Nicoya geographically speaking was made of the lands located west from the Tempisque River to the Pacific Ocean, and then north of the river El Salto all the way into the river La Flor and Lake Nicaragua, which was the border with the Province of Nicaragua.
This territory enjoyed considerable autonomy, even in civil and administrative depended on Guatemala, the Captaincy. However, by the closeness with the Province of Costa Rica, specifically with towns of Puntarenas, Bagaces and Las Cañas, it established business relationships and closeness with the lifestyle of Costa Ricans.
Therefore, Nicoya, during the Colony, held a very special status. It was a territory that belonged neither to Nicaragua nor to Costa Rica. Commercially speaking, important links existed with Costa Rica.
In 1812 the Province of Costa Rica needed to send a deputy to the courts of Cadiz. Since the Costa Rican population was small, the Province had Nicoya joining temporarily, so that the minimum population required to appoint such a representative was achieved. With this union the priest Florencio del Castillo became the representative for the Province of Costa Rica in the Courts of Cadiz.
When independence was declared in Central America, on September 15, 1821, Nicaragua turned its interest in Nicoya. Since Nicaragua was a country with many internal problems, becoming a part of Nicaragua was not appealing to Nicoya, forcing Nicoya to make a decision as to what country to be a part of. Therfore, Costa Rica was the best option.
The relationship with Costa Rica favors the union made with this territory since commercial ties were very favorable and integration complemented the economic policy, which was developed years before that.
Under this situation , the inhabitants of Nicoya agreed to hold an open meeting to define their situation. They therefore decided to join the Province of Costa Rica on July 25, 1824, under the motto “From the Homeland by our will”, as they were the inhabitants of Nicoya who decided to annex the province of Costa Rica.
Therefore, it should always be the Annexation of Nicoya to the Province of Costa Rica, never the annexation of Guanacaste.
