Implementation agreements specify the details of a comprehensive agreement or framework agreement. An implementation agreement almost always requires a new round of negotiations with the parties involved. These negotiations refine and define framework agreements or comprehensive agreements in practice. The aim of the implementation agreements is to develop the modalities and mechanics in order to facilitate the implementation of the comprehensive agreement. The terms of application are not always written formal documents. Sometimes these are oral commitments, exchanges of letters and joint public statements that help accelerate implementation. Because of this fact, it is generally very difficult to keep implementation agreements in mind. Often, the informality of these agreements complicates the engagement of the parties. While formal written implementation agreements often take longer, it is generally considered that the parties are required, serious and obligated to implement them. Peace agreements are treaties that aim to end a violent conflict or significantly modify a conflict so that it can be dealt with in a more constructive manner. There are different types of agreements that can be reached during a peace process. Each type of agreement has its own purpose and serves in itself to give a positive impetus to a final settlement.
However, these agreements are not easy to distinguish, as content can sometimes overlap. Not all types of agreements are necessary for each conflict. Some processes can lead to progressive agreements leading to a comprehensive settlement. Other peace processes could try to negotiate an agreement in a comprehensive way. The earliest recorded peace treaty, although rarely mentioned or memorable, was between the Hehitennic Empire and the Hayasa-Azzi Confederacy, circa 1350 BC. More famously, one of the first recorded peace agreements between the hemetic and Egyptian empires was concluded after the Battle of Kadesh in 1274 BC (see Egyptian-Russian Peace Treaty). The battle took place in Syria today, the whole Levant was then taking place between the two empires. After an extremely costly four-day battle, in which neither side gained a substantial advantage, both sides claimed victory.
The lack of solution led to further conflicts between Egypt and the Hethians, Ramesses II conquering the city of Kadesh and Amurru in its eighth year of rule.  The prospect of another long-running conflict between the two states finally convinced their two leaders, Hatusili-III. Ramesses to end their dispute and sign a peace treaty.
