Dominionism describes, in several distinct ways, a tendency among some conservative politically-active Christians, especially in the United States of America, to seek influence or control over secular civil government through political action — aiming either at a nation governed by Christians, or a nation governed by a conservative Christian understanding of biblical law.
The origin can be traced back to a specific passage in the King James Version of the Bible:
And God blessed [Adam and Eve] and God said unto them, "Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth."
- Genesis, Chapter 1. King James Bible
