Pope Francis is to arrive Friday for the first-ever papal visit to conflict-torn Iraq, aiming to encourage the dwindling Christian community to remain in their ancient homeland and broaden his outreach to Islam.
Among the most extraordinary moments of the trip will be his one-on-one meeting with Grand Ayatollah Ali Sistani.
Despite a second deadly wave of coronavirus infections, renewed violence, and notoriously poor public services, Francis is fulfilling the dream of a predecessor, late pope John Paul II, by visiting Iraq.
Amid war and persecution, the country's Christian community -- one of the world's oldest -- has fallen from 1.5 million in 2003 to just 400,000 today.
The 84-year-old pontiff, who will be on his first foreign trip since the start of the pandemic, plans to voice solidarity with them and the rest of Iraq's 40 million people during a packed three-day visit.
From central Baghdad to the city of Najaf, welcome banners featuring his image and Arabic title "Baba al-Vatican" already dot the streets.
From Ur to ravaged Christian towns in the north, roads are being paved and churches rehabilitated in remote areas that have never seen such a high-profile visitor.
"The pope's message is that the Church stands beside those who suffer," said Najeeb Michaeel, Chaldean Catholic Archbishop of the northen city of Mosul.
"He will have powerful words for Iraq, where crimes against humanity have been committed."
- Ancient roots -
Iraq's Christian community is one of the oldest and most diverse in the world, with Chaldeans and other Catholics making up around half, along with Armenian Orthodox, Protestants, and others.
By 2003, when the US-led invasion toppled then-dictator Saddam Hussein, Christians made up around six percent of Iraq's 25 million people.
But even as sectarian violence pushed members of the minority to flee, the national population surged, further diluting Christians to just one percent, according to William Warda, co-founder of the Hammurabi Human Rights Organisation.
Most were concentrated in the northern province of Nineveh, where many still speak a dialect of Aramaic, the language of Jesus Christ.
In 2014, militants from the so-called ISIS group seized control of Nineveh, rampaging through Christian towns and telling residents: convert or die.
At the time, Pope Francis endorsed military action against ISIS and considered visiting northern Iraq in solidarity with Christians there.
That trip never materialized, but Francis has kept a close eye on Iraq, condemning the killing of unarmed protesters during mass anti-government rallies from 2019.
- A long time coming -
Pope John Paul II had planned to visit Iraq in 2000 but Saddam Hussein abruptly canceled the trip. His successor Benedict XVI never made moves towards Baghdad.
Soon after Francis was elected pope in 2013, he was urged to visit Iraq by Father Louis Sako -- later appointed as Cardinal and the head of the Chaldean Catholic Church and now a key organizer of the visit.
In 2019, President Barham Saleh extended an official invitation, hoping to help Iraq "heal" after years of violence.
But as the Covid-19 pandemic ravaged Italy, the pope canceled all foreign trips from June 2020.
He lands on Friday in Baghdad with a security team and accompanied by an entourage of 150 people, half of whom are journalists, who like the pope have already been vaccinated.
Just days ahead of the trip, the Vatican's ambassador to Iraq Mitja Leskovar tested positive for Covid-19, but officials insisted it would have "no impact" on the visit.
Despite the Covid situation, he will host masses in Baghdad, the Kurdish regional capital Arbil and Ur.
Swamped by some 4,000 new coronavirus cases per day, Iraq has imposed overnight curfews and full weekend lockdowns that will be extended to cover the entire visit.
Social distancing will be enforced at all church services and those hoping to attend had to register several weeks in advance.
Pope Francis is an outspoken proponent of interfaith efforts and has visited several Muslim-majority countries including Bangladesh, Turkey, Morocco, and the United Arab Emirates.
In Abu Dhabi in 2019, he met Sheikh Ahmed al-Tayeb, the imam of the Al-Azhar mosque in Cairo. They signed a document encouraging Christian-Muslim dialogue.
Francis hopes this week's trip could open a similar door to Shiite Muslims, who number roughly 200 million worldwide but are the majority in Iraq.
