This chapter delves into the Jordanian regime’s policies towards the Muslim Brotherhood by dividing the history of the organisation in Jordan into three different periods: 1946–1989, during which relations with the regime were mostly good and characterised by cooperation; 1989–1999, when the regime and the Brotherhood had less need for each other and the latter began to contest the former’s power; and 1999–2016, during which both parties took a more confrontational approach, with the regime eventually subjugating the Brotherhood to its will. Because the next three chapters are dedicated to the Muslim Brotherhood’s ideological moderation or radicalisation in the context of Jordanian politics and society, this chapter will focus on the group’s behaviour and the regime’s inclusion or repression of the organisation.
