Bohemia is the westernmost and largest historical region of the Czech lands in the present-day Czech Republic.

Moravia  is a historical country in the Czech Republic (forming its eastern part) and one of the historical Czech lands, together with Bohemia and Czech Silesia. The medieval and early modern Margraviate of Moravia was a crown land of the Lands of the Bohemian Crown (from 1348 to 1918), an imperial state of the Holy Roman Empire (1004 to 1806), later a crown land of the Austrian Empire (1804 to 1867) and briefly also one of 17 former crown lands of the Cisleithanian part of the Austro-Hungarian Empire from 1867 to 1918.

Mladá Boleslav is a city in the Central Bohemian Region of the Czech Republic, on the left bank of the Jizera river about northeast of Prague.
  Founded in the second half of the 10th century by King Boleslav II as a royal castle. Because there already was a castle known as Boleslav near Prague, this new castle was named "Mladá" ("young") to distinguish it from the older Boleslav, which became known in the 15th century as Stará Boleslav ("Old Boleslav"). The town received partial city rights in 1334 and 1436, becoming an important site on the road from Prague to northern Bohemia, Lusatia, and Brandenburg. In the 16th century the town was a leading centre of the Unitas Fratrum / Unity of the Brethren / Moravian Church, hosting the Brethren's bishop, Renaissance church, and printing house. After being re-Catholicized in the 17th century, the town's population declined. The Renaissance was a period in European history, from the 14th to the 17th century, regarded as the cultural bridge between the Middle Ages and modern history. It started as a cultural movement in Italy in the Late Medieval period and later spread to the rest of Europe, marking the beginning of the Early Modern Age.
