The almanacs represented an important source and constituent part of the popular culture in the 'long' nineteenth century. The text focuses on the by now slightly studied almanacs of Czech Protestants and, as a supplement, also contains its register. First Protestant calendars were published after the authorization of Protestant denominations at the end of the eighteenth century, but due to the economic weakness of these minorities soon ceased to exist. The next wave of their publishing was connected with liberalism of the middle of the nineteenth century and the social emancipation of Protestants. But the defeat of the revolution of 1848 again caused their demise. Systematic publishing of Protestant almanacs took place only in the last third of the nineteenth century, when their principal role was the gradual deepening of the confessional consciousness. From the beginning of the twentieth century these almanacs were used in the efforts for uniting of Czech Lutheran and Reformed Churches. This union was realized after the constitution of Czechoslovakia in the year 1918. Later Protestant almanacs were mostly regular ecclesiastical yearbooks without broader implications.
