Many early socialists were also nationalists. The earliest forms of nationalism had lots of socialist features. In this period, political thinkers who thought that ethnic groups should not be oppressed by other ethnic groups thought also that 'normal folk', the backbone of society, like workers and peasants, should not be oppressed by higher social classes like rich people. They also thought that it is wrong for somebody to live in great welfare that is made of the hard work of others, or the oppression of others. The ideology is that the social classes should work together and have a common goal that aims for the good of everyone. These goals can be called "national interest".
