In this study, participation in murder and wounding crimes was examined in the context of Ottoman law. In this manner, the point of view of Islamic law, which guides Ottoman law, was included, and Hanafi views were emphasized specific to Ottoman. It has been determined that Hanafi lawyers have opinions that are different from others in the context of participating in crimes of killing and wounding. The necessity of obliging the perpetrator to consider secondary partner as the main partner in case of decriminalization, if they are persevering, is one of the opinions peculiar to Hanafis. It has been observed that the fatwas issued and the laws issued in Ottoman law have a parallel attitude to Hanafi views. It can be said that the issue is being considered in more and more detail within the framework of the increasing legalization activities during the Tanzimat period. In the study, the cases of joint killing and wounding in Ottoman practice were also examined, and it was seen that the parties were in favor of peace and renunciation in cases of direct participation. When indirect participation cases were raised, the punishment of the secondary partner was usually lighter compared to the main partner.
