Based on the map provided, what are the historical events depicted and where do they take place?

This map depicts historical events related to territorial movements and battles. The key indicates symbols for 'place of battle' (crossed swords) and 'assembly point of troops' (shaded circle). Several locations are labeled, including: * Москва (Moscow): Appears as a significant city, likely a center of power or a target. * Владимир (Vladimir): Another city, possibly part of the same larger political entity. * Серпухов (Serpukhov), Одоев (Odoev), Елец (Yelets): These appear to be smaller settlements or strategic points. * Рязань (Ryazan): A prominent city labeled within the "РЯЗАНСКОЕ" territory. Rivers like the Ока (Oka), Лопасня (Lopasnya), Меча (Mecha), Дон (Don), and Воронеж (Voronezh) are also shown, indicating geographical context for the movements. Arrows suggest troop movements and directions of campaigns. For instance, there are arrows originating from Moscow and moving southwards, and also movements originating from the west towards Moscow. There's also a notable area marked with a '1' and an arrow pointing towards it, possibly indicating a major encounter or a key strategic point in a conflict. Another point of interest is marked with a '4' where several troop movements converge. The map also delineates larger political or territorial entities such as "ВЕЛИКОЕ КНЯЖЕСТВО МОСКОВСКОЕ" (Grand Principality of Moscow), "ВЕЛИКОЕ КНЯЖЕСТВО ЛИТОВСКОЕ" (Grand Duchy of Lithuania), "МУРОМСКОЕ КНЯЖЕСТВО" (Murom Principality), "РЯЗАНСКОЕ" (Ryazan territory), and "ЗОЛОТАЯ ОРДА" (Golden Horde). There are blank fields at the bottom for 'Дата' (Date), 'Участники события:' (Participants of the event:), 'Русскими полками командовал—' (Commanded Russian regiments—), and 'Войсками неприятеля командовал—' (Commanded enemy troops—), suggesting this map is part of an educational exercise to be filled in by a student.
