The collapse of its governing coalition is an extraordinary moment for Germany, a country known for stable governments. It has happened only twice before in the 75 years since the modern state was founded.

But like a marriage that has finally ended after years of fighting, the spectacular breakup on Wednesday night of Chancellor Olaf Scholz’s three-party coalition was expected by most and welcomed by many.

A recent national poll found that a majority of Germans wanted to end the “traffic light” coalition, named for the colors of the parties that made it up — red for the Social Democratic Party, yellow for the pro-business Free Democratic Party and green for the Greens. Only 14 percent still had confidence in the coalition, according to the same poll.

Although the opposition is pushing for Mr. Scholz to end the government sooner, Wednesday’s announcement will very likely lead to early elections in March, at a precarious time for Germany both domestically and internationally.

Here’s what we know about the collapse of the coalition.

How did we get here?

On Wednesday night, Mr. Scholz fired his finance minister, Christian Lindner, who is the head of the Free Democrats, over disagreements about the 2025 budget and the economy in general. That precipitated the end of the coalition.

The coalition was initially both successful and popular. But a constitutional court ruling late in 2023, barring the government from repurposing finances left over from the pandemic, spelled the beginning of the end.
