OSLO, Norway (AP) — The European Union won the Nobel Peace Prize today for its efforts to promote peace and democracy in Europe — an award given even though the bloc is struggling with its biggest crisis since it was created in the 1950s.

The Norwegian prize committee said the EU was being honored for six decades of contributions “to the advancement of peace and reconciliation, democracy and human rights in Europe.”

“The stabilizing part played by the European Union has helped to transform a oncetorn Europe from a continent of war to a continent of peace,” Nobel committee chairman Thorbjoern Jagland said.

The EU grew out of the tremendous devastation of World War II, fueled by the conviction that ever-closer economic ties would make sure that century-old enemies never turned on each other again. It’s now made up of 500 million people in 27 nations, with other nations lined up, waiting to join.

But the European project is now facing its greatest challenge yet — a debt crisis that has stirred deep tensions between north and south, caused unemployment to soar across the bloc and is threatening the euro, the currency used by 17 of its members.

Social media exploded with strong reactions today, both for and against, in awarding the prize — worth 8 million Swedish kronor ($1.2 million).

“The EU is an unique project that replaced war with peace, hate with solidarity. Overwhelming emotion for awarding of Nobel prize to EU,” Martin Schulz, president of the European Parliament, wrote in a tweet.

“Nobel prize for the EU. At a time Brussels and all of Europe is collapsing in misery. What next? An Oscar for Van Rompuy?” said Dutch euro-skeptic lawmaker Geert Wilders, referring to Herman Van Rompuy, president of the European Council.

The idea of a united Europe began to take on a more defined shape when, on May 9, 1950, French Foreign Minister Robert Schuman proposed that France and the Federal Republic of Germany pool their coal and steel resources in a new organization that other European countries could join.

“Today, war between Germany and France is unthinkable. This shows how, through well-aimed efforts and by building up mutual confidence, historical enemies can become close partners,” the committee said.

The citation also noted the democratic conditions the EU has demanded of all those nations waiting to join, referred to Greece and Spain when they joined in 1980 after dictatorships, and to the countries in Eastern Europe who sought EU membership after the 1989 fall of the Berlin Wall.

“The EU is currently undergoing grave economic difficulties and considerable social unrest,” Jagland said. “The Norwegian Nobel Committee wishes to focus on what it sees as the EU’s most important result: the successful struggle for peace and reconciliation and for democracy and human rights.”

It was not yet clear who would accept the prize for the EU.

The EU has been seen as a possible candidate for the Nobel for many years, and the members of the committee had previously praised the community’s significance as a promoter of peace and democracy in Europe.
