Free version of the historical atlas of the Centennia of the American company Clockwork Software. The free version includes a limited (from 1790 to 1820) but interesting period of history - the Great French Revolution, the Second and Third Partition of Poland, as well as the Napoleonic Wars. The program contains historical maps from this period covering Europe, the Middle East and North Africa, which can be viewed year after year, enlarged and printed. Each map can also display the most important historical events that took place in a given year (however, battlefields and military movements are not shown on the maps). The main drawbacks of the program are the interface and maps in English (which, however, should not be a greater problem for students learning English at the same time), as well as minor errors.
