Alexander De Croo

Alexander De Croo was born on November 3, 1975, in Vilvoorde, a town just north of Brussels in the Flemish province of Flemish Brabant ^[1]. Politics ran deep in his family. His father, Herman De Croo, was one of the most durable figures in Belgian liberalism, a long-serving minister and later president of the Chamber of Representatives. Growing up in that household gave the younger De Croo an early education in the mechanics of Belgian coalition politics, even though he initially chose a different path ^[2].

He studied commercial engineering at the Vrije Universiteit Brussel, graduating in the late 1990s, and later completed an MBA at the Kellogg School of Management at Northwestern University in the United States ^[1]. Rather than entering politics straight away, he joined the Boston Consulting Group, where he worked as a strategy consultant on projects across Europe. In 2006 he founded Darts-ip, a company that built a database of intellectual property case law used by lawyers and corporations to track litigation worldwide ^[2].

Those years in business shaped his later political identity. De Croo presented himself as a manager and problem solver rather than a career politician, a framing that would matter when he made his move into public life at a moment of crisis for his party.

De Croo entered electoral politics in 2009 as a candidate for the Flemish liberal party Open VLD in the European elections. He did not win a seat, but the campaign raised his profile, and in December 2009 party members elected him leader of Open VLD, a striking result for a newcomer in his mid-thirties ^[3]. Anyone asking who was Alexander De Croo before Belgium knew his name usually starts here: an untested party chief handed a party in decline.

His leadership had immediate consequences. In April 2010 he withdrew Open VLD from the governing coalition of Prime Minister Yves Leterme over the long-running dispute about the Brussels-Halle-Vilvoorde electoral district, a decision that brought down the government and triggered elections ^[3]. The vote that followed opened the longest government formation in Belgian history, with the country going 541 days without a full federal cabinet.

De Croo stepped down as party leader after disappointing election results but rebuilt his career in government. In 2012 he became Deputy Prime Minister and Minister of Pensions in the cabinet of Elio Di Rupo. From 2014 he served under Charles Michel as Deputy Prime Minister with responsibility for development cooperation, the digital agenda, telecommunications, and postal services ^[1]. When the Flemish nationalist N-VA left the Michel government in December 2018 in a dispute over the UN migration compact, De Croo took over the finance portfolio, holding it until 2020 ^[4].

The federal election of May 2019 produced a deeply fragmented parliament, and Belgium again spent well over a year without a fully empowered government. Negotiations dragged through the first waves of the COVID-19 pandemic, managed in the interim by a caretaker cabinet under Sophie Wilmes. In late September 2020, seven parties finally agreed on a program: liberals, socialists, and greens from both language communities, plus the Flemish Christian Democrats. The press nicknamed it the Vivaldi coalition, after the composer of The Four Seasons, a nod to its four political families ^[4].

On October 1, 2020, Alexander De Croo was sworn in as Prime Minister of Belgium before King Philippe ^[4]. His appointment was in some ways a compromise: Open VLD was not the largest party in the coalition, but De Croo was acceptable across the linguistic and ideological divides. He became the first Flemish liberal to hold the office since Guy Verhofstadt left it in 2008.

His first task was the pandemic. Belgium had recorded one of the highest per capita COVID-19 death tolls in the world during 2020, and the new government tightened restrictions that autumn as a second wave hit ^[5]. Over the following year the country carried out one of the European Union's faster vaccination campaigns, and De Croo's cabinet gradually shifted from lockdown management to economic recovery.

Among the most cited Alexander De Croo achievements is his handling of the energy shock that followed Russia's full-scale invasion of Ukraine in February 2022. Belgium, heavily dependent on imported gas, faced surging prices, and his government introduced support packages for households while pushing at the European level for joint responses to the crisis ^[5]. In 2022 the coalition also reversed course on nuclear power, agreeing with the operator Engie to extend the lives of the Doel 4 and Tihange 3 reactors by ten years, a significant amendment to Belgium's long-standing nuclear phase-out law ^[5].

De Croo positioned Belgium firmly behind Ukraine. His government committed F-16 fighter jets to Kyiv, hosted training and support programs, and championed the use of proceeds from frozen Russian assets, a matter of particular weight for Belgium because the Euroclear settlement house in Brussels holds a large share of those immobilized funds ^[6]. In the first half of 2024 he presided over Belgium's rotating presidency of the Council of the European Union, steering final negotiations on several major legislative files, including the EU's artificial intelligence act, before the European elections that June ^[6].

Before reaching the premiership he had already built an international reputation on gender equality. As development minister he helped launch SheDecides, a global initiative created in 2017 to fund sexual and reproductive health programs after the United States cut such funding ^[7]. In 2019 he published a book, De eeuw van de vrouw, released in English as The Age of Women, arguing that closing gender gaps benefits men as well as women ^[7]. These commitments are among the Alexander De Croo facts that distinguish him from most heads of government of his generation.

The federal election of June 9, 2024, ended De Croo's premiership. Open VLD suffered heavy losses, falling to single digits in Flanders, while the Flemish nationalist N-VA of Bart De Wever finished first. On election night De Croo announced, visibly emotional, that he would resign as prime minister and take responsibility for his party's defeat ^[8].

Belgian coalition building is rarely quick, and De Croo stayed on for months as head of a caretaker government while five parties negotiated a new majority. During that period he continued to represent Belgium at European Council summits and NATO meetings, including the alliance's seventy-fifth anniversary summit in Washington in July 2024 ^[8].

The new government took office on February 3, 2025, when Bart De Wever was sworn in as prime minister at the head of the so-called Arizona coalition ^[8]. De Croo handed over after more than four years in office, a tenure that spanned a pandemic, a land war in Europe, and an energy crisis, and he returned to his seat in the Chamber of Representatives.

De Croo is married to Annik Penders, and the couple have two sons ^[2]. The family settled in Michelbeke, a village in the municipality of Brakel in East Flanders, the rural constituency long associated with his father. He is a Dutch speaker who moves easily between Dutch, French, and English, a practical asset in a country where prime ministers must address two large language communities and an international press corps in Brussels ^[2].

Colleagues and journalists have often described him as data-driven and managerial in style, more comfortable with spreadsheets and policy detail than with the theatrical side of politics ^[4]. He is a keen cyclist, a common pastime in the Flemish Ardennes where he lives, and has spoken publicly about balancing family life with the demands of office.

De Croo's place in Belgian political history rests on continuity under pressure. He took office during a public health emergency, at the end of the country's second marathon government formation in a decade, and kept an unwieldy seven-party coalition together for a full parliamentary term, something few observers predicted in 2020 ^[4]. His government's decisions on nuclear energy, defense spending, and support for Ukraine reshaped Belgian policy in ways his successors inherited rather than reversed ^[5].

Internationally, he is remembered for Belgium's 2024 EU Council presidency and for a foreign policy that combined strong Atlanticism with occasional independence, including his willingness to criticize partners over the conduct of the war in Gaza ^[6]. His advocacy on gender equality, from SheDecides to The Age of Women, gave him a profile beyond the usual portfolio of a Belgian prime minister ^[7].

For his party the story is more complicated. Open VLD entered his premiership as a governing force in Flanders and left it much diminished, and the 2024 defeat forced a rebuilding effort in which De Croo, still in his forties as he left office, remains one of Flemish liberalism's most recognizable figures ^[8].
