Rosalynn Carter, the formidable and influential former first lady, has passed away at 96, as confirmed by The Carter Center. Living with dementia and facing declining health in recent months, she leaves behind a legacy that reshaped the role of the first lady during her husband Jimmy Carter‘s presidency from 1977 to 1981.

Their marriage of over 77 years was marked by a remarkable partnership. Unprecedented for her time, Rosalynn sat in on Cabinet meetings, expressed opinions on controversial topics, and often represented her husband on international trips. Despite facing criticism for her active involvement, she stood as an essential political figure and a significant influence behind the scenes.

Her remarkable impact extended beyond the traditional duties of a first lady, earning her the nickname “the Steel Magnolia” for her unwavering determination, paired with her outwardly unassuming demeanor.

Described as Jimmy Carter‘s “best friend” and an integral part of his life, Rosalynn’s political acumen and assertiveness were acknowledged even by presidential aides, who often sought her opinion before discussing projects with the president himself.

Her pioneering efforts set new standards for future first ladies, emphasizing the powerful role they could play in shaping policy and advocacy. Despite the Carters’ departure from the White House after Jimmy Carter’s defeat in 1980, Rosalynn’s political legacy continued to resonate, reflecting a life dedicated to activism and public service.
