The Henrician Articles summarized the accumulated rights of Polish nobility, including religious freedom guarantees, and introduced further restrictions on the elective king; as if that were not enough, Henry also signed the so-called pacta conventa, through which he accepted additional specific obligations.
Articuli Henriciani on kokku võetud Poola aadli kogutud õigused, sealhulgas usuvabaduse garantii, ja kehtestatud täiendavad piirangud valitavale kuningale; nagu sellest veel vähe oleks, allkirjastas Henryk ka niinimetatud pacta conventa, mille kaudu ta nõustus täiendavate erikohustustega.
