Mexico History

Effective family research requires some understanding of the historical events that may have affected your family and the records about them. Learning about wars, governments, laws, migrations, and religious trends may help you understand political boundaries, family movements, and settlement patterns. These events may have led to the creation of records such as land and military documents that mention your family.

Your ancestors will become more interesting to you if you also use histories to learn about the events in which they may have participated. For example, by using a history you might learn about the events that occurred in the year your great-grandparents were married.

Local Histories
Each villa, town, and city has had its own historical chronologist from as early as the conquest and colonial days to the present time. Chronologists are the official historians for the community and are obligated to record its important events. It is wise to visit with the chronologists since they are familiar with the records of the area and can be very helpful.

Some of the most valuable sources for family history research are local histories. They describe the settlement of the area and the founding of churches, schools, and businesses. You can also find lists of early settlers and civil officials. Even if your ancestor is not listed, information on other relatives may be included that will provide important clues for locating the ancestor. A local history may give ideas or suggest other records to search.

Published histories of towns, municipios, and states may contain some histories of families. Some municipio and town histories include separate sections containing biographical information.

In addition, local histories should be studied and enjoyed for the background information they can provide about your family’s way of life and the community and environment in which your family lived.

The Family History Library has some local histories for towns in Mexico. Similar histories are also often available at major public and university libraries and archives.

Bibliographies that list local histories are available for some regions, states, and municipios of Mexico. These bibliographies are listed in the Family History Library Catalog under:

Calendar Changes
The Gregorian calendar is the calendar most often used in the world today. It is a correction of the Julian calendar, which had been used since a.d. 46. Leap years had been miscalculated in the Julian calendar, so by 1582 the calendar was 10 days behind the solar year. In 1582, Pope Gregory XIII issued a papal bill, modifying the calendar to correct the problem. He declared that the day following the fourth of October that year would become the fifteenth of October. Other adjustments were made in the calendar to prevent future leap-year miscalculations.

Spain adopted the new system in 1582, and the Spanish territories in the New World rapidly followed Spain’s example. The Gregorian calendar was adopted in the viceroyalty of Mexico in 1583.
