ENThe Chronicle of Henry of Livonia has been written at the time of the 1225 to 1227, and it is the first entire source of the history, which displays the events in the Baltics at the end of 12th century and beginning of 13th century. Data from the Chronicle of Henry of Livonia is widely analyzed, but it is not done with the aim of understanding the communication of that time. It is important from the aspect of the history of the communication and helps to understand better the society of ancient Latvians and Livs, their mobility and preparedness to communicate with people from other cultures. Baltics, including lands of the ancient Prussians, had remained an insignificant island of paganism, when two Christian churches – Roman Catholic and Greek Catholic (Orthodox) clashed nearby. Since prevalence of the writing is closely linked to conversion to the Christian faith, pagan Baltic nations did not recognize it. To the cultures of this period the characteristic communication is the communication with God – critical community decisions were taken after clarifying the will of God. God's will was clarified by the drawing of lots or with the help of the horse of destiny. Personal communication dominated during mutual interaction. Describing the situation in the Baltics in the 12th / 13th centuries, it is difficult to speak about the mutual interaction of the two or three radically different cultures. Admittedly that Western Christians and the local nations were separated by different structure of the society. However, in other fields such as skills, abilities, mobility, the differences were not large. Eastern Christians, Russians, also did not recognize feudalism in its classical sense. Differences in communication arose not so much in distinctive competences, but in ambitions. The aim of Western Christianity was to reach the subjection of the Baltic nations to the Roman Church.It is achieved not only by conquering "with fire and sword but also through purposeful activity, convincing and conquering the local minds. Russian Orthodox view was not so much related to the spreading of Orthodoxy, but mostly with extortion of taxes, pillaging and provision of trade routes along the river Daugava. Anyway, the Chronicle of Henry of Livonia does not inform about Russian preachers, missionaries, and other techniques of ascendancy, such as plays with religious content. So, the word is absent, just action. Local nations were adapted to new circumstances – either resisted, or looked for allies in both, Roman and Greek Christians. Various military alliances were concluded, Christianity was accepted, dropped, and again accepted. These various primary objectives influence also the mutual communication. Western Christians managed and used a much larger arsenal of ascendancy. It was goal orientated communication with aim of changing the attitude, without disregarding all that was associated with the conclusion of military alliances, gathering of information, operational reaction to the turn of events. This system was more effective, and around the century, the local resistance of the nations of the present Latvia and Estonia were broken. Medieval Livonia was established.Kronikos.
