Greece is a country located in southeastern Europe. It is bordered by Albania, Bulgaria, North Macedonia, and Turkey. Greece has a long and rich history, and its culture has had an influence on much of the world. The country is home to a variety of landscapes, including mountains, islands, and beaches. Greece is known for its food, including feta cheese, olives, and moussaka. It is also known for its ancient sites such as the Acropolis in Athens and the Oracle at Delphi.

The Second Persian invasion of Greece occurred in 480 BC during the Greco-Persian Wars. It was led by Xerxes I of Persia, who sought to conquer all of Greece. The invasion was a direct, if delayed, response to the defeat of the first Persian invasion of Greece (490–479 BC) at the Battle of Marathon, which ended Darius I's attempts to subjugate Greece. After Marathon, Xerxes had assembled an enormous army and navy, and set out to conquer all of Greece. He was decisively defeated by a Greek alliance at the Battle of Salamis in late 480 BC, and his army was almost destroyed. The following year, 479 BC, saw a Greek army decisively defeat the Persian forces at the Battle of Plataea and end the invasion.

The Persian invasion was a direct consequence of the defeat of Darius I's first attempt to conquer Greece at Marathon in 490 BC. Darius had gathered an immense army and navy for that initial campaign but failed to complete his objective due to various factors including poor planning and bad luck. After this failure he decided to gather another large force for a second attempt at conquering Greece. This time he would have enough men and resources for a successful campaign.

Xerxes I had inherited his father's throne in 486 BC after Darius' death and immediately set about gathering an even larger force than before for his planned invasion of Greece. He amassed an enormous army consisting of over 200,000 infantrymen and 80,000 cavalrymen as well as 1,000 triremes (warships with three banks of oars). He also gathered support from many allies including Egypt and Babylonians who provided him with additional troops and ships respectively.

In 480 BC Xerxes launched his campaign against Greece by crossing the Hellespont (modern day Dardanelles) with his massive army and navy. His forces were met by a coalition led by Athens which included Sparta, Corinth, Thebes as well as other Greek city-states. The Greeks were greatly outnumbered but managed to hold their own against Xerxes' forces in several battles including Thermopylae where 300 Spartans famously held off thousands of Persians until they were betrayed by Ephialtes who revealed a secret passageway through which Xerxes' troops could attack them from behind. Despite this setback however, the Greeks managed to win several victories against Xerxes' forces such as at Salamis where they managed to destroy much of his navy despite being heavily outnumbered once again due to their superior tactics and knowledge of local waters.

The final battle between Persia and Greece took place at Plataea in 479 BC where Xerxes' remaining forces were decisively defeated by an alliance led by Athens which included Sparta as well as other Greek city-states such as Thebes and Corinth among others. This victory marked the end of Xerxes' campaign against Greece thus ending any chance he had for successfully conquering it outright or forcing it into submission through military might alone.

The Second Persian Invasion is widely seen as one of history’s most important conflicts due its implications on both ancient Greek culture as well as international relations more broadly speaking since it marked one instance where Europe successfully repelled an attempted conquest from Asia thus setting up centuries worth of cultural exchange between East and West that continues up until today
