Guanacaste , a province of Central America, lying between Lake Nicaragua and the bay of Nicoya, and comprising a broken country, thinly populated, and only adapted for grazing. During the dominance of the Spanish crown it was under the political and ecclesiastical jurisdiction of Nicaragua; but after the independence, and the establishment of the republic of Central America, it was set off by the federal congress to the state of Costa Rica. The measure was declared to be temporary, and was against the wishes of its inhabitants. On the dissolution of the federation, Costa Rica asserted jurisdiction over it, on the strength of the enactment of congress; the question led to bitter discussions, until by a treaty in 1858 the greater part of the district was conceded to Costa Rica. Nicaragua still urges her claim to the province. In 1873 telegraphic communication was established between Liber-tad, the capital, and San Jose, the capital of Costa Rica.
