This paper represents the entire history of Mossad or at least the most important events that shaped its history. Work begins with an overview of the most important events in the history of contemporary Israel, ranging from the beginning of the first Aliyah at the end of the 19th century to the Protective Edge operation in 2014. The next chapters describe the organization of Mossad, the process of recruiting new agents and a chapter about other intelligence agencies in Israel such as Aman and Shabak. Cooperating with those was in some cases vital to the success of the operation. Next is a brief overview of the history of the Mossad seen through their directors, starting with Reuven Shilolah, the first director in 1949, to the current Yosef Meir Cohen, who took over the position in 2016. The next two chapters give an insight into the life and performance of a Mossad agent through the eyes of the most famous male and female agents. We continue with the chapter on the Nazi Hunt regarding fugitives as Eichmann, Cukurs and Mengele. The Hunt of Eichmann shows in detail the way Mossad operates when it comes to the task of kidnapping an individual. The next chapter shows the most important operations in the second half of the 20th century, operations such as the hijack of the MiG-21 aircraft in the 1960s, the acquisition of the secret speech of Nikita Khrushchev, various murders of Palestinian terrorist, the suppression of Saddam's attempt to obtain nuclear weapons and the killing of scientists like Gerald Bull. In the last chapter, we can see an example of co-operation with the United States, in this case the stopping of Al-Assad’s attempt to build nuclear weaponry at the beginning of the 21st century. Also there is a detailed example of how Mossad operates when it comes to the task of killing one of the Hamas leaders and weapon smugglers.
