Baptistes du Septième Jour
Leeser continued to advocate for the rights of religious minorities within American democracy. In the 1840s and 1850s, Leeser used his "Occident and American Jewish Advocate" magazine to alert the Jewish community to rising threats to their religious freedom. He also allied with other religious minorities, notably Seventh Day Baptists, to advocate against Sunday blue laws that banned work and other activities on the "Christian Sabbath".
