During a trip to Syria, Pope John Paul II becomes the first pope to enter a mosque.

Pope John Paul II (Latin: Ioannes Paulus II; Italian: Giovanni Paolo II; Polish: Jan Pawe II; born Karol Jzef Wojtya [karl juzv vjtwa]; 18 May 1920 2 April 2005) was the head of the Catholic Church and sovereign of the Vatican City State from 1978 until his death in 2005. He was elected pope by the second papal conclave of 1978, which was called after John Paul I, who had been elected in August to succeed Pope Paul VI, died after 33 days. Cardinal Wojtya was elected on the third day of the conclave and adopted the name of his predecessor in tribute to him. Born in Poland, John Paul II was the first non-Italian pope since Adrian VI in the 16th century and the second-longest-serving pope after Pius IX in modern history.

John Paul II attempted to improve the Catholic Church's relations with Judaism, Islam, and the Eastern Orthodox Church. He maintained the Church's previous positions on such matters as abortion, artificial contraception, the ordination of women, and a celibate clergy, and although he supported the reforms of the Second Vatican Council, he was seen as generally conservative in their interpretation. He was one of the most travelled world leaders in history, visiting 129 countries during his pontificate. As part of his special emphasis on the universal call to holiness, he beatified 1,340 and canonised 483 people, more than the combined tally of his predecessors during the preceding five centuries. By the time of his death, he had named most of the College of Cardinals, consecrated or co-consecrated many of the world's bishops, and ordained many priests. He has also been credited with helping to end Communist rule in his native Poland as well as the rest of Europe.John Paul II's cause for canonisation commenced one month after his death with the traditional five-year waiting period waived. On 19 December 2009, John Paul II was proclaimed venerable by his successor, Benedict XVI, and was beatified on 1 May 2011 (Divine Mercy Sunday) after the Congregation for the Causes of Saints attributed one miracle to his intercession, the healing of a French nun called Marie Simon Pierre from Parkinson's disease. A second miracle was approved on 2 July 2013, and confirmed by Pope Francis two days later. John Paul II was canonised on 27 April 2014 (again Divine Mercy Sunday), together with John XXIII. On 11 September 2014, Pope Francis added these two optional memorials to the worldwide General Roman Calendar of saints. It is traditional to celebrate saints' feast days on the anniversary of their deaths, but that of John Paul II (22 October) is celebrated on the anniversary of his papal inauguration. Posthumously, he has been referred to by some Catholics as "St. John Paul the Great", although the title has no official recognition.

Syria (Arabic: سُورِيَا or سُورِيَة, Sūriyā), officially the Syrian Arab Republic (Arabic: ٱلْجُمْهُورِيَّةُ ٱلْعَرَبِيَّةُ ٱلسُّورِيَّةُ, romanized: al-Jumhūrīyah al-ʻArabīyah as-Sūrīyah), is a country in Western Asia. Syria borders the Mediterranean Sea to the west, Turkey to the north, Iraq to the east and southeast, Jordan to the south, and Israel and Lebanon to the southwest. Cyprus lies to the west across the Mediterranean Sea. A country of fertile plains, high mountains, and deserts, Syria is home to diverse ethnic and religious groups, including the majority Syrian Arabs, Kurds, Turkmens, Assyrians, Armenians, Circassians, Mandaeans, and Greeks. Religious groups include Sunnis, Christians, Alawites, Druze, Isma'ilis, Mandaeans, Shiites, Salafis, and Yazidis. The capital and largest city of Syria is Damascus. Arabs are the largest ethnic group, and Sunnis are the largest religious group.

Syria is a unitary republic consisting of 14 governorates and is the only country that politically espouses Ba'athism. It is a member of one international organization other than the United Nations, the Non-Aligned Movement; it was suspended from the Arab League in November 2011 and the Organisation of Islamic Cooperation, and self-suspended from the Union for the Mediterranean.The name "Syria" historically referred to a wider region, broadly synonymous with the Levant, and known in Arabic as al-Sham. The modern state encompasses the sites of several ancient kingdoms and empires, including the Eblan civilization of the 3rd millennium BC. Aleppo and the capital city Damascus are among the oldest continuously inhabited cities in the world. In the Islamic era, Damascus was the seat of the Umayyad Caliphate and a provincial capital of the Mamluk Sultanate in Egypt.

The modern Syrian state was established in the mid-20th century after centuries of Ottoman rule, and after a brief period as a French mandate, the newly created state represented the largest Arab state to emerge from the formerly Ottoman-ruled Syrian provinces. It gained de jure independence as a parliamentary republic on 24 October 1945, when the Republic of Syria became a founding member of the United Nations, an act which legally ended the former French Mandate, although French troops did not leave the country until April 1946.

The post-independence period was tumultuous, with many military coups and coup attempts shaking the country from 1949 to 1971. In 1958, Syria entered a brief union with Egypt called the United Arab Republic, which was terminated by the 1961 Syrian coup d'état. The republic was renamed as the Arab Republic of Syria in late 1961 after the December 1 constitutional referendum of that year, and was increasingly unstable until the 1963 Ba'athist coup d'état, since which the Ba'ath Party has maintained its power. Syria was under Emergency Law from 1963 to 2011, effectively suspending most constitutional protections for citizens.

Bashar al-Assad has been president since 2000 and was preceded by his father Hafez al-Assad, who was in office from 1971 to 2000. Throughout his rule, Syria and the ruling Ba'ath Party have been condemned and criticized for various human rights abuses, including frequent executions of citizens and political prisoners, and massive censorship. Since March 2011, Syria has been embroiled in a multi-sided civil war, with a number of countries in the region and beyond involved militarily or otherwise. As a result, a number of self-proclaimed political entities have emerged on Syrian territory, including the Syrian opposition, Rojava, Tahrir al-Sham and the Islamic State group. Syria was ranked last on the Global Peace Index from 2016 to 2018, making it the most violent country in the world due to the war. The conflict has killed more than 570,000 people, caused 7.6 million internally displaced people (July 2015 UNHCR estimate) and over 5 million refugees (July 2017 registered by UNHCR), making population assessment difficult in recent years.
