“Having founded Concepción, the Conqueror set out to expand the Spanish empire, establishing cities in the south of the country that were the centre of military garrisons, the seat of managers and headquarters of parishes, as well as the centre of doctrines and rural parishes, from which spread the evangelisation of the natives and the Christian civilisation..." (Fernando Campos Harriet) In the difficult and most desperate moments of siege by the indigenous people, the Spanish took refuge in their deep religious feeling, as if waiting for the miracle that fostered negotiations so that they would be able to continue expanding the empire of the conquerors under the Cross and the sword. Under the image of the Holy Crucifix they would manage, with the procession of Rere, to avoid the attack of the fierce Mapuche.
