The document summarizes the history of corporate personhood in the United States, including key Supreme Court cases. It discusses how the 1886 Santa Clara County ruling established that corporations have rights as persons, and how the 2010 Citizens United decision found that restricting corporate political spending violates free speech rights. The decision is controversial as critics argue unlimited corporate money in elections undermines democracy, while supporters see it as protecting free speech. Proposals to reverse the decision include a constitutional amendment or campaign finance reform.
