Following the end of the war, parliamentary elections were held in 1995, which resulted in a victory of the ruling Croatian Democratic Union. Zlatko Mateša became the new Prime Minister of Croatia, replacing Nikica Valentić, and formed the first peacetime government of independent Croatia. Elections for the Zagreb Assembly were held at the same time, which were won by the opposition. This led to the Zagreb crisis since the president refused to provide formal confirmation to the opposition parties proposed Mayor of Zagreb. In 1996 mass demonstrations were held in Zagreb in response to revoking broadcasting license to Radio 101, a radio station that was critical towards the ruling party.
