defeat an incumbent president running for reelection, as well as the second woman in the world to do so, after Violeta Chamorro of Nicaragua in 1990. She is also the first candidate of any gender to defeat an incumbent Croatian president. In addition, Grabar-Kitarović is the only presidential candidate to date to have won a Croatian presidential election without having won the most votes in the first round of elections, as she lost it by 1.24% or 21,000 votes. Furthermore, the 1.114 million votes she received in the second round is the lowest number of votes for any winning candidate in a presidential election in Croatia and the 1.48% victory margin against Josipović is the smallest in any such election to date. Presidency (2015–2020) Less than nine months into Grabar-Kitarović's term the European migrant crisis began to escalate with large numbers of migrants entering Greece and Macedonia and crossing from Serbia into Hungary, with the latter beginning the construction of a fence on its southern border as a result. In September 2015, after Hungary constructed a fence and closed its border with Serbia, the flow of migrants was redirected towards Croatia, causing over 21,000 migrants to enter the country by 19 September, with the number rising to 39,000 immigrants, while 32,000 migrants exited Croatia, leaving through Slovenia and Hungary. She appointed Andrija Hebrang her commissioner for the refugee crisis. With the parliament expected to dissolve by 25 September, Grabar-Kitarović called parliamentary elections for 8 November 2015. They proved inconclusive and negotiations on forming a government lasted for 76 days. Grabar-Kitarović had previously announced on 22 December 2015, if there were no agreement on a possible Prime Minister-designate in the next 24 hours, she would call for an early election and name a non-partisan transitional government (which would have reportedly been headed by Damir Vanđelić), thereby putting intense pressure on the political parties involved in the negotiations regarding the formation of the new government, to find a solution. The crisis finally ended on 23 December 2015 when Grabar-Kitarović gave the 30-day mandate to form a government to the non-partisan Croatian-Canadian businessman Tihomir Orešković, who had been selected by HDZ and MOST only hours before the expiration of the President's delegated time frame for the naming of a Prime-Minister-designate. On 24 August 2015, Grabar-Kitarović was, as Armed Forces Commander-in-Chief, presented with a petition for the introduction of a Croatian fascist Ustaše movement
