 Historian of the church Goñi Gaztanbide ("Historia de los Obispos de Pamplona", 1985) is adamant in his criticism, denouncing the "Castilian assimilation of Navarrese Church at all levels," to the point of considering that it was subjected to a colonial regime.The Navarrese continued turning their eyes to their Protestant brethren to the north, in Henry II's independent Navarre with Béarn.Navarre, like Gipuzkoa, became a hotspot of penetration for Protestant ideas as early as 1521, when the Inquisition seized and set fire to a number of books.
