World leaders mourned the death of Pope John Paul tonight, some hailing him as a force for peace across the globe while others said he played a major role in the fall of the Iron Curtain.
"The Catholic Church has lost its shepherd. The world has lost a champion of human freedom and a good and faithful servant of God has been called home," said US President George W Bush.
"Pope John Paul II was himself an inspiration to millions of Americans and to so many more throughout the world."
UN Secretary General Kofi Annan said the Pope was a man of peace and had been a great supporter of the United Nations.
"He ... (was) extremely concerned about the world we lived in, and like me, he also felt that in war, all are losers," said Mr Annan.
Mr Lech Walesa, who led Poland's Solidarity movement which won power after a decade of struggle and hastened the collapse of the whole Soviet bloc, said Polish-born John Paul inspired the drive to end communism in Eastern Europe.
"(Without him) there would be no end of communism or at least much later and the end would have been bloody," Mr Walesa said.
German Chancellor Gerhard Schroeder said: "Pope John Paul II wrote history. By his efforts and through his impressive personality, he changed our world."
Bracing for his passing, faithful round the world had gathered in prayer this week for the Pope, who led the Catholic Church for 26 years -- the third-longest pontificate - and visited more countries than any predecessor.
The faithful in Europe, Asia, Africa and the Americas said special prayers for the man who revitalised the Church and brought his vision of Christianity to the masses.
China, which does not allow its Catholics to recognise the Vatican's authority, had taken the unusual step of expressing concern over the Pope's health and had said it hoped he would recover.
Mr Bobby Brown, Israel-based international director of the World Jewish Congress, said the Catholic Church had become an ally of the Jewish people under the Pope after 2,000 years of Christian-Jewish hostility.
In 1993, the Vatican forged full diplomatic ties with Israel.
"There is a shattering difference between the Catholic church of 20 to 50 years ago to today," said Mr Brown.
Bells tolled at Bethlehem's Church of the Nativity, the traditional birthplace of Jesus, after news of the Pope's death.
