Reunion of the UPCUSA and the PCUS
As the UPCUSA continued its more liberal shift, talks had begun regarding a merger between the UPCUSA and the Presbyterian Church in the United States, who had split from the main Presbyterian Church in the United States of America in 1861 due to the Civil War. Initially committed to "Old School" Presbyterianism, the PCUS had been beginning a shift towards liberalism in the 1950s and 1960s, including allowing the ordination of women in 1964.
