 The collective presidency was completely abolished in favor of the post of President of the Republic of Croatia with the adoption of a new constitution on 22 December 1990.The Croatian Parliament then declared independence on 25 June 1991, when Tuđman formally became the first president of an independent Croatian nation under the name the "Republic of Croatia".Thus, the current office is not considered a continuation of the line of heads of state who held office while Croatia was a constituent republic in Yugoslavia, called SR Croatia (until 25 July 1990) and the Republic of Croatia (25 July-22 December 1990), and whose heads of state held a sub-national office.
