War unsettles your life and someone persecuting you unsettles your life. But they do so for different reasons. The question of religious freedom pertains to your condition as a religious believer within a single dimension or sphere of sovereignty. In other words, you are a member of a state, and your freedoms are jeopardized by an organization or state that has sovereignty over you. Religious wars, on the other hand, are an engagement across the boundaries of sovereignty.
Religious freedom is a modern concept that is derived from emerging concepts of secular governance.
The idea of human rights and religious freedom is a modern and borderline nonreligious notion. Religious wars, I would contend, are a pre-modern phenomenon. Most religions do not have the instruments of war at their disposal. Probably Muslim countries are the exception. The Vatican happens to be a state, but they don t have the divisions.
