Conscientious Pole") on 4 December 1830, and other works such as Oda do Wolności (An Ode to Freedom) gained him much acclaim and was quickly reprinted several times.

In January 1831 he joined the diplomatic staff of the revolutionary Polish National Government, led by Prince Adam Jerzy Czartoryski. Initially he served as a copist. On 8 March he was sent on a courier mission to Dresden (although some sources say this was not an official mission, but Słowacki's private voyage). Many others left Warsaw around that time, in the aftermath of the battle of Olszynka Grochowska, and expected Russian advance on Warsaw. In Dresden Słowacki was well received by the local emigree Polish community, and even welcomed as the "bard of fighting Warsaw." In July, he volunteered to deliver messages from the National Government to its representatives in London and Paris, where he heard about the failure of the Uprising. Details of his mission (what letters he was carrying, and to whom) are not known.

Like many of his countrymen, Słowacki decided to stay in France as a political refugee. In 1832 he published his first collections of poems and his first two dramas (Mindowe and Maria Stuart). He also met Mickiewicz again; reportedly, Mickiewicz approached his younger colleague and shook his hand. However, Słowacki's poems, written in the 1820s, were unpopular among his Polish compatriots, as they failed to capture the sentiment of a people living under foreign occupation. Słowacki was also angered by Mickiewicz, who not only stole the limelight with his Księgi narodu polskiego i pielgrzymstwa polskiego (Books of the Polish nation and pilgrimage), but his part three of Dziady (1832) cast Słowacki's stepfather, professor Bécu, in the role of a villain. In a letter to his mother Słowacki wrote that immediately after reading that work he was ready to challenge Mickiewicz for a duel; that did not come to pass but from that moment on, Słowacki would see Mickiewicz as his main rival. Few days later, antagonized by worsening reception of his works among the Polish émigré community in Paris, including sharp criticism from Mickiewicz, Słowacki left on a trip to Geneva, Switzerland. The French authorities denied him the right to return to France as part of a larger program to rid the country of the potentially subversive Polish exiles who had settled there. From 1833 to 1836 he lived in Switzerland. A third volume of his poems, published in 1833 and containing works from the period of the Uprising, was far more nationalist in tone, and won more recognition in his homeland. At the same time, he wrote several works featuring romantic themes, and beautiful scenery, such as W Szwajcarii (In Switzerland), Rozłączenie (Separation), Stokrótki (Daisies) and Chmury (Clouds). In 1834 he published the drama Kordian, a romantic drama, illustrating the soul searching of the Polish people in the aftermath of the failed insurrection; this work is considered one of his best creations.

In 1836, Słowacki left Switzerland and embarked on a journey that started in Italy. In Rome he met and befriended Zygmunt Krasiński, the third of the Three Bards. Krasiński is also considered the first serious literary critic of Słowacki's work. Słowacki would dedicate several of his works, including Balladyna, to Krasiński. From Rome, Słowacki went to Naples and later, to Sorrento. In August he left for Greece (Corfu, Argos, Athens, Syros), Egypt (Alexandria, Cairo, El Arish) and the Middle East, including the Holy Land (Jerusalem, Bethlehem, Jericho, Nazareth) and neighboring territories (Damascus, Beirut). It was a journey Słowacki described in his epic poem Podróż do Ziemi Świętej z Neapolu ("Travel to the Holy Land from Naples"); his other works of that period inclucded the poem Ojciec zadżumionych (The Father of the Plague - stricken), Grób Agamemnon (Agammemnon's Grave), Rozmowa z piramidami (A talk with the pyramids), Anhelli and Listy poetyckie z Egiptu (Poetic Letters from Egypt). In June 1837 he returned to Italy, settling briefly in Florence, and moved back to Paris in December 1838.

In 1840 Mickiewicz was elected to the position of professor of Slavic literature at Collége de France; it was one of the events that cemented his position over Słowacki in the Polish émigré community. The rivalry between the two Bards for primacy would continue till the ends of lives. In 1841 Słowacki traveled briefly to Frankfurt, but Paris would become his main home till his death. In 1840 and 1841 he wrote two notable dramas: Mazepa, the only of his dramas that was put on stage during his lifetime, and Fantazy, published posthumously, well received by critics. Over the next few years Słowacki wrote and published many works, including Testament Mój (My Last Will), in which he described his faith that his works would endure after his death. Between 1841 and 1846, he published Beniowski, considered by some his best lyrical poetry. Starting as a story of a historical figure, it developed into a discussion of the poet's own life and opinions. In 1842 he joined the religious philosophical group, Koło Sprawy Bożej (Circle of God's Cause), led by Andrzej Towiański. This group included, among others, Mickiewicz. Towiański's influence is credited with a new, mystical current in Słowacki's works, seen in works such as the poem Beniowski and the drama Ksiądz Marek (Father Mark). Słowacki left the Circle a year later, in 1843.

In the summers of 1843 and 1844 Słowacki traveled to Pornic, a resort on the Atlantic coast in Brittany. It was there, in 1844, that he wrote Genezis z Ducha (Genesis from the Spirit). This work introduced his own philosophical system that would have a visible influence on his works in his last decade. Around 1839 Słowacki put his capital into the Parisian stock market. He was a shrewd investor who earned enough from the investments to dedicate his life to his literary career; he was also able to pay the costs of having his books published.

In the late 1840s Słowacki attached himself to a group of like minded young exiles, determined to return to Poland and win its independence. One of his friends was the pianist and composer Frédéric Chopin. Others included enthusiasts of his work, such as Zygmunt Szczęsny Feliński, Józef Alojzy Reitzenheim and Józef Komierowski. Despite poor health, when he heard about the events of the Spring of Nations, Słowacki traveled with some friends to Poznań, then under Prussian control, hoping to participate in the Wielkopolska Uprising of 1848. He addressed the National Committee (Komitet Narodowy) in Poznań on 27 April. "I tell you," he declared as the rebels faced military confrontation with the Prussian Army, "that the new age has dawned, the age of holy anarchy." But by 9 May, the revolt was crushed.

Arrested by the Prussian police, Słowacki was sent back to Paris. On his way there, he passed through Wrocław, where in mid-June he was reunited with his mother, whom he had not seen for almost twenty years. He returned to Paris in July 1848. His poem Papież Słowiański (The Slavic Pope), published in late 1848, gained new fame a century later when it seemed to foretell the 1978 ascent of Karol Wojtyła to the throne of St. Peter as Pope John Paul II. His final dramas (Zawisza Czarny, Samuel Zborowski), attempted to explain the history of Poland through Słowacki's genesic philosophy. In March 1849 Słowacki, his health failing, was visited three times by another Polish writer and poet, Cyprian Norwid, who later wrote about his visits in Czarne kwiaty (Black Flowers). Up to his final days, Słowacki was writing poetry; a day before his death he dictated passages of his final work, Król-Duch (King - Spirit). This grandiose, visionary - symbolic poem, "summary of the entire Romantic culture", Słowacki's masterpiece, weaving together Poland's history and its contemporary political and literary thought, was never finished.

Słowacki died in Paris on 3 April 1849 from tuberculosis, and on 5 April he was buried in the Montmartre Cemetery in Paris. He never married. Only about 30 people attended his funeral. Krasiński, although estranged from Słowacki in the last few years, wrote of the funeral:

Słowacki's tombstone at Montmartre was designed by his friend and executor of his last will, painter Charles Pétiniaud - Dubos; it did not weather the passage of time well however, and in 1851 a new, similar tombstone was put in place, this one designed by Polish sculptor Władysław Oleszczyński. In 1927 Słowacki's remains were moved to Wawel Cathedral in Poland, but an empty grave still remains at Montmartre.

Słowacki was a prolific writer; his collected works (Dzieła wszystkie) were published in 17 volumes. His legacy includes 25 dramas and 253 works of poetry. He wrote in many genres: dramas, lyrical poems, literary criticism, letters, journals and memoirs, fragments of two novels, and a political brochure; he was also a translator. His letters to his mother are among the finest letters in all Polish literature. Although the majority of his works were in Polish, he also tried his hand at several works in French language (Le roi de Landawa, Beatrice Cenci). Many of his works were published only posthumously, often under arbitrary titles, as Słowacki never named them himself. He also left notes on works that he never began or never completed. Słowacki is also considered the father of modern Polish drama.

Polish historian of literature Włodzimierz Szturc divides Słowacki's work into four periods: Wolter's circle (pseudoclassicism), Christian ethic, Towiański's ethic and genesic ethic. Other scholars offer slighlty different periodizations; for example dividing his works into a classical period, a Swiss period, a Parisian period and a genesis period. Jarosław Ławski combines Towiański's period with the genesic ones, speaking of a "mystical" period. Overall, Słowacki's early work was influenced by Byron and Shakespeare, and included works that was often historical in nature, like (as in Maria Stuart or Mindowe), or exotic, Oriental locales (as in Arab). His work took on a more patriotictone following the failed November Insurrection of 1830 – 1831. His final works are heavy in mystical and philosophical undertones. In the 1840s he developed his own philosophy, or mystical system, with works such as Król-Duch and Genesis z Ducha being an exposition of his philosophical ideas ("genesic philosophy") according to which the material world is an expression of an ever - improving spirit capable of progression (transmigration) into constantly newer forms. As Ławski notes, his philosophical works can transcend clear boundaries of simple literary genres.

Słowacki's works, situated in the period of romanticism in Poland, contain rich and inventive vocabulary, including many neologisms. They use fantasy, mysticism and symbolism and feature themes related to Poland's history, essence of Polishness, and relation to a larger universe. Ławski, enumerating the main characteristics of Słowacki's writings, notes first that he was a "creationist", in the sense of creating new meanings and words (many of his characters bear names he invented himself, such as Kordian). Second, he notes that Słowacki was not only inspired by works of others, from poets and writers to scholars and philosophers, but that his texts were often a masterful, ironic - grotesque polemic with other creators. For example, Słowacki was so impressed by Antoni Malczewski's Maria that he wrote a sequel to it, Jan Bielecki. Likewise, Kordian is seen as building on William Shakespeare's Hamlet, and as Słowacki's response to Mickiewicz's Dziady. This Ławski calls "ivy-like imagination", comparing Słowacki's approach to that of an ivy, growing around works of others and reshaping them into new forms in a sophisticated literary game. Third, Słowacki was a master of irony; he used it not only on others, but on himself, and even on irony itself - the "irony of irony". He is thus seen as one of the forerunners to the literature of irony and grotesque, popular in the 20th century.

After his death, Słowacki acquired the reputation of a national prophet. He is now considered to be one of the "Three Bards" (wieszczs) of Polish literature.

Słowacki was not a very popular figure in Paris, nor among his contemporaries. He wrote many dramas, which can be seen as his favorite genre, yet he was a playwright who never saw any of his work performed on stage (only Mazepa was staged during his lifetime, and not in his presence). His works, written in Polish, dense with Slavic myths, philosophy and symbols, were difficult to translate to other languages. Słowacki's unpopularity among other Polish émigrés can be attributed to his unwillingness to pander to contemporary tastes; and in particular, his refusal to comfort his compatriots, shaken by the loss of Polish statehood and the failure of the November Uprising. Though a patriot as well, Słowacki's ironic and sometimes pessimistic attitude was not appreciated by his contemporaries, nor was his denial of Polish uniqueness. Whereas Mickiewicz followed the Messianic tradition and in Konrad suggested Poland's fate was in the hands of God, Słowacki's Kordian questioned whether his country was not a plaything of Satan instead. In Anhelli, Słowacki's describes the tragic fate of Polish exiles in Siberia, portraying a rather gloomy vision of Poland's destiny; the same topic was taken by Mickiewicz in the Books of the Polish Nation and of the Polish Pilgrimage as a call for Polish people to spread hope and spirituality across Europe. While a small circle of his friends talked about his wit, perseverance and inspiration, in popular memory he was a "sickly man of weak character", egocentric, bitter due to his failed rivalry with Mickiewicz. Mickiewicz himself wrote of Słowacki's work as a "beautiful church, but without God inside".

After his death, however, Słowacki gained a cult-like status in Poland; in particular, in the cultural center of Kraków. Several obituaries and longer articles appeared in the Polish press upon Słowacki's death. His works, many of them published posthumously for the first time, found growing acceptance among a new generation; an 1868 work noted that "Słowacki took the fancy of the Polish youth. He was its singer, its spiritual leader in the full meaning of the term". Through undoubtedly a poet of the romantic era, he was increasingly popular among the positivists and the authors of the Young Poland period in the late 1800s and early 1900s. His works were popularized by other writers, such as Adam Asnyk and Michał Bałucki, and his dramas were shown in theaters. He became a major literary figure for the new generation of Polish writers. He also became respected abroad; a 1902 English language book edited by Charles Dudley Warner noted that "the splendid exuberance of his thought and fancy ranks him among the great poets of the nineteenth century".

In 1927, some eight years after Poland regained her independence, the Polish government arranged for Słowacki's remains be moved to Wawel Cathedral in Kraków. He was interred in the Crypt of National Bards, together with Mickiewicz. His burial in the Wawel Cathedral was a controversial issue, as many of his works were considered heretical by Polish Catholic Church officials. It took almost two decades and the backing of Józef Piłsudski, for whom Słowacki was a favorite poet, to get the Church's acceptance for interring Słowacki's remains in the Wawel Cathedral. During the 1927 ceremony, Piłsudski spoke of Słowacki:

Several streets and schools in modern Poland bear the name of Juliusz Słowacki. Three parks are dedicated to him: in Bielsko - Biała, in Łódź and in Wrocław. There are several monuments of Juliusz Słowacki, including ones in Warsaw (2001) and Wrocław (1984). Among the most notable landmarks bearing his name is the Juliusz Słowacki Theatre in Kraków.

In 2004, a Juliusz Slowacki Museum in Kremenets, Ukraine, was opened in his family's former manor house. In 2009 the Polish Sejm (parliament) declared that year, the two-hundredth anniversary of Słowacki's birth, to be the Year of Juliusz Słowacki.
