In sensitive areas, there are many historical factors that can easily intensify the emotions of local residents. The following are some common aspects.： 1. **Territorial disputes**: Historical territorial changes, boundary division disputes, etc., if they are not properly resolved for a long time, they can easily cause strong emotions and antagonism. For example, some historical territorial issues in the China-India border area have caused tensions many times. 2. **Ethnic contradictions and historical entanglements**: The historical experience of conflicts, oppression, discrimination, etc. of different ethnic groups will become sensitive points that can easily be instigated. For example, the complex historical contradictions and old grievances between some ethnic groups in the Middle East have led to regional turmoil from time to time. 3. **History of religious conflicts**: Past events such as conflicts between different religions, persecution, and competition for religious places in the course of history can be used by those with ulterior motives to provoke emotions. For example, the various religions in the Jerusalem area have complex historical disputes and disputes over the ownership of holy places. 4. **Historical trauma of colonial rule**: In areas that have suffered from colonial rule, the historical pain such as oppression, exploitation, and cultural suppression brought by the colonists can easily be aroused as emotional flashpoints, such as Africa and some areas in Asia that have been colonized. 5. **Controversial interpretation of major historical events**: There are differences in the interpretation of some historical events that have a significant impact. When they are distorted or used unilaterally, they will intensify the emotions of local residents, such as some key events involving the formation of a nation-state.
