(Reuters) - The European Union won the Nobel Peace Prize on Friday for promoting peace, democracy and human rights over six decades in an award seen as a morale boost as the bloc struggles to resolve its economic crisis.

The award served as a reminder that the EU had largely brought peace to a continent which tore itself apart in two world wars in which tens of millions died.

The EU has transformed most of Europe “from a continent of wars to a continent of peace,” Nobel Committee Chairman Thorbjoern Jagland said in announcing the award in Oslo.

“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.”

Jagland praised the EU for rebuilding Europe from the devastation of World War Two and for its role in spreading stability after the fall of the Berlin Wall in 1989.

While welcomed by European leaders, the award will have little practical effect on the debt crisis afflicting the single currency zone, which has brought economic instability and social unrest to several states with rioting in Athens and Madrid.
