"Social democratic roots take us back to the two great revolutions in modern western European history. The French Revolution of 1789 paved the way for a political view based on the interests of society, while the industrial revolution created the working class which, challenged by the new company organisations and capitalism, came up with the idea of forming the first trade unions as a means of protecting their interests and ensuring that they were not ignored. Workers did not have status and did not possess land, nor did they have control over the means of production. These are the main principles underlying social democracy in which the development of equality and egalitarianism have played major roles. The article goes on to discuss cause and effect relationships between social democracy and trade unions; the importance of egalitarianism as a linking ideology and practice; the necessity of the acceptance of social democracy as a condition of the existence of trade unions; and the importance of social security as a standard for social democracy and the survival of trade unions.
