Ideal type in the context of "Tripartite classification of authority"

The German sociologist Max Weber (1864–1920) distinguished three ideal types of legitimate political leadership/domination/authority (German: Herrschaft, lit. 'mastership').He wrote about these three types of domination both in his essay "The Three Types of Legitimate Rule", which was published in his 1921 masterwork Economy and Society (see Weber 1922/1978:215-216), and in his classic 1919 speech "Politics as a Vocation" (see Weber 1919/2015:137-138):

1. charismatic authority (character, heroism, leadership, religious),
2. traditional authority (patriarchs, patrimonialism, feudalism) and
3. rational-legal authority (modern law and state, bureaucracy).

These three types are ideal types and rarely appear in their pure form.
