“Women Build Legacy” explores the often-overlooked yet profound impact of women's social engagement on community development and historical progress. By examining various forms of activism, community organizing, and cultural contributions, the book highlights how women have consistently shaped societies. It uniquely uses social engagement statistics—such as likes, shares, and sentiment analysis—to quantify the reach and effectiveness of women's efforts, offering a fresh perspective on historical analysis. This approach challenges traditional narratives and provides a more nuanced understanding of societal evolution by emphasizing women's leadership. The book progresses by first introducing core concepts and the use of social media metrics as a tool for historical analysis. It then delves into specific case studies across different eras and locations, ranging from early suffrage movements to contemporary online activism. Through detailed data analysis, the book reveals patterns and correlations between women's engagement and tangible social outcomes, culminating in a discussion of the implications for current social policy and future research. Ultimately, the book argues that understanding women's historical social engagement is essential for a complete understanding of societal evolution.
