mistranslation of "szlachta" as "gentry" rather than "nobility". This mistaken practice began due to the inferior economic status of many szlachta members compared to that of the nobility in other European countries (see also Estates of the Realm regarding wealth and nobility). The szlachta included those rich and powerful enough to be great magnates down to the impoverished with an aristocratic lineage, but with no land, no castle, no money, no village, and no subject peasants. Historian M.Ross wrote in 1835: "At least 60,000 families belong to this class, of which, however, only about 100 are wealthy; all the rest are poor." A few exceptionally wealthy and powerful szlachta members constituted the magnateria and were known as magnates (magnates of Poland and Lithuania). Composition Adam Zamoyski argues that the szlachta were not exactly the same as the European nobility nor a gentry, as the szlachta fundamentally differed in law, rights, political power, origin, and composition from the feudal nobility of Western Europe. Feudalism never took root in Poland. The szlachta did not rank below the king, as the szlachta's relationship to the Polish king was not feudal. The szlachta stood as equals before the king. The king was not an autocrat, nor the szlachta's overlord, as szlachta land was in allodium, not feudal tenure. Feudal dependence upon a Polish king did not exist for the szlachta and earlier in history some high-ranking szlachta (magnates) descending from past tribal dynasties regarded themselves as co-proprietors of Piast realms and constantly sought to undermine Piast authority. In 1459 Ostroróg presented a memorandum to the Sejm (parliament), submitting palatines, or Voivodes of the Polish–Lithuanian Commonwealth, receive the title of prince. Sons of a prince were to receive titles of counts and barons. Castellans of the Polish–Lithuanian Commonwealth were to receive the title of count. This attempt to introduce the hierarchy of noble titles common for European feudal systems for szlachta was rejected. The fact the szlachta were equal before the king and deliberately opposed becoming a feudal nobility became a matter of law embedded as a constitutional principle of equality. The republicanism of ancient Rome was the szlachta's ideal. Poland was known as the Most Serene Republic of Poland, Serenissima Res Publica Poloniae. The szlachta, not as a feudal nobility or gentry, but as an electorate, and an aristocracy and warrior caste, with no feudal dependence on a king, exercised supreme political power over
