Afghanistan, often called the crossroads of Central Asia, has had a turbulent history. In 328 BC, Alexander the Great entered the territory of present-day Afghanistan, then part of the Persian Empire, to capture Bactria (present-day Balkh). Invasions by the Scythians, White Huns, and Turks followed in succeeding centuries. In AD 642, Arabs invaded the entire region and introduced Islam. | Afghanistan, often called the crossroads of Central Asia, has had a turbulent history.
