Defining which countries have been "converted" to Islam is complex because it involves historical processes, varying degrees of religious adherence, and differing legal definitions of a state's relationship with Islam. However, one way to approach this question is to identify countries where Islam is declared the state religion.
The following countries have Islam as their state religion:
- Afghanistan
- Algeria
- Bahrain
- Bangladesh
- Brunei
- Egypt
- Iran
- Iraq
- Jordan
- Kuwait
- Libya
- Malaysia
- Maldives
- Mauritania
- Morocco
- Oman
- Pakistan
- Qatar
- Saudi Arabia
- Somalia
- Tunisia
- United Arab Emirates
- Yemen
It's important to note that the degree to which religious law is implemented varies significantly among these countries. Also, the presence of a state religion doesn't necessarily reflect the religious demographics of the entire population, as religious minorities may exist within these countries. The historical "conversion" process leading to this status also varied greatly in each nation.
