Landed nobility or landed aristocracy is a category of nobility in various countries over history, for which landownership was part of their noble privileges. Their character depends on the country.
In Poland, szlachta were usually landowners, with magnates being the class of the wealthiest szlachta. Middle and smaller landed szlachta was called :pl:ziemiaństwo|ziemiaństwo/ziemianie, usually translated as landed gentry.
In some places, e.g., in Low Countries before Spanish rule, urban nobility with landed estates was distinct from landed nobility. In general, relations between landed nobility and towns was very complex in Europe.
In India, jagirdar and zamindar were the landed aristocracies, which formed Indian feudalism. Sometimes, they were elevated to the status of 'princes' or 'royalty' owning princely states. Sometimes royal status was also reduced to the status of zamindars. In the south, Nairs constituted the landed gentry and owned vast amounts of land spread out in current day Kerala and Tamil Nadu.
In the Philippines, the Principalía was the ruling and usually educated upper class in the towns of the Spanish Philippines. The distinction or status of being part of the principalía was a hereditary right. This upper class was exempted from tribute to the Spanish crown during the colonial period. The principales traced their origin from the pre‑colonial royal and noble class of Datu and Lakan of the established kingdoms, rajahnates, confederacies, and principalities, as well as the lordships of the smaller ancient social units called barangays in Visayas, Luzon, and Mindanao. The members of this class enjoyed exclusive privileges, including the right to vote, be elected to public office, and be addressed by the title: Don or Doña.
Within certain communities in Nigeria, the reigning monarchs are often vested with inalienable landownership due to their positions, with them either owning tracts of land outright or holding them in trust for their states. Some communities don't follow this pattern, however. In the Kingdom of Lagos, for example, landownership is not traditionally vested in the Oba of Lagos, who is descended from later immigrants from the Kingdom of Benin, but is instead vested in the so-called Idejo class of titled aristocrats, who all claim descent from the earliest Yoruba settlers of Lagos. Some of the more powerful of them have even risen to become subordinate obas under the overlordship of the Oba of Lagos due to this fact. Elsewhere, in Egbaland, the Egba Alake ruling section of the Egba Yorubas is typically considered to be the landowning segment of the clan. Both the ruler, the Alake of Egbaland, and the most powerful Ogboni aristocrats, the Omo-Iya-Marun, have to belong to families from this section.
