When Did ISKA Begin Sanctioning Muay Thai?
The International Sport Karate and Kickboxing Association (ISKA) was founded in 1986, before officially beginning to sanction Muay Thai in 1991.
Since then, ISKA has promoted and sanctioned professional Muay Thai championship bouts across multiple countries and weight divisions.
How Often Are ISKA Muay Thai World Titles Defended?
As per ISKA’s rules:
- World Champions have the option to make a voluntary title defence within the first six months of their reign.
- After six months, a title defence becomes mandatory. Champions must respond to an official challenge within seven days of receiving it.
- If a Champion does not defend their title for more than twelve months, they may be declared inactive and required to defend against the first qualified challenger.
- If a Champion remains inactive for more than eighteen months, ISKA may declare the title vacant without notice.
How This List Is Compiled
This list is generated using fight records stored in the Muay Thai Records database. It includes every bout in which an ISKA Muay Thai World Title was won or successfully defended, based on officially sanctioned results.
The data is reviewed and updated daily. New title wins and defences are added as soon as verified results are published, ensuring the list remains current and accurate.
Only ISKA Muay Thai World Title bouts are included. Regional, national, and special occasion title contests are excluded, as are exhibitions and unsanctioned bouts.
