Azerbaijan–Iran border

Azerbaijan–Iran border is an international border between Azerbaijan and Iran, stretching for approximately 689 kilometers (428 miles) from the Caspian Sea in the east to the Aras River in the west, forming a boundary between the South Caucasus and Western Asia. The border passes through the Azerbaijani regions of Astara Rayon, Lankaran Rayon, Imishli Rayon, Babek Rayon, and Ordubad Rayon, as well as the Iranian provinces of East Azerbaijan Province, Ardabil Province, and West Azerbaijan Province, near cities like Baku, Tabriz, and Nakhchivan. The border is also close to the Nagorno-Karabakh region, which is claimed by Armenia and Azerbaijan, and has been a source of tension between Azerbaijan and Armenia, with Russia, Turkey, and Iran playing important roles in the Nagorno-Karabakh conflict.

Geography

The Azerbaijan-Iran border is characterized by diverse landscapes, including the Caspian Sea coast, the Talysh Mountains, and the Aras River valley, which forms a natural boundary between the two countries. The border region is home to several important rivers, including the Aras River, Kura River, and Araz River, which flow into the Caspian Sea and support agriculture and industry in the region, with cities like Lankaran and Astara relying on these water resources. The border also passes through the Azerbaijani Greater Caucasus mountain range, which includes peaks like Mount Bazarduzu and Mount Shahdagh, and the Iranian Sabalan mountain range, with Lake Urmia and Lake Sevan located nearby. The region's geography has been shaped by the Alborz mountain range and the Caucasus Mountains, which have created a unique ecosystem with a wide range of flora and fauna, including species like the Caucasus leopard and Bezoar ibex, found in Caucasus Nature Reserve and Talysh National Park.

The border region has been influenced by the Silk Road, a major trade route that connected Europe and Asia, with cities like Baku and Tabriz serving as important stops along the way. The region has also been home to various cultural and historical sites, including the Gobustan National Park, Sheki Khan's Palace, and Arg of Tabriz, which reflect the region's rich cultural heritage, with influences from Persian Empire, Ottoman Empire, and Russian Empire.
