A Landtag (Diet) is a representative assembly, with some legislative authority, of a political entity called Land (i.e. state, country, territory) in German.
Ancien Régime
In the feudal society, the formal class system was reflected in the composition of the state's 'representative' assembly (
The States), regardless of its name well described as
estates: it was not intended as an elected reflection of the public opinion, but a fixed expression of the established power as recognized in formal privileges, including the right to seat in person (granted to many aristocrats and prelates, as well as certain cities) or be represented as elector in o college that is entitled to one or more seats.
In some of the
German states that were known as
Land, the name of such estates assembly was Landtag, analogous to the
Reichstag (imperial Diet, mainly comprising most princes of church and hereditary states plus the Imperial Cities). The precise composition obviously varied greatly, and could change over time, as the result of privileges granted or lost, entities split or merged, border changes etcetera.
As Austria and Prussia escaped the French 'exporting the revolution', and Napoleon was happy to maintain satellite monarchies in most German territories under his control (members of the Confederation of the Rhine), the more democratic principles of the Enlightenment would have less effect in the German-speaking lands, or only much later.
