The term anno Domini is Medieval Latin and means "in the year of the Lord", but is often presented using "our Lord" instead of "the Lord", taken from the full original phrase "anno Domini nostri Jesu Christi", which translates to "in the year of our Lord Jesus Christ".
The Navigation Acts (1651, 1660) were acts of Parliament intended to promote the self-sufficiency of the British Empire by restricting colonial trade to England and decreasing dependence on foreign imported goods.
