The preambles are used in the Czech legal system during the last twenty years rather rarely. Nonetheless, constitutions in the Czechoslovak history as in the Czech history are traditionally introduced by the preambles. As the Czech constitutional system inclines to consist of more constitutional legal acts at the supreme level of the interior legal system, we can found two constitutional preambles in the recent Czech constitutional system. Both top constitutional acts-the Constitution and the Charter of Fundamental Rights and Basic Freedoms are preceded by their own preamble. The preambles differ as they are focused on different part of constitutional issues. Despite of this obvious fact they are built-up on some features, which are common to both of them. The preambles are characterized by a modest form-their purpose is to explain, why the new chapter of the legal development is opened, and to offer us a common starting line. Nonetheless, they also keep to us a freedom of movement in the new legal period. Their main goal is to connect the people, not to divide, if the constitutional act, which is introduced by them, should be an expression of the common national will.
