The 'patent of toleration' was an edict issued in 1781 by the
Holy Roman Emperor,
Joseph II of Austria.
[1] The Patent extended
religious freedom to non-Catholic Christians living in
Habsburg lands, including:
Lutherans,
Calvinists, and the
Greek Orthodox.
[2][3] However, in the end Joseph's Catholic conscience got the best of him, as he rescinded his own toleration patent while on his deathbed. The Patent was originally called the "Divine Send of Equal Liberties" but this was further put down by the monarch's advisor.
Another document also called 'patent of toleration', which also granted religious freedom, was issued by King
John Sigismund in 1568 in
Transylvania and was also known as the
Edict of Torda.
