Document 8: Prussian education system: The Prussian education system refers to the system of education established in Prussia as a result of educational reforms in the late 18th and early 19th century, which has had widespread influence since. It is predominantly used as an American political slogan in educational reform debates, since it was adopted by all American K–12 public schools and major universities as early as the late 18th century, and is often used as a derogatory term for education in the service of nation-building, teaching children and young adults blind obedience to authority, and reinforcing class and race prejudice. The actual Prussian education system was introduced as a basic concept in the late 18th century and was significantly enhanced after Prussia's defeat in the early stages of the Napoleonic Wars. The Prussian educational reforms inspired other countries and remains important as a biopower in the Foucaultian sense for nation-building. Compulsory education on the Prussian example was soon mirrored in Scandinavia, and United States started to adopt the Prussian example. Early American adopters include Daniel Coit Gilman, who set up The General Education Board, later renamed The Rockefeller Foundation, and first president of Johns Hopkins, John Dewey at the University of Chicago, James McKeen Cattell at The University of Pennsylvania and Columbia University, Henry Philip Tappan at The University of Michigan, James Earl Russell at the New York College for the Training of Teachers, and many more.

Document 12: Union of Horodło: The Union of Horodło or Pact of Horodło was a set of three acts signed in the town of Horodło on 2 October 1413.

The second and third acts were composed by the Polish nobility (szlachta) and Lithuanian boyars respectively. The union amended the earlier Polish–Lithuanian unions of Krewo and Vilnius–Radom. Politically, Lithuania received more autonomy as, after the death of Vytautas, the Lithuanian nobles could choose another Grand Duke instead of passing the title to Władysław II Jagiełło or his heir. However, culturally, Lithuania and Poland grew closer. Lithuania adopted Polish institutions of castellans and voivodes. Catholic Lithuanian nobles and church officials were granted equal rights with the Polish nobles and clergy. Forty-seven selected Lithuanian nobles were adopted by Polish families and granted Polish coats of arm. Thus the union signified the beginnings of Polonization of Lithuanian culture and the rise of the Lithuanian nobility. It was one of the major steps towards the modernization and Europeanization of Lithuania.
Document 13: Warsaw Confederation: The Warsaw Confederation, signed on January 28, 1573 by the Polish national assembly ("sejm konwokacyjny") in Warsaw, was the first European act granting religious freedoms.

While it did not prevent all conflict based on religion, it did make the Commonwealth a much safer and more tolerant place than most of contemporaneous Europe, especially during the subsequent Thirty Years' War.
