"Modern Feminism is generally agreed to have come in three 'waves'.
First Wave Feminism focused on the legal rights of women and traditionally starts with the publication of Mary Wollstonecraft's “A Vindication of the Rights of Woman” in 1792 and culminates with the passage of the Nineteenth Amendment of the US Constitution in 1920 which gave women the right to vote.
Second Wave Feminism started in the Nineteen Sixties, and only really flourished until the mid Nineteen Seventies, focusing upon the socio-cultural perception of women and how that effects women's rights and opportunities.
As most of these issues are still very much unresolved, The Second Wave has not really ended; it merely became diffused by the political and economic conditions of the times.
Third Wave Feminism has a much more complicated pedigree. Depending upon who's talking, it either started in the mid Eighties or early Nineties. It evolved from, and yet is also in reaction to, The Second Wave. It's 'focus' is extremely diverse, to the point where I would say it has no real focus. Its overall issues are about class, race, and gender identity as they relate to 'women's issues'.
Whatever Fourth Wave there may be will would be one that somehow emerges from this often bitter struggle between the Second and Third Waves.
It is my belief, with which E concurs, that these issues are essentially unresolvable inside of the Modern Corporate Marketing Culture, a 'culture' that co-opts every single part of these movements almost as soon as they manifest in order to 'sell product', a practice which allows Patriarchy to 'divide and conquer' while simultaneously profiting financially from the strategy.
Hence the need for a Fifth Wave “that it leaps ahead...to an entirely new construct,”"
