It has become a proven fact that community participation is an obligatory aspect in the process of heritage conservation because in many cases, the fact that locals are not voice results in the lack of sustainability and cultural interest in the project. As discussed in this paper, the researcher explores how community involvement is linked to the development of conservation programmed in the old quarters of Sulaymaniyah, in the Kurdistan region, Iraq. Based on nine studies including both local and international settings the study determines eight major variables that describe participatory conservation including awareness, consultation, power-sharing, capacity building, financial participation, institutionalization, and cultural value recognition and feedback mechanisms. This paper will concentrate on the preservation of the city of Sulaymaniyah and it’s Great Mosque with the primary emphasis on its values and success within the industry. The results indicate that meaningful participation positively influences conservation through increasing authenticity, mobilizing resources, and making cultural relevance, whereas tokenistic strategies undermine the results. The research touches on the issue that the conservation of Sulaymaniyah is top-down and expert-based, which supposes that the systematic approach to community integration is going to produce more sustainable outcomes. The significance of the given study is in the fact that global participatory theories are adjusted to the local situation providing policy recommendations and a framework that can be applied in Iraq and throughout the region. The conclusion reiterates the fact that heritage sustainability lies in participatory conservation. Some of the suggested measures are neighborhood heritage committees, micro-grant support, adaptive reuse models, awareness programs and toolkits on professional participation to create a balance between modernization and protecting both tangible and intangible heritage.
