This article aims to highlight the importance of determining the temporal scope of the transition from armed conflict to peace. It will also consider the emergence of a new legal paradigm, jus post bellum, applicable to the post-conflict period, and the associated need for an appropriate regulatory framework. Given the unavoidable impact of armed conflict, the post-conflict period deserves particular attention, especially with regard to the need for a legal framework to facilitate the sustainable reconstruction of communities torn apart by conflict and ensure a lasting peace. After any kind of armed conflict, a solid legal framework is essential to finalize the end of hostilities, begin a sustainable peace process, build a united society and address the rifts caused by armed violence.
