Henry III the White (; â 3 December 1266), a member of the Silesian Piasts, was Duke of Silesia at Wrocà Âaw from 1248 until his death, as co-ruler with his brother Wà Âadysà Âaw.
He was the third son of the Polish high duke Henry II the Pious, by his wife Princess Anna, daughter of the Pà Âemyslid king Ottokar I of Bohemia. After the heroic death of his father at the Battle of Legnica on 9 April 1241, Henry III was still a minor and found himself under the care of the mother together with his youngest brothers Konrad and Wà Âadysà Âaw.
In 1242, the unexpected death of his brother Mieszko, placed him in the second place immediately after his oldest brother Bolesà Âaw II the Bald. Since then, he became in the head of the political opposition in the Lower Silesia against the government of Bolesà Âaw II.
The first appearance of Henry III as adult was found only in 1247; however, Bolesà Âaw II didn't have any intentions to share the power with him. He only changed his mind after the revolt of his brothers, who even captured him. Henry III was made the co-ruler with his older brother. The cooperation between the brothers was not very good and a year later, under pressure from Henry III, they decided to make a division of the districts Legnica–Gà Âogów–Lubusz and Wrocà Âaw. Bolesà Âaw, as the older brother, had the opportunity to choose his district; he decided on Legnica, because gold had been discovered in the Kaczawa and Wierzbiak Rivers.
Bolesà Âaw II may have hoped that Henry III encountered serious difficulties with Wrocà Âaw (which he received in the division), so at the end the Duchy would come back to him. These expectations, however, never happened. Henry III was a strong ruler, and almost immediately he could impose his will over the powerful nobility. An additional point of the agreement was the obligation to offer hospitality to the younger brothers, Konrad and Wà Âadysà Âaw, who were destined to the espiritual career. Henry III's successful attempts to make Wà Âadysà Âaw entered in the Church had a total contrast with the relations between Bolesà Âaw and Konrad. Between them, were several disputes, in particular after Konrad claimed his own district and refused to become a priest. Open war between Henry III (who supported Konrad) and Bolesà Âaw II was only a matter of time.
Bolesà Âaw II, without funds, began to fear the prospect of an armed conflict with his brothers. In order to obtain the necessary resources to conduct the war, he decided to sell half of Lubusz to the Archbishop of Magdeburg. Unfortunately for him, Henry III also began to seek an ally in the rulers of Meissen. Defeated, Bolesà Âaw II was forced to give the district of Gà Âogów to Konrad, who wished to enforce Henry III's intervention over Legnica in 1250. When Konrad decided on Bolesà Âaw II's kidnapping, even to the ruler of Wrocà Âaw, this was too much. All these treatments are not expected to take effect over the Duke of Wrocà Âaw, however, as Henry III in his relations with the brothers now sought to avoid open conflicts. Only in 1253, when the authority of Bolesà Âaw II collapsed completely, Henry III helped him to return to his Duchy.
Between the 1250s and 1260s Henry III became the most powerful Piast Duke of Lower Silesia. Consequently, it was not surprising that he was active in international politics. Henry III made alliances with his relatives, the Dukes of Opole and Gà Âogów, and with the Kings of Bohemia, Wenceslaus I and Ottokar II (in the years 1251, 1252, 1259, 1261 Henry III was in the royal court in Prague). The cooperation with the Pà Âemyslids, however, was not having the expected results. After Bohemia decided to interfere in the War of the Babenberg Succession over Austria with the support of the English, Henry III decided to reaffirm his alliance with them and repudiated his treaty with the rulers of Greater Poland, Przemysà  I and Bolesà Âaw the Pious and the ÃÂrpád dynasty. They decided to punish Henry III, and during 1253âÂÂ1254 the Duchy of Wrocà Âaw was besieged and plundered. Attempts to force concessions, either by blackmail (as was the case in 1256, when the sons of Henry II the Pious took the intervention of the papal Curia, but to regain some lost by Bolesà Âaw the Pious) or bribery (the exchange of Daà Âkow in 1262, promised by Henry III to Bolesà Âaw the Pious and Bolesà Âaw V the Chaste if they switched to the Bohemian side) did not yield a positive result.
In the internal politics, Henry III stood on guard to defend the prerogatives of the Piast dynasty, and the church actively supported him, because Henry III supported Bishop Thomas of Wrocà Âaw against Bolesà Âaw II in their disputes. This particular policy was not pleasing the Wrocà Âaw nobility; by 1266 several riots erupted among the nobles and knights, which contributed to the premature death of the Duke.
Another manifestation of Henry III's rule was the intensive German colonization of Lower Silesia, which significantly contributed to the growth and prosperity of his Duchy. Many cities were founded during this time, and in Ostrów Tumski in Wrocà Âaw a huge castle was built. Henry III also generously supported artists in his court. In the 13th century, German was the language of policy.
The dictatorial internal politics of Henry III led to a rebellion of the townspeople. The pretext emerged in the mid-year 1266 when they tried to forced a division of the Duchy of Wrocà Âaw between Henry III and his brother Archbishop Wà Âadysà Âaw of Salzburg. Wà Âadysà Âaw was not the head of the revolt and this was total surprise to him. His origins are certainly among the nobility.
The Polish historian Jerzy Mularczyk, had two possibles leaders of the revolt: first, the Bishop Thomas of Wrocà Âaw, who, taking advantage from Henry III's apparent weakness, tried to strengthen the position of the church; but after watching how the Duke concentrated all the power in his hands and stripped the nobility from his privileges, he feared that this also happened with the Church hierarchy, which certainly he did not permit.
The second possible leader was to be Bolesà Âaw II the Bald who hoped, in case of the eventual division of the Duchy of Wrocà Âaw and the expected death of Wà Âadysà Âaw without heirs -because he followed the spiritual career-, recovered at least 1/3 of Wrocà Âaw (the remaining 2/3 would be retained by Henry III, his other brother Konrad, and their descendants) for him or his successors. The rapprochement between Bishop Thomas and Bolesà Âaw II was proved by a document, in which the Duke of Legnica called Bishop Thomas as his "compater noster", an unusual way to refer to somebody who supposed a close bond between them. However, there did not exist direct evidence for this theory. Of the revolt of the mid-year 1266 little is known, but it certainly failed, as the Duchy was not divided.
Henry III was not in time to celebrate his success, because only a few months later he suddenly died when he was only thirty-nine years old. Like is common in such situations, soon began the rumours about poisoning. This is reflected, in the Kronika polska written by the cisternian monk Engelbert around 1283âÂÂ1285.
The source of the unnatural circumstances of his death suggests that some of the Silesian Dukes maybe conspired against him, and this suggestion is not unfounded. This was proved by the last months of Henry III's life, as he spent all this time fighting against the internal opposition of his rule. Certainly there was a large group of people affected by the Duke's punishment after the end of the revolt who decided to eliminate him from the scene.
The participation of the two possible leaders of the revolt of mid-1266, Bishop Thomas and Bolesà Âaw II the Bald, and seems unlikely. Their benefits from Henry III's death were small: Wrocà Âaw passed into the hands of Henry IV, a minor, under the regency of the Archbishop Wà Âadysà Âaw, which doesn't change the radical politics of his late brother. Henry III's dying request to extend the rule of Wà Âadysà Âaw's regency was made with the clear purpose to reduce the suspicion of guilt against him. Guilty for his death should therefore be found primarily among those dissatisfied with the rule of knights, or divide Wrocà Âaw.
In addition to the Kronika polska, the mysterious death of Henry III was written even on his tombstone: Anno domini Millesimo, Nonas Decembris obiit veneno inclitus dux Wratislaviensis Henricus tertius, secundus filius secundi Henrici, a Thartaris. From there, this information will be received by the Chronicle of the Silesian Dukes and the Genealogy and life of St. Hedwig to Jan DÃ Âugosz.
The year of Henry III's death is absolutely certain, as is confirmed by all the documentary and oral sources of that time. However, there are disparities about the exact date. 3 December was confirmed as the best, although there are also sources date: 1 December, 5 December and 29 November. Henry III was buried in the Clare Church in Wrocà Âaw, which was still under construction.
On 2 June 1252, Henry III married firstly with Judith (b. 1222/25 â d. 4 December 1257/65?), daughter of Duke Konrad I of Masovia and widow of Mieszko II the Fat, Duke of Opole. They had two children:
Shortly before his death in 1266, Henry III married secondly with Helena (b. 1247 â d. 12 June 1309), daughter of Albert I, Duke of Saxony. They had no children.
