Lisbon
Lisbon is one of the oldest cities in the world, and one of the oldest in Western Europe, predating other modern European capitals such as London, Paris, and Rome by centuries. Julius Caesar made it a municipium called "Felicitas Julia", adding to the name "Olissipo". Ruled by a series of Germanic tribes from the 5th century, it was captured by the Moors in the 8th century. In 1147, the Crusaders under Afonso Henriques reconquered the city and since then it has been a major political, economic and cultural centre of Portugal. Unlike most capital cities, Lisbon's status as the capital of Portugal has never been granted or confirmed officially – by statute or in written form. Its position as the capital has formed through constitutional convention, making its position as "de facto" capital a part of the Constitution of Portugal.
Lisbon, New York
By some accounts, the town is named after Lisbon, the capital of Portugal. However, the 1810 US Census for the town shows the town's name as Lisburn, which is a city located in Northern Ireland adjacent to the capital of Belfast. Belfast was the birthplace of Alexander Macomb, the prosperous New York City merchant of Loyalist sympathies. Earlier in 1791, he purchased much of Northern New York along the St. Lawrence River and Lake Ontario, which the state had released for public sale after cession of the land by the Iroquois. With partners, Macomb sold the land for development.
