Hydarnes the Younger vs Mardonius

Hydarnes the Younger was a Persian commander who led forces in Ionia during the Peloponnesian War. He was involved in operations against Greek city-states, supporting Persian interests in the region.

Hydarnes the Younger engaged in diplomatic negotiations with Spartan envoys, seeking to align Persian and Spartan interests against Athens. These talks led to the Treaty of Miletus, which provided Persian financial support to Sparta in exchange for recognition of Persian claims in Asia Minor.

Hydarnes the Younger died around 410 BC. His career exemplified the Persian strategy of using diplomacy and financial support to influence Greek affairs, a policy that continued under subsequent satraps.

Mardonius led a Persian expedition to subdue Thrace and Macedon, forcing them into submission. This campaign secured the northern flank of the Persian Empire and prepared the ground for the invasion of Greece.

Mardonius was a key commander in the first Persian invasion of Greece. He led the Persian army at the Battle of Marathon, where they were defeated by the Athenians and Plataeans. This defeat delayed Persian plans to conquer Greece.

Mardonius was a strong advocate for the second Persian invasion of Greece, urging Xerxes to avenge the defeat at Marathon. His advice influenced Xerxes' decision to launch the massive invasion in 480 BC.

Mardonius commanded the Persian army at the Battle of Plataea, the decisive land battle of the second Persian invasion. The Persian forces were defeated by the Greek coalition, and Mardonius was killed in the fighting. This defeat ended Persian ambitions in Greece.
