Battleship Potemkin/Bronenosets Potyomkin (1925)

1905. There is a general feeling of revolution amongst the Russian populace against the Imperial rulers. This feeling is slow to reach the crew of the battleship, Potemkin. However, the crew eventually does rebel against their Imperial ruled officers for what they see as the poor conditions aboard, namely the provision of maggot infested rotting meat as their food. This mini-revolution on board leads to a confrontation between the officers and crew. News of the result of this confrontation hits the streets of Odessa as the Potemkin sails into port. The fight on board the Potemkin makes its way to the streets of Odessa as civilians want to show their support for their brothers on board. This situation leads to further actions by the Imperial army, both against the Russian civilians in Odessa as well as against the Potemkin crew.
