PROBLEM: Passage: In April 1543 Suleiman launched another campaign in Hungary, bringing back Bran and other forts so that much of Hungary was under Ottoman control. As part of a Franco-Ottoman alliance , French troops were supplied to the Ottomans in Hungary: a French artillery unit was dispatched in 1543-1544 and attached to the Ottoman Army. In August 1543, the Ottoman succeeded in the Siege of Esztergom The siege would be followed by the capture of the Hungarian coronation city of Székesfehérvár in September 1543. Other cities that were captured during this campaign are Siklós and Szeged in order to better protect Buda. However, continuous delay of the push toward the west, because of the siege of these fortresses, meant that the Ottomans could not launch any new offensive against Austria. From 1548 to the end of the war, a Habsburg Spanish infantry tercio which had fought in the Schmalkaldic War, led by Maestre de campo Bernardo de Aldana, was detached in Hungary to fight against John Zápolya's supporters on behalf of Ferdinand. In fact, the Holy Roman Emperor Charles V sent Spanish troops to help his brother regularly from 1527 to 1553, a support that proved instrumental in Hungary remaining inside Christianity.
Question: What was former year that Charles V sent Spanish troops to help his brother?

SOLUTION: date

PROBLEM: Passage: Upon his appointment as Bishop of Wrocław in 1198, Jarosław of Opole, elder son of the Silesian duke Bolesław I the Tall, received the territories around the town of Nysa  from his father. After Jarosław's death in 1201, his half-brother Duke Henry I the Bearded of Silesia decided to leave Nysa, as well as the castellany of Otmuchów, under the control of the Diocese of Wrocław, while the rest of the late Jarosław's Upper Silesian lands were annexed by his uncle Mieszko IV Tanglefoot in the following year. In 1290 Henry IV Probus, duke of Lower Silesia at Wrocław, gave the bishops privileges of autonomy on their lands in Nysa, creating the legal basis for the Duchy of Nysa. Henry of Wierzbna, Bishop of Wrocław from 1302 to 1319, was the first to actually use the title of a Duke of Nysa. The duchy in its original form only lasted until 1335, when Silesia passed to the Kingdom of Bohemia by the Treaty of Trentschin. In 1342 Bishop Przecław of Pogorzeli swore the oath of fealty to King John the Blind and afterwards played a vital role in the negotiations for the 1348 Treaty of Namslau between John's successor Charles IV and King Casimir III the Great of Poland. Pogorzeli also significantly enlarged his territory by acquisition of Grodków  from Duke Bolesław III the Generous of Brzeg in 1344. For the next two hundred years, the Polish, Czech and German inhabitants of Nysa-Grodków lived in relative harmony, even during the beginnings of the Reformation as the control of the region switched between Protestant and Catholic rulers. This ended with the Thirty Years' War.
Question: How many years was Henry of Wierzbna the Bishop of Wroclaw?
