For several decades, polygamy was preached as God's law. Brigham Young, the Prophet of the church at that time, had quite a few wives, as did many other church leaders. This early practice of polygamy caused conflict between church members and the wider American society. In 1854 the Republican party referred in its platform to polygamy and slavery as the "twin relics of barbarism." In 1862, the U.S. Congress enacted the Morrill Anti-Bigamy Act, signed by Abraham Lincoln, which made bigamy a felony in the territories punishable by $500 or five years in prison. The law also permitted the confiscation of church property without compensation. This law was not enforced however, by the Lincoln administration or by Mormon-controlled territorial probate courts. Moreover, as Mormon polygamist marriages were performed in secret, it was difficult to prove when a polygamist marriage had taken place. In the meantime, Congress was preoccupied with the American Civil War.
