This analysis is related to the system of civilians’ wartime contributions for the defence of the state in the Second Polish Republic. The system of wartime contributions gave the State the right to demand these contributions from the population, and in particular to demand handing over to the State, against payment, property or the right to use movable and immovable property directly or indirectly needed for the purposes of supplying the army and defending the State, but only when a war broke out or when partial or general mobilisation was ordered. The author analyses only one type of the system of wartime contributions understood in this way, namely contributions involving the obligation to hand over draught animals and carts upon the announcement of mobilisation or the outbreak of war. The article draws attention to the first legal regulations in the field of wartime contributions in force on the territory of a reborn Polish State, and in particular to the first legal acts relating to handing over draught animals and carts.
