The history of Christianity in Poland started in the reign of Mieszko I of Poland who was baptised in 966.
Gallus Anonymus recorded a story about "two strangers" [1] who visited the home of Piast, the legendary forefather of the Polish royal family, after Prince Popiel had ill-received them. [2] [3] Piast was celebrating the first haircut of his son, Siemowit, and the two visitors blessed Siemowit and foretold his family's emergence. [2] [4] In Polish historiography, the two wanderers have been identified as Irish monks or Moravian missionaries, but nothing proves the validity of these theories. [2] [5]
According to the Life of St Methodius, Methodius suggested a chieftain of the Vistulans —a Slavic tribe inhabiting the region along the upper courses of the river Vistula —that he should voluntarily receive baptism in his own land otherwise he would be baptized "as a prisoner in a foreign land". [6] [7] Historian A. P. Vlasto writes that the holy man's prophecy was fulfilled after the chieftain was forced to accept the suzerainty of Moravia or was captured. [8] Inscriptions on two fragmentary ceramic objects unearthed at Podebłocie have been interpreted as the abbreviation of the Greek text "Iesus Chrestos Nika" by Tadeusz Wasilewski and other scholars, but their view has not been universally accepted. [5] According to Przemysław Urbańczyk, no archaeological evidence of Christian communities in Poland before the 960s has been presented. [5]
Mieszko I —who was Siemowit's great-grandson, according to Gallus Anonymus—was the first Polish ruler known from contemporaneous sources. [9] In an attempt to enter into an alliance with Boleslaus I, Duke of Bohemia, he decided to marry the Duke's Christian daughter, Dobrava in 964 or 965. [10] [11] [12] According to the nearly contemporaneous Thietmar of Merseburg, Dobrava persuaded her husband to convert Christianity one or three years later. [13] His conversion, known as the baptism of Poland, was a milestone even in the Polish history.
Doubravka of Bohemia, Dobrawa was a Bohemian princess of the Přemyslid dynasty and by marriage Duchess of the Polans.
Mieszko I was the first ruler of Poland and the founder of the first independent Polish state, Civitas Schinesghe also known as the Duchy of Poland. His reign stretched from 960 to his death and he was a member of the Piast dynasty, a son of Siemomysł and a grandson of Lestek. He was the father of Bolesław I the Brave and of Gunhild of Wenden. Most sources identify Mieszko I as the father of Sigrid the Haughty, a Scandinavian queen, the grandfather of Canute the Great and the great-grandfather of Gunhilda of Denmark, Canute the Great's daughter and wife of Henry III, Holy Roman Emperor.
Bolesław I the Brave, less often known as Bolesław the Great, was Duke of Poland from 992 to 1025, and the first King of Poland in 1025. He was also Duke of Bohemia between 1003 and 1004 as Boleslaus IV. A member of the ancient Piast dynasty, Bolesław was a capable monarch and a strong mediator in Central European affairs. He continued to proselytise Western Christianity among his subjects and raised Poland to the rank of a kingdom, thus becoming the first Polish ruler to hold the title of rex, Latin for king.
Oda of Haldensleben was Duchess of the Polans by marriage to Mieszko I of Poland.
Great Moravia, or simply Moravia, was the first major state that was predominantly West Slavic to emerge in the area of Central Europe, possibly including territories which are today part of the Czech Republic, Slovakia, Hungary, Austria, Germany, Poland, Romania, Croatia, Serbia and Ukraine. The formations preceding it in these territories were the Samo's tribal union and the Pannonian Avar state.
The Peace of Bautzen was a treaty concluded on 30 January 1018, between Holy Roman Emperor Henry II and Bolesław I of Poland which ended a series of Polish-German wars over the control of Lusatia and Upper Lusatia as well as Bohemia, Moravia and Slovakia.
Vladivoj was Duke of Bohemia from 1002 until his death.
Vladislaus I was Duke of Bohemia from 1109 to 1117 and from 1120 until his death.
Ajtony, Ahtum or Achtum was an early-11th-century ruler in the territory now known as Banat in present Romania and Serbia. His primary source is the Long Life of Saint Gerard, a 14th-century hagiography. Ajtony was a powerful ruler who owned many horses, cattle and sheep and was baptised according to the Orthodox rite in Vidin. He taxed salt which was transferred to King Stephen I of Hungary on the Mureș River. The king sent Csanád, Ajtony's former commander-in-chief, against him at the head of a large army. Csanád defeated and killed Ajtony, occupying his realm. In the territory, at least one county and a Roman Catholic diocese were established.
Radogost is, according to medieval chroniclers, the god of the Polabian Slavs, whose temple was located in Rethra. In modern scientific literature, however, the dominant view is that Radogost is a local nickname or a local alternative name of the solar god Svarozhits, who, according to earlier sources, was the chief god of Rethra. Some researchers also believe that the name of the town, where Svarozhits was the main deity, was mistakenly taken for a theonym. A popular local legend in the Czech Republic is related to Radogost.
The Principality of Nitra, also known as the Duchy of Nitra, was a West Slavic polity encompassing a group of settlements that developed in the 9th century around Nitra, in present-day Slovakia. Its history remains uncertain because of a lack of contemporary sources. The territory's status is subject to scholarly debate: some modern historians describe it as an independent polity that was annexed either around 833 or 870 by the Principality of Moravia, while others say that it was under the influence of the neighbouring West Slavs from Moravia from its inception.
The pagan reaction in Poland was a series of events in the Kingdom of Poland in the 1030s that culminated in a popular uprising or rebellion, or possibly a series of these, that destabilized the Kingdom of Poland.
Wincenty of Kielcza was a Polish canon, poet, and composer, working in Kraków and writing in Latin. He was a member of the Dominican Order.

The German–Polish War consisted of a series of struggles in 1003–1018, between the Ottonian king Henry II of Germany and the Polish Piast ruler Bolesław I the Brave. The locus of conflict was the control of Lusatia, Upper Lusatia, as well as Bohemia, Moravia and Slovakia. The fighting ended with the Peace of Bautzen in 1018, which left Lusatia and Upper Lusatia as a fief of Poland, and Bohemia became a duchy in the Holy Roman Empire.
The udvornici, also udvarniks or royal serving people, was a class of half-free people who were obliged to provide well-specified services to the royal court in the medieval Kingdom of Hungary. They seem to have been descended from the Slavic population which was subjugated during the Hungarian conquest of the Carpathian Basin. Word udvornici is derived from slavic "U dvora", meaning "at/near the (royal) court". Their lord was the monarch, but they were administered by the Palatine.
Alternative theories of the location of Great Moravia propose that the core territory of "Great Moravia", a 9th-century Slavic polity, was not located in the region of the northern Morava River. Moravia emerged after the fall of the Avar Khaganate in the early 9th century. It flourished during the reign of Svatopluk I in the second half of the century, but collapsed in the first decade of the 10th century. "Great Moravia" was regarded as an archetype of Czechoslovakia, the common state of the Czechs and Slovaks, in the 20th century, and its legacy is mentioned in the preamble to the Constitution of Slovakia.
The title of Duke of Olomouc or Prince of Olomouc was held by members of the Bohemian Přemyslid dynasty in the Middle Ages in Moravia. Olomouc was a gord in Moravia.
