Zlatko Lagumdžija (born 26 December 1955) is a Bosnian politician and diplomat serving as the Permanent Representative of Bosnia and Herzegovina to the United Nations since July 2023. He served as Chairman of the Council of Ministers of Bosnia and Herzegovina from 2001 to 2002. Having also served as Minister of Foreign Affairs from 2001 to 2002 and from 2012 to 2015, he was president of the Social Democratic Party (SDP BiH) from 1997 to 2014 as well.

Lagumdžija was born in Sarajevo in 1955. His father Salko was mayor of Sarajevo in the 1960s. Lagumdžija graduated from the University of Sarajevo in 1981. He did postdoctoral research at the University of Arizona. Subsequently, he taught at the University of Sarajevo and later chaired the department of management information system at the Economics Faculty.

Lagumdžija began his political career during the Bosnian War as deputy Prime Minister of the Republic of Bosnia and Herzegovina, advising then-president of the presidency Alija Izetbegović. He accompanied Izetbegović at almost all of the peace plan negotiations during the war. In the 2000 parliamentary election, the SDP BiH formed a coalition with the Party for Bosnia and Herzegovina to gain the majority and force the nationalist parties out of power. Lagumdžija became both the Minister of Foreign Affairs and Chairman of the Council of Ministers. The SDP BiH-led government facilitated the passage of the Election Law, a prerequisite to Bosnia and Herzegovina's accession to the Council of Europe. Lagumdžija's party led the government until the 2002 general election, when the nationalist parties were elected back into power. He then served as member of the national House of Representatives.

Elected president of the SDP BiH in 1997, Lagumdžija has played a key role in constitutional reform talks, most notably in those regarding the 2010–2012 government formation. Following the October 2010 general election and the SDP BiH's emergence as the largest party in the House of Representatives, a government was formed around the SDP BiH and the Alliance of Independent Social Democrats in January 2012. Subsequently, Lagumdžija was once again appointed Minister of Foreign Affairs and served until 2015. Following the 2014 general election and a poor showing of the SDP BiH, he resigned as party leader after seventeen years. In 2019, he was removed from the SDP BiH due to political activity in his own new political organization.

Lagumdžija is a member of the Club of Madrid, an independent non-profit organization created to promote democracy and change in the international community.

Education Lagumdžija earned his high school diploma as a part of the Youth For Understanding exchange student program in Allen Park, Michigan in 1973.

His subsequent education was at the University of Sarajevo, where he earned a BS in 1977, an MS in 1981 and a PhD in 1988 in the field of Computer science and Electrical engineering.

In 1989, as a Fulbright Program participant, Lagumdžija did postdoctoral research at the University of Arizona in the Department of Management Information Systems and the Center for the Management of Information.

Academic career Lagumdžija began teaching at the University of Sarajevo in 1989 as a professor of management information system and informatics at the Economics Faculty and Projected Information Systems and Group Support Systems at the Electrical Engineering Faculty.

He served as the chair of the department of Management and Information Systems at the Economics Faculty since 1994 and the director of the director of the Management and Information Technologies Center (an organizational unit of the Economics Faculty) since 1995.

Lagumdžija's particular academic interests lie in the areas of Group Support Systems and management information systems. He is the author of six books and over a hundred papers in the field of management information systems.

At the end of the Bosnian War, Lagumdžija helped to secure funds from the Soros Foundation with which to rebuild the Group Support System facility at the University of Sarajevo. To create the facility, he worked with Douglas Vogel and Mark Adkins from the University of Arizona where generations of group support systems software and facilities have been built.Jay Nunamaker, Robert Briggs, Daniel Mittleman, Douglas Vogel, Pierre Balthhazard, "" Journal of Management Information Systems, Vol. 13, No. 3, Information Technology and Its Organizational Impact, pp. 163-207 (45 pages), (Winter, 1996/1997). The strategic objective of the Management and Information Technologies Center, which housed the GSS facility, was to "assist and promote the transition of Bosnia and Herzegovina to a democratic, market-driven economy."Zlatko Lagumdzija, Mark Adkins, Doug Vogel, "Rebuilding Sarajevo Using Partnerships" hicss, pg. 479, 30th Hawaii International Conference on System Sciences (HICSS) Volume 2: Information Systems Track-Collaboration Systems and Technology, 1997.

As part of that mandate, the Center held sessions for key business and government leaders as well as students at the University of Sarajevo utilizing GSS technology to assist them in thinking about and planning for the economic reconstruction of Sarajevo.

Political career Wartime political career Lagumdžija began his political career during the Bosnian War as deputy prime minister, and was also an adviser to then-president of the presidency Alija Izetbegović.

In one particular case, Lagumdžija advised Izetbegović not to sign the Vance–Owen Peace Plan: "Mr Izetbegović was not endorsing it, but thinking out loud and saying perhaps the plan would not be so bad, that we could live with it. And some of us told him, 'Anyone who signs this plan will be dead, and not just politically…'" he told a New York Times reporter in February 1993.Gelb, Leslie H. "Sarajevo, Dead and Alive. [Op-Ed]" The New York Times, 7 February 1993, pg. E21.

Izetbegović signed the peace plan in March 1993. In May 1992, Lagumdžija was with Izetbegović, Izetbegović’s daughter Sabina and his bodyguard, returning from the Lisbon negotiations, when they were surrounded at the Sarajevo International Airport by the Yugoslav People's Army, kidnapped and driven in a convoy to Lukavica, in Serb-held territory.

In April 1993, Lagumdžija met with a group of citizens from Srebrenica who had journeyed through the Serb lines to Sarajevo. They informed him of the desperate situation of Srebrenica and the eastern Bosnian enclaves. In an effort to highlight the plight of Srebrenica, Lagumdžija suspended humanitarian aid donations for Sarajevo until aid was delivered to the eastern enclaves. A month later, United Nations (UN) Commander Philippe Morillon visited Srebrenica and declared the citizens under the protection of the UN.

Post-war political career

As a member of the Social Democratic Party (SDP BiH), Lagumdžija served as member of the national House of Representatives from 2002 to 2012. He was the president of the SDP BiH from 1997 to 2014.

In the 2000 parliamentary election, the SDP BiH formed a coalition with the Party for Bosnia and Herzegovina, a party founded and led by former wartime prime minister Haris Silajdžić, to gain the majority and force the nationalist parties out of power. They gathered a coalition of many other small parties to create the "Alliance for Change". Lagumdžija became the Foreign Minister, a post he served in from 2001 until 2002, and Chairman of the Council of Ministers, serving until 2002. After protracted negotiations, disagreements and delays, he signed the Agreement on Succession Issues of the Former Socialist Federal Republic of Yugoslavia on behalf of Bosnia and Herzegovina.

When the SDP BiH came into political power on a platform of economic reform and anti-corruption, Lagumdžija was lauded by the Western powers as the hopeful "face of a pluralistic, united Bosnia."Kaminski, Matthew. "The West’s man in Bosnia", Wall Street Journal, 28 June 2000: A16. The SDP BiH-led government facilitated the passage of the Election Law, which was not only an important step towards democracy, but also a prerequisite to Bosnia's accession to the Council of Europe. The SDP BiH led the coalition government until the October 2002 general election, when the public, dissatisfied at the pace of political reform, elected the nationalist parties back into power.

On 18 May 2019, Lagumdžija was removed from the SDP BiH due to his political activity in his own new political organization, the Social Democratic Movement, which was in the process of being founded, and which was also supported by Bosnian Presidency member and former SDP BiH vice-president Željko Komšić.

In January 2023, Bosnian Presidency member Denis Bećirović nominated Lagumdžija to serve as the Permanent Representative of Bosnia and Herzegovina to the United Nations. On 6 July 2023, he presented his credentials to UN secretary-general António Guterres and assumed office.

2010–2012 government formation

Following the 2010 general election, a process of formation of Bosnia and Herzegovina's Council of Ministers (i.e. the national government) had begun. The resulting election produced a fragmented political landscape without a coalition of a parliamentary majority more than a year after the election. The SDP BiH, led by Lagumdžija, and the Bosnian Serb autonomist Alliance of Independent Social Democrats (SNSD), each had 8 MPs of the total 42 MPs of the House of Representatives.

The major Croat (HDZ BiH and HDZ 1990) and Serb parties (SNSD and SDS) contended that a gentlemen's agreement existed in which the chairmanship of the Council of Ministers rotates between the three constitutional nationalities. In this case, it would be the turn for a Croat politician to chair the Council. As the Croatian Democratic Union (HDZ BiH) and the Croatian Democratic Union 1990 (HDZ 1990) received the overwhelming share of Croat votes in the 2010 general election, the parties demanded that a member of one of them receive the position of Chairman. The SDP BiH on the other hand, claimed that the only necessity is the ethnicity of the individual, and not the party, demanding the right to appoint a Croat Chairman from SDP BiH ranks, calling upon the right of having assumed most votes nationwide.

The European Union and the Office of the High Representative repeatedly attempted negotiations to appease the Bosniak–Bosnian and Serb–Croat divided political blocs, in parallel to the Bosnian constitutional crisis, all ending in failure. The Bosniak-Bosnian coalition insisted that the seat would have to go to them as the party that received the largest number of votes, while the Serb–Croat alliance insisted that due to the fact that according to tradition, the next Chairman of the Council of Ministers must be an ethnic Croat, it must come from an authentic Croat party (Croatian Democratic Union), and not the multi-ethnic SDP BiH.

A round of talks between party leaders was held in Mostar on 5 September 2011, hosted by Croat politicians Božo Ljubić and Dragan Čović, with Milorad Dodik, Mladen Bosić, Sulejman Tihić and Lagumdžija in attendance.
