"The first modern socialists were early 19th century Western European social critics. In this period, socialism emerged from a diverse array of doctrines and social experiments associated primarily with British and French thinkersâespecially Robert Owen, Charles Fourier, Pierre-Joseph Proudhon, Louis Blanc, and Saint-Simon. These social critics criticised the excesses of poverty and inequality of the Industrial Revolution, and advocated reforms such as the egalitarian distribution of wealth and the transformation of society into small communities in which private property was to be abolished. Outlining principles for the reorganization of society along collectivist lines, Saint-Simon and Owen sought to build socialism on the foundations of planned, utopian communities."
Straight from the article. Its not about what the term has come to mean in modern day politics but what it literally means. Again communism is a form of socialism. True socialism has never been achieved not true communism.
