The era of violent extremism from diverse ideological groups has renewed the interest in radicalization. The rise of far-right political parties to power, the infiltration of right-wing populism to public institutions, persistent threat from religious radicalization exist together with anti-migrant and anti-gender discourses. The complex multidimensional nature of extremist tendencies force us to revisit conceptualization of radicalization in relation to political violence beyond securitization and specific grievances and acknowledge its transboundary nature. This panel begins with situating radicalization in a longer duration of political transformation building on the French case. It continues with looking at the relation between authoritarianization and mainstreaming of radicalization through the use of visual media in Turkey and Hungary. The analysis of the presence of far-right religious extremists in the Pride Parade in Israel carries the debate to another level, bridging the controversial relation between religion, nationalism and anti-gender discourse. Finally, we discuss how contemporary states manipulate citizen-making borders to deter radicalization and attempt to create trusted members.
