The practice of polygamy expanded as the Latter-day Saints migrated to the Rocky Mountains in 1846. Their move away from Illinois and its state laws that condemned the matrimonies brought them into US territories that did not prohibit it.

While it would be undoubtedly different in the eternal worlds, on earth it is difficult to defend as fair and nonsexist.
