Aleppo (Arabic: حلب‎ Ḥalab [ˈħalæb], other names) is the largest city in Syria and the capital of Aleppo Governorate, the most populous Syrian governorate. With an official population of 2,132,100 (2004 census), it is also one of the largest cities in the Levant. For centuries, Aleppo was Greater Syria's largest city and the Ottoman Empire's third, after Constantinople and Cairo. Although relatively close to Damascus in distance, Aleppo is distinct in identity, architecture and culture, all shaped by a markedly different history and geography.

Aleppo is one of the oldest continuously inhabited cities in the world; it has been inhabited since perhaps as early as the 6th millennium BC. Excavations at Tell as-Sawda and Tell al-Ansari, just south of the old city of Aleppo, show that the area was occupied since at least the latter part of the 3rd millennium BC; and this is also when Aleppo is first mentioned in cuneiform tablets unearthed in Ebla and Mesopotamia, in which it is noted for its commercial and military proficiency. Such a long history is probably due to its being a strategic trading point midway between the Mediterranean Sea and Mesopotamia.

Syria (/ˈsɪriə/ ( listen) SIRR-ee-ə; Arabic: سورية‎ Sūriyya or سوريا Sūryā; Syriac: ܣܘܪܝܐ; Kurdish: Sûrî), officially the Syrian Arab Republic (Arabic: الجمهورية العربية السورية‎ al-Jumhūriyyah al-‘Arabīyah as-Sūriyyah  Arabic pronunciation (help·info)), is a country in Western Asia, bordering Lebanon and the Mediterranean Sea to the West, Turkey to the north, Iraq to the east, Jordan to the south, and Israel to the southwest.

In English, the name Syria was formerly synonymous with the Levant, known in Arabic as Sham, while the modern state encompasses the sites of several ancient kingdoms and empires, including the Eblan civilization of the third millennium BC. In the Islamic era, its capital city, Damascus, the oldest continuously inhabited city in the world, was the seat of the Umayyad Caliphate, and a provincial capital of the Mamluk Sultanate of Egypt.

The population of Syria is 74% Sunni, 12% Alawi, 10% Christian, and 3% Druze. Combined, 87% of the Syrian population is Muslim, while the other 10% is Christian, which includes mainly Arab Christians but also Assyrians and Armenians. Major ethnic minorities in Syria include Kurds (9%), Assyrians, Armenians, Turkmens and Circassians. The majority of the population is Arab (90%).
