In the period between the wars, a number of small wars and conflicts racked the region. Some of these conflicts became proxy wars among great powers. For example, long time allies Germany and the United States saw a frosting of their relations in the 1920 when each intervened in a border dispute between Colombia and Venezuela. The Freedom Party of the Confederate States often sent mercenaries to participate in the various wars Latin America experienced after the Great War had concluded. These mercenaries gained valuable combat experience, which they used in the Second Great War.
