Short-lived Republics are political entities that declare themselves as republics but do not last long due to various challenges. These challenges can include internal conflicts, lack of popular support, or external pressures from neighboring states. Often, they arise during periods of political upheaval or revolution, aiming to establish democratic governance. Examples of short-lived republics include the Roman Republic during its early years and the Hungarian Republic of 1918-1919. These republics may inspire future movements but often struggle to maintain stability and governance, leading to their eventual dissolution or transformation into other forms of government.
