What is the context of the radical idea of marrying for love by Stephanie coontz?

In her work, Stephanie Coontz explores the historical evolution of marriage, emphasizing that the idea of marrying for love is a relatively modern concept. Traditionally, marriages were often arranged for economic, social, or political reasons, prioritizing family alliances over personal affection. Coontz argues that this shift toward love-based unions reflects broader societal changes, including the rise of individualism and the pursuit of personal happiness. By examining these dynamics, she highlights how contemporary relationships are shaped by both historical practices and modern expectations.
