There’s been an armed conflict just across Malaysia’s northern border for more than 20 years.

But to understand why Pattani, Yala and Narathiwat remain affected by violence today, you have to go back more than a century — to the history of Patani and how the modern Malaysia-Thailand border came to be.

And Malaysia now plays a role in trying to bring the conflict to an end.
