Final answer:
The Serbian people were not considered second-class citizens due to most of them being Muslim prior to their revolution.
Step-by-step explanation:
The statement that the Serbian people were considered second-class citizens due to most of them being Muslim prior to their revolution is false.
Prior to their revolution, Serbia, along with Montenegro and Bulgaria, achieved independence from the Ottoman Empire in 1878. While the majority of people in these territories were Orthodox Christians, there were also Muslim populations living in the region.
However, after the death of their leader, Marshall Tito, in 1980, religious differences among the Yugoslavians became increasingly unmanageable, leading to the violent breakup of the country in the early 1990s. The Bosniaks (Bosnian Muslims) now inhabit Bosnia-Herzegovina, while the Serbs (Serbians) are Eastern Orthodox Christians and live in Serbia.
