How did Morocco avoid European invasion for so long?

Morocco is a country that is located in the Northern corner of Africa. Berbers has always inhabited Morocco and it was also part of the Roman Empire which explains why it was not colonized immediately. The only time when the chaos started to take place was when the Roman Empire fell. There were a lot of vandals who broke into Morocco. Since the country was weak, it was also taken over by the Arabs.

For a long time, Europeans were trying to take over the country but probably because of its high mountains, this place made it harder to reach as compared to the other neighboring countries in South Africa. The culture of Morocco now is diverse because of the colonization that took place.
