In 1988, Islam became the state religion of Bangladesh.
But since then, there has been a movement to overturn that decision.
A court petition that was filed nearly 30 years ago is being heard on Monday.
Supporters argue the decision to designate Islam as the state religion was "illegal" in the first place and goes against the government's efforts to promote a secular state.
The issue has become even more relevant in light of recent attacks against atheists and religious minorities.
Some 90 percent of Bangladesh's population is Muslim, while 8 percent are Hindu and 2 percent is made up of other religions.
So what will this case mean for Bangladesh and its state religion?
And will it help protect religious minorities?
