How many founding members OIC has at the time of its establishment?

The Organization of Islamic Cooperation (OIC) was established in 1969. At the time of its formation, there were **20 founding member countries**.

These countries came together after the fire at Al-Aqsa Mosque in Jerusalem to work for Muslim unity and cooperation in political, economic, and social matters.

Today, the OIC has over 50 member states, but it started with 20. So, the correct answer is **20**.
