Really? Are you aware that plural marriages ended before slavery did? Nice comment though. I guess you don’t value traditional marriage very much, or you might have a teeny weeny inclination to stick up for those who do and actually do something about it.
Nice historical revisionism, freeplancer. (Is this what your Mormon leaders have taught you?) Here, let me provide a proper historical rundown of the period between 1856 and 1910:
1856-1865: The Republican party highlights the defeat of polygamy to be a key plank in its first national platform, characterizing it alongside slavery as one of the "twin relics of barbarism".
Lincoln issued two emancipation proclamation orders in 1862 and 1863, and by July, 1865, 4 million slaves had been set free. The 13th amendment was passed by Dec. of 1865, thereby killing off whatever institutional vestige of slavery.
On the other hand, emancipation for mainstream LDS plural wives came only via death or institutionally ended in the 20th century (& even then it continued thru the LDS "step-daughters", the fLDS).
1899: Mormon congressman B.H. Roberts was voted into office by Mormon Utah but denied his seat because he had taken yet another plural wife after the Mormon "prophet" had supposedly called a halt to the practice earlier that decade.
Guess what happened that year to ensure Roberts wasn't seated? A petition of 7 million citizen signatures was delivered to Congress...covering 28 rolls each two feet in diameter and encased in an American flag. This is 1899, freeplancer...we didn't have even 100-signature petitions being delivered to Congress in 1899 about slavery.
1890-1910: Specifically 220 Mormon men are named by author B. Carmon Hardy (a descendent of one of these men) who took an additional wife between 1890 and 1910. The overwhelming majority of them were not "convicted and sentenced" for their crimes.
And what about the period before plural marriage was publicly (but not privately) called to a halt by Mormon leadership -- the period after slaves were set free?
1865-1890: Hardy, in his book: A Solemn Covenant: The Mormon Polygamous Passage, references how at its late 19th century peak, Mormonism was practiced by 20 to 30% of its membership. (What? Are you trying to claim that 20-30% or more of the South still owned slaves in the late 19th century?)
