In office so long she was dubbed Germany’s “eternal chancellor”, Merkel, 67, leaves with her popularity so resilient she would likely have won a record fifth term had she sought it.
Instead, Merkel will pass the baton as the first German chancellor to step down entirely by choice, with a whole generation of voters never knowing another person at the top.
Her supporters say she provided steady leadership through countless global crises as a moderate and unifying figure.
Yet critics argue a muddle-through style pegged to the broadest possible consensus lacked the bold vision to prepare Europe and its top economy for the coming decades.
What is certain is that she leaves behind a fractured political landscape, with her own CDU party divided as it struggles to emerge from her long shadow.
Social Democrat Olaf Scholz, who served as her vice chancellor and finance minister, successfully sold himself as the Merkel continuity candidate in the run-up to September’s general election and will now succeed her.
With Scholz due to be officially elected by parliament as chancellor on Wednesday, Merkel will fall just days short of beating Helmut Kohl’s record as Germany’s longest-serving post-war leader.
Do the right thing
The unflappable Merkel has served for many in recent years as a multilateralist counterweight to the big, brash men of global politics, from Donald Trump to Vladimir Putin.
A Pew Research Center poll in September showed large majorities in most democracies around the globe having “confidence in Merkel to do the right thing in world affairs”.
A trained quantum chemist raised behind the Iron Curtain, Merkel was long in sync with her change-averse electorate as a guarantor of stability.
Her major policy shifts reflected the wishes of large German majorities — among them phasing out nuclear power after the 2011 Fukushima disaster — and attracted a broad new coalition of women and urban voters to the once arch-conservative CDU.
However, the last days of her tenure have been marred by a vicious fourth wave of coronavirus, the worst since the start of the pandemic.
Before the pandemic, her boldest move — keeping open German borders to more than one million asylum seekers in 2015 — seemed set to determine her legacy.
But while many Germans rallied to Merkel’s “We can do it” cry, the move also emboldened an anti-migrant party, Alternative for Germany (AfD), ushering a far-right bloc into parliament for the first time since World War II.
The woman once known as the “climate chancellor” for pushing renewables also faces a mass movement of young activists arguing she has failed to deal with the climate emergency, with Germany not meeting its own emission-reduction commitments.
The incoming coalition has pledged to improve on that legacy and to take a more assertive stance with Russia and China after the commerce-based pragmatism of the Merkel years.
Merkel became Europe’s go-to leader during the eurozone crisis when Berlin championed swingeing spending cuts in return for international bailout loans for debt-mired countries.
Angry protesters dubbed her Europe’s “austerity queen” and caricatured her in Nazi garb, while defenders credit her with holding the currency union together.
Kohl’s ‘girl’ to ‘Mummy’
Merkel, the EU and the G7’s most senior leader, started as a contemporary of George W. Bush, Tony Blair and Jacques Chirac when she became Germany’s youngest and first female chancellor in 2005.
She was born Angela Dorothea Kasner on July 17, 1954 in the port city of Hamburg, the daughter of a Lutheran clergyman and a schoolteacher.
Her father moved the family to a small-town parish in the communist east at a time when tens of thousands were heading the other way.
She excelled in mathematics and Russian, which has helped her maintain dialogue with the other veteran on the world stage, Russia’s Putin, who was a KGB officer in Dresden when the Berlin Wall fell in 1989.
Merkel kept the name of her first husband, whom she married in 1977 and divorced five years later.
After the fall of the wall, Merkel, who was working in a chemistry lab, joined a pro-democracy group that would merge with Kohl’s Christian Democrats.
The Protestant from East Germany whom Kohl nicknamed his “girl” would later be elected leader of a party until then dominated by western Catholic patriarchs.
As she rose to power, party rivals sneeringly called her “Mutti” (Mummy) behind her back but she deftly — some said ruthlessly — eliminated potential challengers.
Although her name has come up on wish lists for key EU or United Nations posts, Merkel has said she will leave politics altogether.
Her four terms in office were “eventful and often very challenging years”, she said at a military ceremonial farewell. “They have challenged me politically and humanly and at the same time, they were also fulfilling.”
Asked on her final trip to Washington in June what she looked forward to most, she replied: “not having to constantly make decisions”.
