Macedonian invasion

Greek Invasion: -

The prosperity of India was praised by Herodotus, the father of history, and other Greek writers, so Alexander was tempted to invade India. He was also fond of geographical history.
Alexander was the son of King Philip of the Macedonian kingdom. He came to the throne at the age of 20 and reached the western part of India with the desire to become a world champion.
He was helped by King Ambhi of Taxila. So Ambhi is considered to be India's first traitor. Alexander then asked the surrounding kings to join him.
Which was opposed by King Puru (Porus) of the Kekav kingdom and challenged for war. As a result, Puru was defeated in a fierce battle on the banks of the Jhelum river and Puru was abandoned.
The war-weary soldiers no longer allowed Alexander to fight. So Alexander returned home.
Also, according to a legend, after defeating Porus, Alexander was to invade Magadha, which at that time was ruled by Dhananda, king of the Nand dynasty. And this Dhanananda had the largest army in the world at that time. This frustrated Alexander's troops.
The Gandhara Shelley sculpture came to India from the Greek invasion.
Alexander stayed in India for a total of 19 months and fought.
Alexander's invasion marked the beginning of a new chapter in India's trade with the Greeks, as well as the development of astronomy and science.
