In early cases of women's suffrage, only those women who met certain requirements were given the right to vote in certain kinds of elections. In Sweden, there was conditional women's suffrage during the Age of Liberty (1718–1771). Unmarried women who owned property could vote in New Jersey from 1776 to 1807. In the 1792 election in Sierra Leone, all heads of household—one-third of whom were women—could vote.
