The term "Greco-Bactrian" refers to a historical period and region where Greek culture and influence merged with the local traditions of Bactria, an area that is part of modern-day Afghanistan and Tajikistan. This cultural fusion occurred after the conquests of Alexander the Great in the 4th century BCE, leading to the establishment of the Greco-Bactrian Kingdom around 250 BCE. The Greco-Bactrian Kingdom was known for its rich cultural exchanges, including art, architecture, and trade. It played a significant role in the spread of Hellenistic culture in Central Asia and served as a bridge between the East and West, influencing regions as far as India and China.
