States of the Holy Roman Empire: Quick Reference
This page summarizes the three main categories of Imperial Estates (Reichsstände)—the political communities that were immediate (reichsunmittelbar) to the Emperor and held a seat and vote in the Imperial Diet (Reichstag).
TL;DR
The Imperial Estates fall into three buckets: Secular principalities, Ecclesiastical principalities, and Imperial (Free) Cities. Together they composed the Diet; immediate groups without a seat (e.g., Imperial Knights) are not counted among the Estates.

Mediatized or subject territories: Lordships subordinated to an Estate (i.e., not immediate) are not Estates.
