<span>Primary source.
A primary source is a historical source that originated at the time of the events by people directly participating in or affected by the events. In the case of researching persons in history, a primary source would be material from those persons themselves or from others in direct contact with them. Primary means first, and so these are the first sources of historical information.
Secondary sources are the history accounts or analyses written by others based on what is seen in the primary sources. Primary sources can be things like letters, official documents, diaries, interviews, contemporary newspaper accounts of events, as well as photographs (or contemporary paintings) and other artifacts from the person or event being studied.
Note that primary sources can be biased in the same way that all sources can be biased. If you were studying the Dakota Conflict, for instance, between white settlers and Native Americans, the sources stemming from the two sides of the conflict will have differing points of view.</span>

Explanation:
<span>Some important results of the Christian crusades in Europe were that Italy was united into one nation, the Turks lost interest in Constantinople, serfdome declined in western Europe and the Roman and Greek churches were united. I thought that the Crusades helped to unite Italy but at least they fostered trade between Italy and the muslim countries, spurred shipbuilding and gave impetus to the development of banking facilities so I believe these factors probably favored greater unity of the nation of Italy.The hegemony of the Roman Catholic Church in Italy as a result of the crusades would most likely increase Italian unity as well.
