On 11 February 1975, Margaret Thatcher etched her name into British political history by defeating Edward Heath to become the leader of the Conservative Party, marking the dawn of a new era defined by her resolute conviction and formidable will.

As the first woman to helm a major political party in the United Kingdom, her victory signalled not just a shift in leadership but a seismic transformation in the ideological fabric of the Conservatives.

Thatcher’s ascent was emblematic of a burgeoning appetite for change within the party ranks, disenchanted by Heath’s faltering grip amid economic turmoil and industrial strife.

Her unapologetic advocacy for free-market policies, fiscal austerity, and individual enterprise would soon reconfigure Britain’s political landscape, heralding the rise of what would come to be known as Thatcherism.
