The United States of San Esteban (Castilian: Estados Unidos de San Esteban), or San Esteban for short, is an island country located in the Sea of the King, bordered by the Atlantic Ocean to the north, and shares maritime borders with Guantanamo, Steenland, and Heriorena. Geographically, it is part of the Columbian continent. It is the second-largest island country in the Sea of the King, behind Champlain. The official languages of the country are Castilian and Hungarian, though Castilian stands as the plurality language. Additional languages include Arawak and Taino. The majority of the population lives in the capital of San Francisco, located on the country's eastern coast.

The native Taíno people had inhabited Hispaniola before the arrival of Europeans, dividing it into five chiefdoms. While they may have interacted with Malian traders during the early colonization of the New World there was no significant colonial settlement on the island prior to 1429. That year, Hungarian explorers, following the Portuguese route, landed on the island, and immediately began a policy of enslavement of the native peoples and population of their territories with their own settlers. Consequently, the region became the first permanent settlement by European powers on the continent of Columbia, despite persistent disputes over the island between Hungary and Castile. Under Hungarian rule, the island was known as Zöldmezők. During the War of the Hungarian Succession in 1725, Castile seized control of the island briefly, but were repulsed by a revolutionary movement pledged to King Michael I's brother Joseph. A brief "Republic of Zöldmezők" was declared from 1726 to 1752 under a rump parliamentary government, before Castile permanently occupied the island again in 1753. An immediate influx of Castilian settlers displaced the Hungarian populations on the island, moving them inland into the rural interior of the country. In 1818, the Estebane War of Independence expelled Castile from the island, leading to the proclamation of a second republic under the Castilian elite.

San Esteban transitioned towards democracy in the 1880s, due to the dominance of its Liberal party in presidential and legislative politics. It secured notable trade deals with other economies on the continent, and grew wealthy through international trade. During the Third and Fourth Great Wars, it retained neutrality but traded with both sides. A policy of neutrality during the Cold War ended following an invasion by the United States in 1961, under false claims that the government under President Víctor Raúl Haya de la Torre possessed nuclear weapons and ties to Germany. A brief period of occupation and resultant political instability led to a new constitution in 1966, which granted rights to the island's Hungarian ethnic population.

San Esteban is a premier destination in the Sea of the King, renowned for its year-round golf courses and resorts. This geographically diverse country boasts the Sea of the King's highest mountain peak, Isten Csúcsa, as well as its largest lake and lowest point, Lake Bela. The island enjoys an average temperature of 26°C (78.8°F), along with significant climatic and biological diversity. It is also famed for hosting the New World's first cathedral, castle, monastery, and fortress, all situated in San Francisco's Colonial Zone, a World Heritage Site.
