Allgemeines Landrecht für die Preußischen Staaten

The General State Laws for the Prussian States (Allgemeines Landrecht für die Preußischen Staaten, often abbreviated to ALR) were an important civil code of Prussia, promulgated in 1794 and codified by Carl Gottlieb Svarez and Ernst Ferdinand Klein, under the orders of Frederick II. The code had over 17,000 articles, and covered fields of civil law, penal law, family law, public law, administrative law etc.

Frederick I of Prussia wanted to create a uniform set of laws, but it was not started until Frederick II. Frederick's idea was not only to create a unified set of laws, but to make them clear and eliminate possible manipulations by different interpretation. A previous attempt, Project eines Corporis Juris Fridericiani (1749–51), by Samuel von Cocceji, proved unsuccessful.

The first version was called the General Code for the Prussian states (German: Allgemeines Gesetzbuch für die Preußischen Staaten, AGB, 1792). The general state laws for the Prussian states were finally codified in 1794 by mainly Svarez and Klein, who were under the orders of Frederick the Great.

The interpretations of the code's usage are contradictory; some interpret the laws as well known for being simple to read and interpret, without much abstract, being rather an every-day regulating laws, but others point out that while the code was written in German, it used an incredibly casuistic and imprecise language, making it hard to properly understand and use in practice.
