Peggy Carter is a fictional character appearing in American comic books published by Marvel Comics. She was created by writer Stan Lee and artist Jack Kirby, making her debut in a single, unnamed panel as a wartime love interest of Captain America in Tales of Suspense #75, published in March 1966. Her backstory was expanded upon just two issues later in Tales of Suspense #77. She was initially conceived to provide a family background for the then-introduced character Sharon Carter, who would later be revealed as her younger sister.
In the original comics, Margaret Elizabeth "Peggy" Carter is depicted as a courageous and resourceful woman who fought alongside the French Resistance during World War II, where she met and fell in love with Steve Rogers, Captain America. Her character embodies the spirit of the era, representing the often-unsung contributions of women in wartime intelligence and combat roles. For decades, she remained a poignant figure from Steve Rogers' past, appearing primarily in flashback sequences that highlighted the life he left behind when he was frozen in ice.
Though a supporting character for much of her publication history, Peggy Carter's legacy within Marvel Comics is significant. She represents a foundational part of the Captain America mythos, symbolizing a lost love and a direct connection to the hero's 1940s origins. Her character was later retroactively integrated into the modern Marvel Universe, with her story being expanded to include her role as a key agent and eventual director of the covert organization S.H.I.E.L.D., long before her grand-niece Sharon Carter took up a similar mantle.
