At the time of his presidential candidacy, he held the position of senior lecturer in history at the University of Iceland. His primary field of research is modern Icelandic history, a subject on which he has published numerous influential works.
His publications cover a wide range of critical topics in Icelandic history, including the Cod Wars, the profound 2008-2011 Icelandic financial crisis, and an in-depth analysis of the Icelandic presidency.

3. Presidential candidacy
Guðni Thorlacius Jóhannesson's entry into politics was a direct response to public sentiment and a desire to contribute to national stability following a period of political turmoil.
3.1. Decision to run and campaign
Guðni announced his decision to run for president on 5 May 2016. His public profile had significantly risen prior to his candidacy due to frequent appearances on live television. In these appearances, he provided expert commentary and historical context in the wake of the Panama Papers scandal, which led to the ouster of then-Prime Minister Sigmundur Davíð Gunnlaugsson. As a scholar of the Icelandic presidency, Guðni was uniquely positioned to discuss the constitutional options available to the incumbent president, Ólafur Ragnar Grímsson, and other political actors during this period of crisis. His clear and insightful analyses resonated with the public, leading to widespread calls for him to seek the presidency himself.
His campaign platform emphasized constitutional reform, particularly supporting a citizen initiative referendum provision. Guðni positioned himself as an independent candidate, unaffiliated with any of Iceland's political parties. He publicly stated his intention to be a "less political president" than his predecessor, highlighting his non-partisanship as a key differentiator. Throughout his campaign, Guðni consistently stressed the paramount importance of unity for the small nation of Iceland.
3.2. Election results
Early polls indicated significant public support for Guðni. His popularity surged further following incumbent President Ólafur Ragnar Grímsson's decision to withdraw from the race.

On 25 June 2016, Guðni was elected President of Iceland, securing a plurality of 39.1% of the vote, totaling 71,356 votes. His victory marked a significant moment in Icelandic politics, signaling the public's desire for a non-partisan leader focused on national cohesion.
4. Presidency of Iceland
Guðni Thorlacius Jóhannesson's presidency was characterized by a commitment to national unity, a non-political approach, and exceptionally high public approval, reflecting a strong connection with the Icelandic people.
4.1. Term and major activities
Guðni officially assumed office as the sixth President of Iceland on 1 August 2016. At 48 years old, he became the youngest president in Iceland's history. Early in his term, Guðni faced the critical task of overseeing negotiations for the formation of a new government following the 2016 Icelandic parliamentary election on 29 October. These negotiations proved challenging, as no pre-election coalition had secured a majority, and potential majority coalitions comprised parties with widely divergent policy positions. Despite the complexities, Guðni navigated this period with a steady hand, facilitating the democratic process.
His presidency was marked by a consistent focus on unity and a less partisan approach, fulfilling his campaign promise. He maintained a high level of public engagement, both domestically and internationally. In the 2020 Icelandic presidential election, Guðni was overwhelmingly re-elected with 92.2% of the vote, marking the second-largest electoral victory in Icelandic presidential history. On 1 January 2024, in his New Year's address to the Icelandic people, Guðni announced that he would not seek re-election in the 2024 Icelandic presidential election, concluding his two terms in office on 1 August 2024.
4.2. Events during presidency and public reception
Throughout his presidency, Guðni maintained exceptionally high approval ratings, unprecedented for an Icelandic politician. Just one month into his term, an MMR survey reported his approval rating at 68.6%, the highest measured for an Icelandic president by that pollster since its establishment in 2011. By December 2016, his approval rating soared to 97%, a figure virtually unseen in Icelandic politics. In April 2019, his approval rating remained remarkably high at 93.5% among those who expressed an opinion in a survey.

One notable incident that garnered international attention occurred in February 2017, when Guðni jokingly expressed his desire to ban pineapple as a pizza topping.
