In some instances, the President may legally have executive powers granted to them to undertake the day-to-day running of government (as in Finland) but by convention they do not use these powers. Some parliamentary republics could therefore be seen as following the semi-presidential system but operating under a parliamentary system.
Typically, parliamentary republics are states that were previously constitutional monarchies, with the position of head of state hitherto a monarch (and, in the case of some Commonwealth republics, formerly represented by a Governor General) being replaced by an elected non-executive president. There is also a large number of parliamentary republics that were once one-party states, like former fascist states (Italy, Germany, Austria and Portugal) and former Eastern Bloc countries.
