National Lands or National Estates was the name given to farmlands belonging to Muslim private persons, to the Ottoman state or to Muslim religious institutions and which during the Revolution came under the jurisdiction of the Greek administration. They were located mainly in the Peloponnese and to a lesser extent in central Greece (Rumeli), Euboea and the islands. This is due to the fact that the Revolution in the Peloponnese had been successful and was to a large extent unquestionable, at least up to the landing of Ibrahim's troops (1825). On the other hand, in central Greece - parts of which had been passing back and forth between Greek and Turkish hands - the Muslims had had the opportunity to maintain their rights over the land. After independence, a part of the Muslim holdings was squatted on, while the remainder was sold mostly to large Greek landowners. This favoured the creation of large estates, especially in East-Central Greece and Euboea.

The question of the National Lands and to be more precise that of their distribution kept Greece busy and concerned throughout the 19th century. The intention to distribute the National Lands to people who had participated in the Struggle for Independence had been stated in the national assemblies of the Revolutionary period. After the Revolution the distribution of the National Lands remained one of the constant claims of the veterans who insisted that they should be allocated them as a reward for their contribution to the Revolution. It was, in fact, one of the claims that kept coming up in many of the uprisings that marked the second half of the 1830s. Nevertheless, the question of the National Lands remained pending up until 1871, when Alexandros Koumoundouros proceeded to distribute them.
