Historical calendar: September 10, 1526 – Mazovia corp to Poland

Anniversary of the accession of Mazovia to the Crown of the Kingdom of Poland.

Today, in our calendar we will look at the inclusion of the old territory in Poland in Mazowsze.

As the individual Masovian Piast lines expired, further lands were connected to the Crown. In 1462 within the borders of Poland there was the country of Ravisko and Gostyninska, in 1476 the land of Sochaczewska, and in 1495 the dukedom of Płockie. In 1526 he died Janusz III, the last prince of the Mazovia branch of the Piast family. The Duchy was to be ruled by the Polish king, but the way it was incorporated and the conditions of belonging had not been clearly defined.

Two different concepts of joining Mazovia appeared. The first assumed that it would receive a separate prince who was to be the lord of Poland. Supporters of this solution were Mazovian dignitaries, who wanted to keep their privileged position and, above all, Queen Bona, who wanted the state to be given to her son, Sigismund August, as the Jagillons' domain in the Republic.

In turn, the Polish rulers felt that Mazobosz should be straight incorporated into the Crown. The union with Poland was besides supported by the tiny and average Mazowiecka nobility. King Sigismund Old advocated the option of a complete incorporation of the district.

The problem of Mazovia was not an interior substance of the Kingdom of Poland. 2 European families, Hohenzollerns and Habsburgs, expressed interest in the province. The Prussian ruler Albrecht Hohenzollern planned to get Mazovia thanks to the matrimony of his brother to Princess Anna, sister of Janusz II.

The Habsburgs, in turn, wanted to receive the erstwhile hub territory in exchange for the failure of flax power over the Duke of Bari, the hereditary power of Queen Bona. The threat of internationalisation of the case and of creating a conflict between the dynasties has accelerated the action of the King of Poland to solve the problem.

On September 10, 1526, Zygmunt Stary officially took his oath from the Mazovian states, gathered at the parliament in Warsaw. He managed to convince opponents of joining the province, fulfilling any of their demands. Princess Anna received territorial assignments, and Mazobosz was given the post of Vice-Sgerent (Register) not existing in another Kingdom provinces.

The final incorporation was only announced 3 years later, at a parliament in Piotrków, whose members included MPs and Mazowieckie Senators for the first time. Gradually, Mazovia was unified with the remainder of the country in terms of political and administrative terms. The nobles of the state received the same privileges as the crown; earthly seymites were besides formed in the territory of Mazovia.

A separate mazowieckie seym functioned until 1540, later becoming a provincial general seymik. Mazowsze was divided into 3 provinces: Rawskie, Płockie and Mazowsze, reflecting the division into regions from the times of the princes of the city. It was only in 1577 that the Polish law was adopted in the district, but it kept any differences, the alleged Masovian excepts.
