Excerpts from Books and Wikipedia
"The Golden Bull of 1222 was a golden bull, or edict, issued by King Andrew II of Hungary. King Andrew II was forced by his nobles to accept the Golden Bull (Aranybulla), which was one of the first examples of constitutional limits being placed on the powers of a European monarch. The Golden Bull was issued at the year 1222 diet of Fehérvár. The law established the rights of the Hungarian nobility, including the right to disobey the King when he acted contrary to law (jus resistendi). The nobles and the church were freed from all taxes and could not be forced to go to war outside of Hungary and were not obligated to finance it. This was also a historically important document because it set down the principles of equality for all of the nation's nobility." [Wikipedia] "But the Golden Bull did carve out a space where even a peasant could safely stand. “No man shall be either accused or arrested, sentenced or punished for a crime,” the second statute read, “unless he receive a legal summons, and until a judicial inquiry into his case shall have taken place.” And, like the Magna Carta, the Golden Bull made very clear that the instrument itself was greater than the king."
