paragraph_text: Hellenistic kingdoms
  
  Alexander's most immediate legacy was the introduction of Macedonian rule to huge new swathes of Asia. At the time of his death, Alexander's empire covered some 5,200,000 km (2,000,000 sq mi), and was the largest state of its time. Many of these areas remained in Macedonian hands or under Greek influence for the next 200–300 years. The successor states that emerged were, at least initially, dominant forces, and these 300 years are often referred to as the Hellenistic period.
  
  The eastern borders of Alexander's empire began to collapse even during his lifetime. However, the power vacuum he left in the northwest of the Indian subcontinent directly gave rise to one of the most powerful Indian dynasties in history, the Maurya Empire. Taking advantage of this power vacuum, Chandragupta Maurya (referred to in Greek sources as "Sandrokottos"), of relatively humble origin, took control of the Punjab, and with that power base proceeded to conquer the Nanda Empire.
