From wikipedia:
Aleppo (Arabic: حلب‎ ['ħalab], is a city in northern Syria, capital of the Aleppo Governorate; the Governorate extends around the city for over 16,000 km² and has a population of 4,393,000, making it the largest Governorate in Syria (followed by Damascus). Aleppo is one of the oldest inhabited cities in the world; it knew human settlement since the eleventh millennium B.C. through the residential houses that were discovered in Tell Qaramel. It was known to antiquity as Khalpe, Khalibon, to the Greeks as Beroea, and to the Turks as Halep. During the Crusades, and again during the French Mandate, the name Alep was used: "Aleppo" is an Italianised version of this. It occupies a strategic trading point midway between the Mediterranean Sea and the Euphrates. Initially, Aleppo was built on a small group of hills surrounding the prominent hill where the castle is erected. The small river Quwēq (قواق) runs through the city.

The ancient name of Aleppo, Halab, is of obscure origin. Some have proposed that Halab means 'iron' or 'copper' in Amorite languages since it was a major source of these metals in antiquity. Halaba in Aramaic means white, referring to the color of soil and marble abundant in the area. Another proposed etymology is that the name Halab means "gave out milk," coming from the ancient tradition that Abraham gave milk to travelers as they moved throughout the region. The colour of his cows was ashen (Arab. shaheb), therefore the city is also called "Halab ash-Shahba'" (he milked the ash-coloured).

Because the modern city occupies its ancient site, Aleppo has scarcely been touched by archaeologists. The site has been occupied from around 5000 BC, as excavations in Tallet Alsauda show. It grew as the capital of the kingdom of Yamkhad until the ruling Amorite Dynasty was overthrown around 1600 BC. The city remained under Hittite control until perhaps 800 BC before passing through the hands of the Assyrians and the Persian Empire and being captured by the Greeks in 333 BC, when Seleucus Nicator renamed the settlement Beroea, after Beroea in Macedon. The city remained in Greek or Seleucid hands until 64 BC, when Syria was conquered by the Romans.

The city remained part of the Eastern Roman or Byzantine Empire before falling to Arabs under Khalid ibn al-Walid in 637. In 944, it became the seat of an independent Emirate under the Hamdanid prince Sayf al-Daula, and enjoyed a period of great prosperity, being home to the great poet al-Mutanabbi and the philosopher and polymath al-Farabi. The city was sacked by a resurgent Byzantine Empire in 962, while Byzantine forces occupied it briefly from 974 to 987. The city and its Emirate became an Imperial vassal until the Byzantine-Seljuk Wars. The city was twice besieged by Crusaders — in 1098 and in 1124 — but was not conquered.

The main role of the city was as a trading place, as it sat at the crossroads of two trade routes and mediated the trade from India, the Tigris and Euphrates regions and the route coming from Damascus in the South, which traced the base of the mountains rather than the rugged seacoast. Although trade was often directed away from the city for political reasons, it continued to thrive until the Europeans began to use the Cape route to India and later to utilize the route through Egypt to the Red Sea. Since then the city has declined and its chief exports now are the agricultural products of the surrounding region, mainly wheat, cotton, pistachios, olives, and sheep.
