Clan Ostoja
At the end of 15th and beginning of the 16th century the Commonwealth was the biggest and one of the most powerful countries in Europe. In 1569, the Union of Lublin created a real union of the Polish-Lithuanian Commonwealth, replacing the personal union of the Kingdom of Poland and the Grand Duchy of Lithuania. It encompassed territories from Poland, Lithuania, Prussia, Latvia, Belarus, Ukraine, Moldavia, Podolia, part of Spisz and part of Russia including Smolensk.
The Union of Lublin marked the end of a 150 years period of Commonwealth expansion and consolidation. The skills needed to expand and secure national borders were different from what was required when the expansion was completed. The new nation needed new kind of administration, and as new goals become paramount the age of brave knights passed. Clan organization lost importance, and interfamilial cooperation lessened.
Throughout the Commonwealth, the administrative structure was generally similar, albeit with some important differences. In Poland, the use of titles by the nobility was formally discontinued by the constitution of 1638, the nobility being equal according to the law, which was confirmed in 1641 and 1673.
However, in actual practice families with close descent from the major dynastic origins such as the Ostoja families of Stibor line or some to the Clan adopted families, who had held important positions in Poland during medieval times and thus held titles such as comes or dux (duke, voivode, count palatine) never accepted the equality system and they continued to utilize their titles, particularly when traveling abroad or on diplomatic missions.
