The contribution focuses on the participation of missionaries from the "Bohemian Province" of the Society of Jesus in the colonization of America in the 17th and 18th century, and the representation of the New World in letters and reports sent to the home province. Thanks to the activities of the Jesuits, intensively followed up in their home province, and complemented of course by some other direct and indirect involvement in the process of overseas colonization, the inhabitants of the Czech Lands found themselves integrated into the newly established Atlantic system and participated in the intense interchange of information and cultural influences.
