 When the Presidium was abolished in the constitutional reforms of 1953, the position defaulted to the Presidents of the Parliament.In 1974, a new constitution brought about the collective Croatian Presidency, with the President of the Presidency as head of state of the Republic.The next constitution of 1990 abolished the Presidency and established a single office of the President, which (under a new semi-presidential system) was now much more empowered than any of the previous offices.
