Mieszko II Lambert
Mieszko II Lambert (c. 990 – 10/11 May 1034) was King of Poland from 1025–1031, and Duke from 1032 until his death.
He was the second son of Bolesław
I the Brave but the eldest born from his third wife Emnilda of Lusatia.
He was probably named after his paternal grandfather, Mieszko I.
His second name, Lambert, sometimes erroneously considered to be a nickname, was given to him as a reference to Saint Lambert.
Also, it is probable that this name Lambert was chosen after Bolesław's half-brother Lambert.
It is thought that the choice of this name for his son was an expression of warming relations between Bolesław I and his stepmother Oda.
He organized two devastating invasions to Saxony in 1028 and 1030.
Then Mieszko II ran a defensive war against Germany, Bohemia and the Kievan princes.
Mieszko II was forced to escape from the country in 1031 after an attack of Yaroslav I the Wise, who installed Mieszko's older half-brother Bezprym onto the Polish throne.
Mieszko took refuge in Bohemia, where he was imprisoned by the Duke Oldrich.
In 1032 he regained power in one of the three districts, then united the country, making good use of the remaining power structures.
At this time, several Polish territorial acquisitions of his father were lost: Upper Lusatia (also known as "Milsko"), part of Lower Lusatia, Red Ruthenia, western and central part of Upper Hungary (now Slovakia) and probably Moravia.
Mieszko II was very well educated for the period.
He was able to read and write, and knew both Greek and Latin.
He is unjustly known as Mieszko II "Gnuśny" (the "Lazy,Stagnant" or "Slothful").
He received that epithet due to the unfortunate way his reign ended; but at the beginning he acted as a skillful and talented ruler.

Aron (bishop of Kraków)
Aron was an 11th- century Polish Bishop of Krakow, then Archbishop and the first Abbot of the Benedictine house in Tyniec.
His name is known from the 13th century chronicle “" Sede Vacante with krakowski" ” which lists the names of the first nine Bishops but which does not provide years.
He arrived in Poland probably from Cologne, where the Archbishop was Hermann, uncle of Casimir the Restorer, or from Leodium.
He was at first the abbot of the Benedictine monastery in Tyniec but in 1046 he was made Bishop of Krakow.
He was Bishop in Kraków from 1046 to 1059.
Because of the collapse of the Gniezno Bishopric during the dynastic struggles for the Polish Throne and the Czech invasion by Duke Bretislaus Piast in 1039, the Pope raised the see of Kraków to be an archbishopric around 1049.
Prince Casimir the Restorer considered moving the capital of the Polish church to Kraków during his reconstruction of the church.
Some researchers speculate, however, that Aron received the Pallium as a personal badge of honour rather than a restructuring of the church.
He was a strong supporter of Duke Casimir the Restorer, and an organizer of the Church in Kraków and a supporter of the Clunic movement.
He is also credited with founding the library at Kraków.
The chapter of Kraków has adopted for his personal coat of arms.
He died in 1059, either on 15 May or on 9 October.
Bishop Aron is a character in the historical novel, Silver Eagles by Theodora Parnickiego.
Casimir I the Restorer
Casimir I the Restorer (b. Kraków, 25 July 1016 – d. Poznań, 28 November 1058), was Duke of Poland of the Piast dynasty and the "de jure" monarch of the entire country from 1034 until his death.
He was the only son of Mieszko II Lambert by his wife Richeza, daughter of Count Palatine Ezzo of Lotharingia (of the Ezzonids) and granddaughter of Emperor Otto II.
Casimir is known as "the Restorer" because he managed to reunite all parts of the Polish Kingdom after a period of turmoil.
He reinstated Masovia, Silesia and Pomerania into his realm.
However, he failed to crown himself King of Poland, mainly because of internal and external threats to his rule.
