It's been seven years since TLC's Sister Wives premiered, and the polygamous Brown family has gone through a lot of changes. But family patriarch Kody Brown and his four wives — Meri, Janelle, Christine, and Robyn — have never shied away from defending their beliefs, even though they're controversial.

The large clan belongs to the Apostolic United Brethren — which is a sect of the Fundamentalist Church of Jesus Christ of Latter-Day Saints (FLDS) or Mormon religion that allows followers to practice polygamy. As Kody likes to say, "Love should be multiplied, not divided." While they used to reside in Utah — a state whose population is nearly 50 percent Mormon — they lived in fear of being arrested because of strict anti-polygamy laws. So in 2011, the gang relocated to Las Vegas so that they wouldn't have to hide their unconventional lifestyle.

"We did not know how aggressive the district attorney would be, so we didn't want him finding out that we were leaving the state," Kody said in a 2015 interview with Oprah. The five adults and 18 children were forced to pack up their belongings in just three days.

Kody explained that the decision to move was a difficult but necessary one. "There was an immense amount of peace that we felt in arriving to Las Vegas," he added. "It was like, 'Okay, this is our new home and here we believe we will experience freedom.'" Scroll down to see the entire Brown family then vs. now!
