The main point of the research by A. G. Wolfius was the genesis of new ideas in the spiritual sphere. That process he dated to the Late Middle Ages, where the decline of the medieval world had been started. The author saw two main trends of that ideological movement: its was the philosophy of Humanism in the ideology, and religious and ecclesiastic – in the social and political context. He did not draw a strict line between the epoch of the Reformation and the medieval history, offering his own view at the periodization. He talked about the ‘epoch of Humanism and Reformation’, dividing it into two steps. The first one was dated by him up to the mid-sixteenth century; it was characterized with flourishing of Humanism and independent cities, as well as the reformation in its international connections, and the development of capitalism in economics, and social disturbances. The second step was framed by him from the mid-sixteenth century till the end of the Thirty-Years War; it was a period of ‘religious conflicts and wars’, where W, saw three main elements: the Catholic reaction, growing of Absolutism and its role in religious wars, and the religious conflicts intertwined with class interests. He put a special attention at the Augsburg Peace, as a whole-European border in the evolution of the reformation. In spite of the fact, that the author was concentrated at the issues of spiritual processes, he stressed that the ideological factor was not the only one among the formative phenomena of the epoch.
