Alexander in India
In 325 BC, Alexander the Great conquered northern India. Alexander was a Macedonian (and therefore an Indo-European) king. Alexander was conquering the whole Persian Empire, and he conquered northern India (modern Pakistan) as part of that - this land had already been part of the Persian Empire. Alexander didn't stay very long though. He stopped when he reached the end of the Persian Empire and left after a couple of years and went back to Babylon, where he died.
Still, Alexander had a lasting effect on India. Alexander left behind several thousand Greek soldiers, to keep an eye on things. These soldiers had with them writers, artists, sculptors, and teachers, and they built Greek cities in Afghanistan and in the Indus valley. The Indians learned about a lot of Greek culture this way, and the Greeks learned a lot of Indian ideas too.
