Conservative leader Friedrich Merz was elected German Chancellor in the second round of parliamentary votes as his new alliance with center left-wing Social Democrats (SPD) was surprised in his first attempt.
Mel failed to win parliamentary support in the first round of votes, the first in Germany after the war.
Meiers won 325 votes in the second round of voting on Tuesday.
In a secret vote, he needed most of 316 of 630 votes, but received only 310 votes in the first round, far less than the 328 seats his league has.
After the vote, the 69-year-old headed to the nearby Bellevue Palace, which was officially nominated by Frank-Walter Steinmeier. Later, Meers would return to the historic Capitol building in the heart of Berlin, and was sworn in as Germany's tenth principal since the end of World War II.
The Conservative Alliance (CSU), led by Merz of the Christian Democratic Union (CDU) and the Christian Social Union (CSU), made the national election with 28.5% of the vote, but it still requires at least one alliance partner to form a majority government.
CDU/CSU reached a deal with the Social Democratic Party (SPD) on Monday that acquired a 16.4% stake in elections following the collapse of the Olaf Scholz administration last year.
Their agreement has already laid out plans to resume growth, such as lowering corporate taxes and lowering energy prices. This is also a strong support for Ukraine as it fights to repel Russian invasions and higher military spending.
The new secretary's bathroom will also include confrontational trade policies and domestic issues by U.S. President Donald Trump, such as the rise of the far-right, the anti-immigrant party's alternative to Germany (AFD).
Alliance "not united"
Al Jazeera's Dominic Kane, from Berlin, said Merz failed to win the first round of the vote, which showed that "in these three... nothing is good in managing the party right now".
"He (Melz) started with this new position and knew that his members of the league voted against him," he said.
Experts say Merz failed to win support for his prime ministerial status in his first attempt and he promised to restore German leadership on the world stage.
"The whole of Europe is fascinated by Berlin today and hopes that Germany can re-establish itself as an anchor for a stable and pro-European power," said Jana Puglierin, head of the Berlin office of the European diplomatic relations think tank. "Hope has been shattered. Outside our borders, the consequences."
Party insiders said on Monday that Melz will quickly gain a majority despite cabinet nominations on both coalition parties, policy compromises and huge lending packages that pushed the old parliament in the last few days.
"This shows that the alliance is not unified, which may weaken his policy capabilities," said Holger Schmieding, chief economist at Berenberg Bank in London.
Merz, who never served in the government office, had abrasives and unstable styles, also failed to convince some that he was the principal's material.
"The relationship between the two sides will be severely damaged due to this, and (it will) exacerbate the conflict that has already bubbling beneath the surface," said Philipp Koeker, a political scientist at the University of Hannover.
