Abstract
As a searcher in international relations, Ann Tickner was firstly stroke by the law number of women working in the field. She then realised that not only were women excluded as researchers, but also as subjects of study. That was the first step of her carrier as one of the main feminist authors in international relations theory. The work of Ann Tickner relies on classical visions of security and on their challengers, to introduce a brand new vision of International relations based on the concept of gender. Her main query was to know how the International Relations field would look in we introduced women in the field. International relations studies were born with realism, in the aftermath of the Second World War. For realist thinkers, security is defined in terms of national security. National security comes from power, in an anarchical world where no structure exists to regulate the relations between countries. Ann Tickner defines realism as concentrated on the "security of the State, which has to be achieved by increasing military capacities." The boundary between the state order and the international anarchy is tight, due to the lack of a central authority, which would "curve power's aggressive ambitions" .
