The concept “Racialization” is introduced as “the extension of racial meaning to a previously racially unclassified relationship, social practice or group.” From what I’ve learned through this weeks materials, I consider this process as the introduction of local racial understandings to foreign, in other words, incompatible or distinctive believes social groups. A brilliant example will be the one introduced in the lecture, the conflict between Catholics, Christians and Jews in Spain. Catholics and Christians believes that most crimes involves the participation of Jews. So this is considered as the emergence of religious conflicts between local residences in Spain. Some Christians appeal their complaint through their behaviors, such as lending money to Jews and receiving high usury. And by this time period, Catholics and Christian combined together against Jews. And as Ferdinand and Isabella started the control of the whole nation and the carry out of Alhambra Decree. Jews were forced to wear yellow badges in order to test if they were engaged in violence and protests. They also compel local Jews to change their belief, or otherwise they must move abroad. However, superiors still worried about the true believers of God and the existence of religious conflicts, so they released the “Blood Purity Law” to exam if the Jews were truly believed in God. It’s not hard to see that the racialization process throughout the instance, from the emergence of the religious conflict, relatively statements carried out against unclassified groups and the results after a sires of actions took placed. Similar processes can be found in the Casta paintings and the slavery in North Africa, America and Europe.
