Answer:
The right answer is false.
Step-by-step explanation:
To give a categoric answer is very difficult. Arab and Muslim expansion was a long and powerful process. In North Africa, most conversions were voluntary. In Al-Andalus (present-day Andalucía in Spain), Muslims, Christians and Jews lived together rather in harmony and respect under the rule of Islamic rulers. Nevertheless, there are cases of forced conversion into Islam after a military conquest. That´s the case of Bulgaria and some Balkanic nations.
