Alexander the Great arrived in the area of Afghanistan in 330 BCE after defeating Darius III of Persia a year earlier at the Battle of Gaugamela. His army faced very strong resistance in the Afghan tribal areas where he is said to have commented that Afghanistan is "easy to march into, hard to march out of." Although his expedition through Afghanistan was brief, Alexander left behind a Hellenic cultural influence that lasted several centuries. Several great cities were built in the region named "Alexandria," including: Alexandria-of-the-Arians (modern-day Herat); Alexandria-on-the-Tarnak (near Kandahar); Alexandria-ad-Caucasum (near Begram, at Bordj-i-Abdullah); and finally, Alexandria-Eschate (near Kojend), in the north. After Alexander's death, his loosely connected empire was divided. Seleucus, a Macedonian officer during Alexander's campaign, declared himself ruler of his own Seleucid Empire, which also included present-day Afghanistan.
