Bohemia is granted freedom of religion through the Letter of Majesty by the Holy Roman Emperor, Rudolf II.

Bohemia is the westernmost and largest historical region of the Czech Republic. Bohemia can also refer to a wider area consisting of the historical Lands of the Bohemian Crown ruled by the Bohemian kings, including Moravia and Czech Silesia, in which case the smaller region is referred to as Bohemia proper as a means of distinction.

Freedom of religion or religious liberty, also known as freedom of religion or belief (FoRB), is a principle that supports the freedom of an individual or community, in public or private, to manifest religion or belief in teaching, practice, worship, and observance. It also includes the right not to profess any religion or belief or "not to practice a religion".

The Letter of Majesty (1609) was a 17th-century European document, reluctantly signed by Rudolf II in his capacity as king of Bohemia, granting religious tolerance to both Protestant and Catholic citizens living in the estates of Bohemia. The letter also created a Bohemian Protestant State Church, run by said estates. A similar Letter was issued for Silesia, a part of the Lands of the Bohemian Crown.

Rudolf II was Holy Roman Emperor (1576–1612), King of Hungary and Croatia, King of Bohemia (1575–1608/1611) and Archduke of Austria (1576–1608). He was a member of the House of Habsburg.
