Ancient Greece
Siege of the Sogdian Rock
Sogdiana (Present-Day Uzbekistan and Afghanistan)
After Alexander defeated the last of the Achaemenid Empire's forces in 328 BC, he began a new campaign against the various Indian kings in 327 BC. He wanted to conquer the entire known world, which in Alexander's day, ended on the eastern end of India. Greeks of Alexander's day knew nothing of China or any other lands east of India. The Siege of the Sogdian Rock, a fortress located north of Bactria in Sogdiana, occurred in 327 BC.
