Context paragraphs:
Allgemeines bürgerliches Gesetzbuch: The Allgemeines bürgerliches Gesetzbuch (ABGB) is the Civil Code of Austria, which was enacted in 1811 after about 40 years of preparatory works.  Karl Anton Freiherr von Martini and Franz von Zeiller were the leading drafters at the earlier and later stages of the draft.  Comparable to the Napoleonic code, it was based on the ideals of freedom and equality before the law.  It was divided into three major segments, following the Roman law segregation methods.  It was modernized during the First World War.  ABGB continues to be the basic civil code of Austria to this day and it is also still the basic civil code of Liechtenstein.  Besides Austria, its influence persists in other successor states of Austria-Hungary.  In the Czech part of Czechoslovakia (The Slovak part used Hungarian customary law) it was in effect until 1951, although it had been novelized multiple times, until it was replaced by the civil code from 1950.

Civil Code of Quebec: The Civil Code of Quebec (CCQ, French: "Code civil du Québec" ) is the civil code in force in the province of Quebec, Canada, which came into effect on January 1, 1994.

Salic law: Salic law ( or ; Latin: "Lex Salica" ), or Salian Law, was the ancient Salian Frankish civil law code compiled around AD 500 by the first Frankish King, Clovis.  Recorded in Latin and in what Dutch linguists describe as one of the earliest known records of Old Dutch, perhaps second only to the Bergakker inscription, it remained the basis of Frankish law throughout the early Medieval period, and influenced future European legal systems.  The best-known tenet of the old law is the principle of exclusion of women from inheritance of thrones, fiefs and other property.  The Salic laws were arbitrated by a committee appointed and empowered by the King of the Franks.  Dozens of manuscripts dating from the 6th to 8th centuries and three emendations as late as the 9th century have survived.

Civil Code of Romania: The Civil Code of Romania ("Codul civil al României", commonly referred to as "Noul Cod Civil" – the New Civil Code, officially Law no. 287/2009 on the Civil Code) is the basic source of civil law in Romania.  It was adopted by Parliament on 17 July 2009 and came into force on 1 October 2011.  It replaced the Civil Code of 1865 as well as the Commercial Code of 1887 and the Family Code of 1954.

Civil Code of Lithuania: Lithuanian Civil Code from 18 July 2000 ("Lietuvos Respublikos civilinis kodeksas, LR CK") is Civil Code of Lithuania.

West Galician Code: The West Galician code (also The civil code of Western Galicia, German: "Westgalizische Gesetzbuch, "rarely" — Bürgerliches Gesetzbuch von Westgalizien" ) was a civil code created in the 18th century and introduced in West Galicia, an administrative region of the Habsburg Monarchy, created after the Third Partition of Poland, prior to the introduction of ABGB, the civil code of Austria.  It contained little in the way of solving feudal-class problems and was based on the laws of nature.

Civil Code of 1734: The Civil Code of 1734 (Swedish: "1734 års lag"), was passed by the Swedish Riksdag of the Estates in 1734, and put in effect after it had been ratified by Frederick I of Sweden 23 January 1736.  It became the foundation of the later civil code in Sweden as well as in Finland, which was then a Swedish province, though many alterations have been made since.  The current Swedish Code of Statutes is founded on the civil code of 1734.

Civil code: A civil code is a systematic collection of laws designed to comprehensively deal with the core areas of private law such as for dealing with business and negligence lawsuits and practices.  A jurisdiction that has a civil code generally also has a code of civil procedure.  In some jurisdictions with a civil code, a number of the core areas of private law that would otherwise typically be codified in a civil code may instead be codified in a commercial code.

Napoleonic era: The Napoleonic era is a period in the history of France and Europe.  It is generally classified as including the fourth and final stage of the French Revolution, the first being the National Assembly, the second being the Legislative Assembly, and the third being the Directory.  The Napoleonic era begins roughly with Napoleon Bonaparte's "coup d'état", overthrowing the Directory, establishing the French Consulate, and ends during the Hundred Days and his defeat at the Battle of Waterloo (9 November 1799 – 28 June 1815).  The Congress of Vienna soon set out to restore Europe to pre-French Revolution days.  Napoleon brought political stability to a land torn by revolution and war.  He made peace with the Roman Catholic Church and reversed the most radical religious policies of the Convention.  In 1804 Napoleon promulgated the Civil Code, a revised body of civil law, which also helped stabilize French society.  The Civil Code affirmed the political and legal equality of all adult men and established a merit-based society in which individuals advanced in education and employment because of talent rather than birth or social standing.  The Civil Code confirmed many of the moderate revolutionary policies of the National Assembly but retracted measures passed by the more radical Convention.  The code restored patriarchal authority in the family, for example, by making women and children subservient to male heads of households.
