The recognition of the local collectivities and the essential role of democratic society require the clear definition of the term "local collectivity", which would allow the avoiding of ambiguities in its usage. The defining element of the local territorial collectivities is the population, which includes all inhabitants permanently living in the territorial perimeter of the local collectivity. There are identified criteria that allow the establishment of the individuals' belonging to a specific local collectivity. This is very important because the individual's ability to be part of a particular local collectivity gives him the opportunity to take part in local selfgovernment. I insisted on the recognition of the local population as a subject of the local autonomy, and not of the local public authorities elected by the population who are representatives of the local territorial collectivities, while also examining the causes of the population's nonparticipation in local public life.
The present paper wishes to be an inventory of the historical-demographical writings within Romanian landscape. We were able to identify preoccupation for demographic phenomena even since late 19th century, that have grown once with the creation of a discipline of historical demography in the post-war period, especially after the changes that Romania was put througt after Revolution in 1989.
The two documents which are the subject of the present study, made to share property in the event of divorce, help to form an image on various aspects of daily life, poorly known from other sources: household size, land property, earnings in marriage furniture, tools, animals, prices, food, secular and religious involvement of the private life etc. In addition to legal information, both inventories, which stood at the base of documents on which the property was to be divided, reveal another perspective on social history of Arad in the late eighteenth century.
The parish registers of civil status, although the main sources of documentation for historical demography, are used with significant results by the other sciences such as history, ethnography, sociology, anthropology, linguistics, etc.. The perspectives of approaching the rural community and family have expanded considerably using these sources of ecclesiastical origin documentaries. The first researchers who refer to a systematic methodology that uses the parish registers of civil status as documentary sources for the completion of demographic data suggest the use of other sources, hitherto unused for this purpose. They will apply a new method, a modern innovation, the stripping and analysis of parish registers of civil status within the meaning of the reconstruction of demographic events (birth, marriage, death). The family reconstitution method, by analyzing the parish registers of civil status proposed by L. Henry and M. Fleury, has revolutionized the field of study dealing with people. Louis Henry believes that the parish registers of civil status is the ultimate source of information for the pre-state period and this is precisely the reason for which he proposes restoring the family's biological life. Church registers are only able to give us an insight into the family in rural areas, at least for the second half of the XIX century. Church documents, the fundamental sources for researching family life, are of two categories: 1. civil status registers and annual reports of the parishes, 2. Church authorities funds, documents and minutes recorded by the bishops. These documents are complex sources for the researcher interested in historical demography, social history, and the economic history of toponymy, birthdays, etc. Processing the data contained in these records requires a specific methodology. They allow us to observe trends that have occurred on the long-term demographic events such as: birth, marriage or death. These records are presented for a long time as their only source of documentation regarding civil status and demographic events in the life of most people. Researching these records can unveil important features of natural population movement, the phenomenon of birth, of marriage, the divorce or death. Then, an analysis of form and content of these registers can capture the cultural universe of the priests who fill these records. These Church documents proved to be important, especially where other documentary sources (mainly those in the category of records made by the state) have proved insufficient, incomplete and unclear. The parish registers of civil status in this case are suitable for both a qualitative analysis, and a quantitative one at the level of local communities. Beyond their usefulness and significance of documentary source, these documents should be regarded as being subjective because they were managed by priests (every priest is then an exponent to promote demographic and confessional "realities" and such realities were viewed from the perspective of his own religious convictions). The parish registers, however, prove to be the only documents that allow us to penetrate the privacy of individuals in each community. A documentary is also undeniably a good dowry that researchers should promote and use in their research not only locally but also to verify and demonstrate certain behaviours and overall trends.
The ethnic structure of this region has been strongly influenced by the evolution of different historical-geographical, and political factors, but also by the evolution of the confessional structure. Ethnicity, from this point of view, is closely related to religion. What is typical and important to note is that the ethnic structure is very diverse. In addition to Romanians and Hungarians, also Gypsies, Germans, Slovaks, Jews, Ruthenians, and Serbs are present; other ethnic groups are numerically insignificant. For this period we identified two important categories of documents relating to ethnic identity of Transylvanians: 1. records made by the Austrian state authorities; 2. Church documents. They must be viewed and analyzed with great care because they do not correspond directly to the necessity to establish ethnic identities. The documents that are available to us do not allow for an accurate determination of a person's ethnicity. Given the lack of a variable on nationality from the few censuses conducted by the Hungarian State, we propose based on analysis of other documents (particularly those of ecclesiastical origin) to: a) check the mother tongue, b) establish religious identity and c) run an onomastic study.
Mixed marriage is one of the factors providing the link between interethnic and interreligious communities. Ethnic and confessional diversity of the population imposes a communication, an interference of different ethno-confessional communities. As these communities were living together, it was natural that this "cooperation" should be visible in the case of marriage. Given the context, mixed marriages acquired an innate multiculturalism due to the need for living together. The "social barriers" completed the ethnic and confessional differences. The State becoming more and more powerful in time imposed itself and promoted a new perception of mixed marriage through a lay legislation. On the other hand, in the mixed Greek-Catholic and Roman-Catholic communities, inter-confessional marriages were more easily accepted officially as both confessions were under the same hierarchic authority, the Pope. It is important to get a glimpse of the ethnic structures and their dynamics, as well as of the confessional realities to have a clear image in the analysis of interethnic or inter-confessional marriages. Marriage may be one of the social mechanisms to change the demographic volume of certain communities not only quantitatively, but also qualitatively, and to alter traditional spiritual values.
Created by the Hungarian Minister of Instruction and Religion in an attempt to depopulate the Universities of Hungary from the big number of auditors, the Romanian Era of the Law Academy of Oradea began with two academic years, 1919-1920 and 1920-1921, of transition from the Hungarian authorities to the Romanian ones. Due to the efficiency of the Dirigent Council of managing the issues of the Transylvanian education, during 1919 and the first half of 1920, the Academy's activity was not interrupted. The students could continue the studies in similar conditions as those existing before 1918, fact that helped many of them sustain both, the main exams, the final state ones and those of Justice. At the end of the three transitions years, the education institution of Oradea was able to begin the academic year 1921-1922 in normal conditions.
