The Swiatopolk-Czetwertynski's are a Polish ducal family, descending from Rurik, leader of the Varangian tribes, originating from Scandinavia, who colonised, in the 9th century, vast lands comprised between the Baltic and the Black seas, establishing what is known as the "RUS" kingdoms.
The eldest and most important were Novgorod and Kiev.


One of the most famous princes belonging to the Rurik family was St Wladimir, Grand Duke of Kiew, who converted to orthodoxy, a decision that had great historical consequences.

The Czetwertynskis descend directly from Prince Swiatopolk Michaïl Isiaslawovitch (Known as Swiatopolk II :1050 - 1113) one of the successors of Wladimir on the throne Kiev, who's daughter Eudoxia was married to prince Mieczyslaw of Poland (d. 1089).

The Swiatopolks couldn't keep the crown of Kiev. They retired to their estates in Volhynia (located in the western part of today's Ukraine), where they held the title of princes of Pinsk and Torow. Their seat was the Stara Czetwertnia castle, on the Styr river. In 1387, prince Aleksander Swiatopolk took the name of Czetwertynski after the name of this estate which according to an old legend once extendend over one forth of the surface comprised between the river Styr and the hill range southwards, near the city of Lutsk(Czetwertynski means "one forth" or "quarter").


The Gotha Almanach gives the following description (in French) :

( extrait de l’édition de 1886 )


"La famille Swiatopolk-Czetwertynski par ses armes (le St.Georges) qui sont aussi celles du Grand Duché de Moscou ainsi que par l’évidence historique, prouve sa descendance de Rurik, fondateur de la première dynastie de Russie d’origine varègue (provenant de Scandinavie) à la fin du 9ème siècle.
Elle a pour ancêtre Swiatopolk I, neveu et fils adoptif de Saint Wladimir, fondateur du Grand-Duché de Kiew, auquel il succèda sur le trône
Elle a toujours gardé le nom de Swiatopolk (ou Swiatopelk selon l’orthographe polonaise) auquel a été joint, à la fin du 14ème siècle (1387) celui de Czetwertynski, provenant de la terre de Czetwertnia en Ukraine occidentale.
Princes de Turow et de Pinsk, les Swiatopolk-Czetwertynski sont la seule famille d’origine dynastique qui, depuis le moyen-âge, se fixa dans les provinces Ruthènes, incorporées à la Pologne. Ils remplirent au Royaume de Pologne puis dans la République polono-lituanienne de grandes charges de l’Etat de même que, plus tard, certains d’entr’eux, en Russie.
Le titre de Princes russes originaires leur fut confirmé par la chambre héraldique de St-Pétersbourg en 1843"


The entry in the Encyclopedia Britannica :


CZETWERTYNSKI (Swiatopelk-Czetwertynski), a polish ducal family descended from the Ruthenian branch of the Rurik dynasty, the descendants of Svyatopolk II Izyaslavich, grand duke of Kiev (d.1113).

Their seat was the Stara Czetwertnia castle on the Styr river in Volhynia.

In the 17th century they supported the Orthodox Church against the union with the Roman Catholic Church. One of the family, Grzegorz Gedeon (d.1690), was Orthodox metropolitan of Kiev, while Stefan Sylwester (d.1727) was Orthodox bishop of Mogilev.

From the end of the 17th century the main branch turned to Roman Catohilicism and began to consider themselves as Poles; the younger branch remained Orthodox and became Russian. During the 17th and 18th centuries several members of the elder branch held senatorial office in Poland. The most renowned was the notorious Antoni Stanislaw (1784-94), castellan of Przemysl, who sold his services to Russia and was the last leader of the confederation of Targowica, which opposed reforms of state.

During the Kosciuszko insurrection he was hanged as a traitor on June 28, 1794. Several of the Czetwertynskis, however, took part in the national insurrections of 1830 and 1863. The most distinguished was Wlodzimierz (1837-1918), a collector and philanthropist. His son Seweryn Franciszek Kalikst (1873-1945) was a member of the Russian duma (1906) and of the Polish sejm (1922-28). Arrested by the Germans in World War II, he was sent to a concentration camp in 1943, and freed by the Allies in 1945. He died soon afterward in Edinburgh, Scotland.


RURIK DYNASTY HISTORY (anonymous source):

The Rurik Dynasty began in ca. 862 when the Varangian prince Rurik was asked to rule over the city of Novgorod. His descendants controlled Kiev Rus' and, later, Muscovy {Moscow} until 1598.

Rus refers to the ancient peoples who inhabited, what we now know as, Russia. Historians believe the Rus were a group of Vikings known as Varangians who migrated south from the Baltics and mingled with the eastern Slavic peoples of the region.

This theory is supported by the only credible, known document covering the history of the time. The Primary Russian Chronicle; a history written in the 12 th century by the Orthodox monk Nestor, regarding the years 852-1110; states that the Rus were Norman and invited by the people of Novgorod to come and govern their city. The reason for this request was many years of unresolved feuds between the various Slavic clans.

Other historians, primarily Soviet scholars, believe the Rus was a Slavic tribe living on the Ros {Rus} River, which, for a brief time, was under Varangian control. They denounce the credibility of The Primary Russian Chronicle.

Either way, the Rus, most probably, became a combined group of Varangian Vikings and Eastern Slavs. There is no doubt that the center of the Rus culture was Kyiv {Kiev}, in modern day Ukraine.

Rurik was succeeded by Oleg {d. 912} who conquered Kiev in ca. 882. Oleg established a lucrative trade route from Novgorod to the Black Sea. Oleg was succeeded by Igor who, legend has it, was Rurik's son. Igor ruled from Kiev from 912-945.


Upon his death, his wife, the regent of Kiev; Olga; and their son, Svyatoslav, reigned till 969 and 972, repectfully. Svyatoslav's son, Yaropolk, ruled without much note, till 980.In 956, another son was born to Svyatoslav. His name was Vladimir who inherited the crown in 980, ruling until his death in 1015.

Vladimir composed the first law code for Kiev Rus. He unified his realm by making it a confederation with key cities in each region ruled by his sons. The princes were to move from city to city, working their way up to becoming prince of Kiev. The system created frequent civil conflicts as the people of the key cities, from time to time, did not like the prince assigned to rule over them.


Vladimir is best known for introducing and establishing Orthodox Christianity in Kiev.Vladimir's grandmother, Olga, received Christianity and was Baptized in Constantinople in 957. Her son, Svyatoslav, thought her foolish and rejected any attempts to convert him. His son, Vladimir, followed Olga's lead and embraced Christianity, was Baptized and married Anna, the sister of the Byzantine emperor, in ca. 988. Vladimir's son, Yaroslav the Wise {1019-1054}, advocated translations of the Bible into the various vernaculars and the building of churches and monasteries. The first monastery was Kyiv Pechersk Lavra, {The Monastery of the Caves} established in 1051 and operational to this day. Aside from its historical significance, this monastery is unique in that most of it is contained in underground caves.

How did Christianity, specifically the Byzantine Orthodox, form the foundation of the later Russian Orthodox Church? The Primary Russian Chronicle tells the story. Vladimir wanted to know which of the world religions was the true one. So, he sent a group of loyal subjects to the Muslims in Volga. They reported back to Vladimir that they thought these people were possessed.


Next, they traveled to Germany and Rome. The Church of Rome was more to their liking, however, they found it to be without much spiritual beauty. Lastly, they visited Constantinople, the center of Byzantium. After attending a Divine Liturgy, the travelers reported, "We knew not whether we were in heaven or on earth, for surely there is no such splendour or beauty anywhere upon earth. . . God dwells there among humans." It is typical of Byzantine and, as a result, Russian Orthodox Christianity to stress the beauty of the spiritual world and express this in their liturgy and holy places. In fact, their Liturgy is designed to reflect heaven on earth. Thus, Vladimir embraced Byzantine Orthodoxy and introduced it to Kiev Rus in ca. 988. This date is also known as the Baptism of Russia.Vladimir was determined to convert his realm. He imported priests, relics, Byzantine ikons and a patriarch was appointed. Huge Baptisms were conducted in the rivers, a system of tithes established and the pagan idol, Perun, destroyed. Perun, the greatest of the Slavic gods, was the god of the world and portrayed with thunderbolts and flying across the sky. As in many other cases when Christianity replaces an ancient pagan religion, Perun's image was replaced with that of the prophet Elijah, seen ascending to the heavens in a chariot of fire.The idol of Perun was, ceremoniously, thrown off a hill above Kiev.

Probably the most commendable aspect of Vladimir's conversion was his personal application of Christian ethics. He is credited with having, by far, the most extensive system of social services of any medieval ruler. For example, whenever there was a feast at the royal court in Kiev, Vladimir had food distributed throughout the land to the poor and ill. This philosophy was carried on by later Kievan rulers. Vladimir Monomachos {1113-1125} wrote to his sons, "above all things forget not the poor and support them to the extent of your means. Give to the orphan, protect the widow and permit the mighty to destroy no man."


Vladimir's law code was heavily influenced by Byzantine and Christian principles. It was a code based on mercy, forgiveness and restoration of the individual. It strictly prohibited the death penalty, torture or mutilation which was used excessively in Byzantium.

Another story, which reflects Vladimir's conviction to his faith, involves his sons; Boris and Gleb. Vladimir died in 1015. The eldest son, Svyatopolk {the Damned; 1015-1019}, tried to take over the cities or principalities of his younger brothers, Boris and Gleb. Following Gospel teaching, the younger brothers refused to go to war against their elder sibling. They were both murdered by Svyatopolk's soldiers. The Russian Church considers the brothers' innocent blood and sacrifice, for the sake of peace, in keeping with the example set forth by Christ. As a result, they were canonized, as was Vladimir.
