The correct answer is - Two once mighty empires were collapsing because of internal strife and foreign invasions.
The Byzantine Empire managed to outlive Rome by approximately 1,000 years, but the way in which both, the Eastern and the Western Empire ended is pretty much the same.
Both Rome and Byzantine were very large empires, but as they were nearing their end, they were gradually losing their territories until the only remaining part of the empire was the most important city and the closest area around it.
The fall of these two empires was because of internal strife, where the aristocracy was only concerned about their personal interest and wealth, while totally forgetting the country, but also because of the multiple strong military forces that emerged on the scene and weakened them.

The drafting of the Code was the result of the accumulated experience of generations. A number of sources were tapped in the writing of the Code, including the Coutumes<span>, Roman law, Royal Ordinances, canon law, and Revolutionary law. Predominantly customary or common law prevailed. Customary law supplied the articles dealing with the disabilities of married women, community property, and succession. Roman law was the source for ownership, obligations, contracts and the marriage property system. Royal Ordinances served as the basis for certificates of civil status (the Ordinance of April 1667), gifts wills and entails (the Ordinances of 1731, 1735, and 1747), evidence (the Ordinance of Moulins of 1566 and the Ordinance of April 1667) and the redemption of mortgages (the Edict of 1771). Revolutionary laws were adopted for the age of majority, marriage, and the system of mortgages. The Civil Code enforced the Revolutionary laws dealing with the partition of estates among heirs. Canon law supplied rules dealing with marriage and legitimation. </span>
