The wise men were also known as Magi or kings from the East.
It is not clear where they came from exactly - the Bible just says from the east. Some believe they came from Persia (modern day Iran), others from Arabia and others Babylon, since they were noted astronomers.

Again, angels are key to this story, as they appeared to Joseph to warn him that they were not safe in Israel because of King Herod. Because of this dream, Joseph, Mary, and Jesus fled to Egypt.
Herod became enraged that he had been tricked by the wise men, and ordered that all baby boys under 2 years old be killed (this is why it is commonly accepted that Jesus was between 1 and 2 years old when the wise men visited, not in the manger scene).
After some time, an angel appeared to Joseph to tell him that it was safe to return to Nazareth from Egypt.
Notice the parallels and contrasts in this story and the story of the Israelite exodus from Egypt:
