This paper highlights the impact of conflicts in the Muslim World on violent Jihadi radicalisation in Europe. Though the radicalisation process in European diaspora Muslim communities has domestic causal factors, political conflicts in diaspora community's countries of origin, or in countries with Muslim majorities in general, are particularly relevant. These conflicts contribute to radicalisation processes in Europe through a number of trajectories. These trajectories, and the factors behind them, are examined, drawing upon empirical data in the TERAS-INDEX project and a number of examples with a particular reference to the experiences of Germany.
