The city of Baqubah, the capital of Iraq's Diyala province, has a long and rich history rooted in pre-Islamic times. It is believed that a settlement existed on its site even before the Common Era, and the name itself comes from the Aramaic words "Beth" (house) and "Aquba," which can be translated as "house of the guard." The first significant mentions of Baqubah date back to the Abbasid Caliphate era, when the city served as an important point on the trade route from Baghdad to Khurasan.
The city's prosperity was bolstered by its strategic location and fertile lands. Situated approximately 50 km northeast of Baghdad on the Diyala River, Baqubah was historically a vital transit point on a branch of the Great Silk Road. This made it a significant center for trade in agricultural products and livestock. Economic well-being was ensured by advanced agriculture: during the Abbasid era, the region, irrigated by the waters of the Nahrawan Canal, was famous for its date groves and fruit orchards.
In the Middle Ages, Baqubah was not only a thriving trading city but also the administrative center of the Upper Nahrawan district. Its economy was closely tied to the cultivation of dates, lemons, and pomegranates. This centuries-old agricultural tradition has survived to this day, and today Baqubah is known as the primary center for orange cultivation in all of Iraq. Due to its location, the city also held key strategic importance, earning the unofficial title of the "Eastern Gate of Baghdad."
