StampNews.com got to know interesting info in the history of philately. A tiny little stamp could cause big trouble, to be precise, one more war. This stamp was issued by Nicaragua in 1937. It featured a map of the country, but it included a large section of land also claimed by neighboring Honduras.
Ownership of the region had long been in dispute between the two countries and remained a source of great contention. In 1906, King Alfonso XIII of Spain decided the matter in favor of Honduras, but Nicaragua refused to acknowledge the decision. Tensions grew in the following years, so when Nicaragua released the stamp in 1937, Hondurans were outraged.
Government officials, newspapers, and radio stations demanded the stamps be recalled and destroyed. Nicaraguan authorities, however, refused and insisted the map was correct. They also pointed out that they had the courtesy to label the area on the stamp as territorio en litigio.
Regardless, in a matter of weeks, anti-Nicaraguan demonstrations erupted in the Honduran capital of Tegucigalpa. Across the border, Nicaraguan radio announcers called for military action, demanding the national army be sent to guard the border region. The public even began a donation drive designed to fund more planes to build up the Nicaraguan Air Force.
At the last minute, the United States, Costa Rica, and Venezuela intervened to defuse the conflict before it escalated into war. Both countries agreed to withdraw their armed forces from the disputed area and stop mobilizing troops. And, naturally, the peace agreement called for withdrawing the offending stamps. They evidently remained in circulation, however, until supplies in private hands ran out.
