Aleppo is a city in Syria, serving as the capital of the Aleppo Governorate, the most populous Syrian governorate. With an official population of 4.6 million in 2010, Aleppo was the largest Syrian city before the Syrian Civil War; however, now Aleppo is likely the second-largest city in Syria after the capital Damascus.
Aleppo is an ancient city, and one of the oldest continuously inhabited cities in the world; it may have been inhabited since 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 by Amorites since at least the latter part of the 3rd millennium BC. This is also when Aleppo is first mentioned in cuneiform tablets unearthed in Ebla and Mesopotamia, in which it is a part of the Amorite state of Yamhad, and is noted for its commercial and military proficiency. Such a long history is attributed to its strategic location as a trading center midway between the Mediterranean Sea and Mesopotamia (i.e. modern Iraq).
For centuries, Aleppo was the largest city in the Syrian region, and the Ottoman Empire's third-largest after Constantinople and Cairo. It was also one of the largest cities in the Levant before the advent of the Syrian Civil War. The city's significance in history has been its location at one end of the Silk Road, which passed through central Asia and Mesopotamia. When the Suez Canal was inaugurated in 1869, trade was diverted to sea and Aleppo began its slow decline. At the fall of the Ottoman Empire after World War I, Aleppo ceded its northern hinterland to modern Turkey, as well as the important railway connecting it to Mosul. In the 1940s, it lost its main access to the sea, Antakya and İskenderun, also to Turkey. Finally, the isolation of Syria in the past few decades further exacerbated the situation. This decline may have helped to preserve the old city of Aleppo, its medieval architecture and traditional heritage. It won the title of the "Islamic Capital of Culture 2006", and has had a wave of successful restorations of its historic landmarks.
During the Battle of Aleppo, the city suffered massive destruction, and has been the worst-hit city in the Syrian Civil War. In December 2016, the Syrian government achieved full control of Aleppo following a successful offensive.
