The article deals with the history of the Thirty Years' War study in the English-language historiography in the 20th-21st centuries. Main characteristics of British historiography in the beginning of Modern History are given. The article gives a brief overview of the main scientific patterns of studying the events of the Thirty Years' War, characteristic of modern English-language historical science. English-language historiography refers to scientific achievements of scholars not only from the United Kingdom and the United States, but also publications of any other European (in this case mainly German, Danish, French and Czech) historians which were published in English and are actively used in historical society. In general, it should be noted that the use of scientific achievements of scholars from other countries in the study of the Thirty Years' War history is quite typical for English-language historiography. This can be explained by the situation when parallelly with this "continental" war came the outcome of the English Civil War, which is steadily more interesting for British historians. The English-language historiography of the Thirty Years' War at the present stage represents both traditional themes of military history and new topics that appeared in the second half of the 20th century. Among the traditional, we can highlight descriptions of various military campaigns and battles, biographies of talented generals, kings and politicians. Among the new, we can note different attempts to expand the chronological and territorial framework of the war, as well as the use of the Thirty Years' War as one of the illustrations of the processes of military revolution or evolution in the European military art and technologies of the 16th-17th centuries. Also, among different modern methods of presenting material, we can underline the "day-by-day" method of submitting material that is popular for today's military history. This method usually does not involve the creation of any original author's interpretations of current events, but instead it suggests a scrupulous presentation of the material with is chronologically divided into day-by-day periods or, for important events, hour-by-hour periods. In general, the historiography of the Thirty Years' War can be characterized as successive, which uses many of predecessors' achievements; on the other hand, there is a high degree of openness in British and American scientific community for foreign researchers and the emergence of a sufficiently large number of fundamentally new areas of research. At the same time, the Thirty Years' War unfortunately is not the most demanded topic of military history; it is substantially inferior to the subjects of the national English and American history, as well as the Modern History.
