While most Christian denominations did not allow women to preach during the nineteenth century, a few more evangelical Protestant denominations did permit women's preaching. In early-nineteenth-century Britain, the Bible Christians and Primitive Methodists permitted female preaching, and had a significant number of female preachers, particularly among the rural and working-class populations. Some of them emigrated to British colonies, and preached to settlers in colonies including early Canada. By the second half of the nineteenth century these denominations became more institutionalized, and thus less open to women's preaching, although a few women continued to preach in these denominations until the early twentieth century. Later in nineteenth-century Britain the Salvation Army was formed, and from the beginning it permitted women to preach on the same terms as men. These "Hallelujah Lasses", many of whom were working class, were very popular, often drawing huge crowds in Britain as well as in North America. Nonetheless, these denominations remained a minority, and in most Christian churches women remained barred from the ministry into the twentieth century.
