5. Margaret Thatcher
Margaret Thatcher’s early political journey was filled with derision and doubt. As a grocer’s daughter with unapologetically firm views, she was often patronized and dismissed by the political establishment. Dubbed the ‘Iron Lady’—originally meant as an insult—her resolute stance drew criticism and ridicule. However, Thatcher defied her skeptics, becoming the UK’s first female prime minister and reshaping British society and politics with her bold policies and tenacious leadership (via The Guardian).
