Because a civil war is war happening within the same country, hence the literal name.
The Indian Removal Act took place in the first half of the 1800s under the presidencies of Andrew Jackson and Martin van Buren and directly led to the Trail of Tears, which resulted in the death of many members of tribes in the American South. It was considered controversial because the Supreme Court ruled in favor of the tribes' cause wherein the state of Georgia (which was actively seeking to evict the Indian inhabitants) was told it had no right to force their removal. Nevertheless, the president ordered their removal.

As states and empires increased in size and contacts between regions multiplied, religious and cultural systems were transformed. Religions and belief systems provided a bond among the people and an ethical code to live by. These shared beliefs also influenced and reinforced political, economic, and occupational stratification. Religious and political authority often merged as rulers (some of whom were considered divine) used religion, along with military and legal structures, to justify their rule and ensure its continuation. Religions and belief systems could also generate conflict, partly because beliefs and practices varied greatly within and among societies.
