Persians already controlled the Greek cities in Anatolia but the Greeks revolted against their Persian rulers. The Athenians sent warships to help the rebels, but the Persians crushed the uprising. Then the Persian king Darius was angry that the Athenians interfered with his plan so he decided to punish the mainland Greeks.
The Battle of Marathon
Darius sent 600 ships and 20,000 soldiers to battle Athens and the Persians sailed directly to Athens to attack by sea. Then the Athenians ran down the hill prepare to fight but found the Persian foot soldiers out of order. They had an advantage so they attacked and won the battle.
I SEE ATHENS! EVERYONE PREPARE TO FIGHT!
AHH I SEE THEM!
The Greeks wanted to stop the Persians from reaching Athens so they had to attack the ships and cut off their supplies. But then a traitor told the Persians a trail to attack the Greeks from behind. Leonidas knew that they would be surrounded so he and 300 troops remained and fought.
Hey! We should team up to fight the Persians.
The Battle of Thermopylae
Ok let's attack the ships and cut off their supplies.
Yes we should! We'll be stronger!
I know a trail leading around the Greek line so you can attack from behind.
The Battle of Salamis
Oh No! We can't move through this!
The Battle of Platea
WOO!! We won!
In numbers, the two sides were evenly matched with 100,000 men on each side. Once again, the Greeks won against the Persians. Fighting continued as the Greeks wanted to free the city-states in Anatolia from Persian rule. Finally, the Persians and Greeks became allies in 449 BC.
ARGHHH WE LOST
Decline of Persia
We have to make the taxes higher!
Themistocles wanted to battle the Persians in the strait because he believed that the heavy Persian ships would crowd together in the strait, making them difficult to move. The Greeks sank about 300 Persian ships and lost only about 40 ships of their own so the Persian fleet was almost entirely destroyed. But the Persian foot soldiers went to Athens. The Persians found Athens deserted so they set it on fire.
The Persians lost so many battles against Greece and they weren't strong enough to hold up their empire. Because of this, the king heavily taxed the people invaders attacked Persia. Then the Persian empire ended and Alexander The Great took over.
