Periodisation of the Reformation in Riga and Livonia in the history of Latvia and the Church of Latvia is multi-layered. In general history, the issue of the general periodisation of the Reformation has been dealt with in different ways, guided by political and economic tendencies (or their absence), etc., and in general the Reformation fits in the final phase of the Middle Ages, which in Latvia coincides with the end of the Livonian Confederation. From a local point of view, the Reformation of Riga and Livonia was in continuity with the general historical to flow in time of our country, which was then the periphery of Western Europe. The Reformation concludes this stage with an intra-ecclesiastical (theological) choice to remain in the Wittenberg tradition of Catholic Christianity. However, the activities of the Reformation did not run short and are also reflected in the continuity of the Reformation, when, especially as a result of the influence of the Lithuanian–Polish conversion policy, the Roman (so-called Catholic) tradition of Catholic Christianity enters Latgale. Thus, Riga and Livonia were and remained almost unchanged in the status quo of their church state, in which changes were introduced only with the active Reformation of the Pope in the Lithuanian–Polish state almost half a century later.
During the preparation of the article, it has been established that separation of the Reformation as an isolated phenomenon is not justified, unless it is a matter of the history of ideas and theology, since the Reformation undoubtedly brought new, hitherto unusual features to the theology. The changes are political, the top leadership changes, forming a clear periodisation in the history of our country, also with an indirect influence of the Reformation. Whereas there are practically no changes in the economic development of our country. In a much broader context, the uniqueness of the Reformation of Riga and Livonia is that it has been the “flagship” of historical events on three particular occasions.
