Dear Land of Hope, thy hope is crowned
God make thee mightier yet!
On Sov'ran brows, beloved, renowned
Once more thy crown is set
Thine equal laws, by Freedom gained
Have ruled thee well and long;
By Freedom gained, by Truth maintained
Thine Empire shall be strong
Land of Hope and Glory
Mother of the Free
How shall we extol thee
Who are born of thee?
