After the Civil War, local Masonic orders began to construct meeting halls. Having met in secret for so long, their presence had become less noticeable. With the construction of meeting halls and temples, however, anti-Masonic sentiment rose again. By the early 1870s, religious anti-masonry was on the upswing. Some Christian leaders believed that Masonry was undermining the political and religious foundations of the nation, and some of them called for each religious denomination to ban Masons from their membership. The United Brethren, United Presbyterians, and Conservative Quakers prohibited any Mason from being a member, and many individual Baptist and Congregationalist bodies did so without the nationwide blessing of their denominations.
