(KCAU) — Queen Elizabeth II, Britain’s longest-reigning monarch and a symbol of stability in a turbulent era that saw the decline of the British empire and embarrassing dysfunction in her own family, died Thursday after 70 years on the throne. She was 96.

The palace announced she died at Balmoral Castle, her summer residence in Scotland, where members of the royal family had rushed to her side after her health took a turn for the worse.

Lawmakers from Iowa, Nebraska, and South Dakota have released statements on the recent passing of Queen Elizabeth II.

Sen. Chuck Grassley of Iowa

“Queen Elizabeth II was a strong and graceful leader for the better part of a century. As queen, she was a tremendous source of stability and clearly loved the people she served. She’ll forever be a symbol of decency and humanity for the whole world. Queen Elizabeth II leaves a remarkable legacy of duty, honor and service,” Grassley said.
