The presence of the external factor is usually related to the context of the popular hirak, the periods of political transition and the transitional phases in many countries. This factor is evident in countries with a geopolitical position in regional and international competition. This study discusses the variable of the external factor in the 22 February 2019 hirak in Algeria by examining the limits of international and regional interventions in steering the course of the popular hirak compared to other Arab cases where the external factor seemed to be more influential. It aims to discuss the determinants of Algeria's relations with regional and international powers and to explain the issue of the lack of external interference in the popular hirak, ending with the modalities of the future of the turbulent political path and discussing the possibilities of transformation from abroad. The study concludes that the lack of regional and international intervention in the popular hirak is mainly related to geopolitical and strategic constraints, far from value and normative considerations. The behaviour of external forces is determined by Algeria's geopolitical situation. The risks of instability in the country would create highly complex security challenges in the Mediterranean region. Added to this is the importance of Algeria in assessing the strategic balances in the region, especially for European security.
