Czechia, Slovakia, Poland, and Hungary represent countries where the position of the president and his relationship with the government are not the same and, moreover, evolve over time. The constitutional position of the head of state is not insignificant anywhere, but social and political expectations of what he will (not) do, as well as the degree of activity in the exercise of competencies and roles, differ. This can spill over into the realm of foreign and security policy. The chapter presents the constitutional competencies of the heads of state of the countries under study for foreign and security policy. It also notes how academics and the courts interpret constitutional texts. Given this, some importance can be given to the role of heads of state, but always less than that of the government, which directs foreign policy.
