Aruba

Aruba, officially the Country of Aruba, is a constituent island country within the Kingdom of the Netherlands, in the southern Caribbean Sea 29 kilometres (18 mi) north of the Venezuelan peninsula of Paraguaná and 80 kilometres (50 mi) northwest of Curaçao. In 1986, Aruba became a constituent country within the Kingdom of the Netherlands and acquired the formal name the Country of Aruba.

Aruba has an area of 179 km² (69.1 sq mi). Aruba measures 32 kilometres (20 mi) in length from its northwestern to its southeastern end and is 10 kilometres (6 mi) across at its widest point. Aruba is geologically located in South America, lying on the South American continental shelf. Alongside Bonaire and Curaçao, Aruba forms part of an island group referred to as the ABC islands. The Dutch Caribbean encompasses the ABC islands along with the other three substantial islands, the SSS islands. In contrast to much of the Caribbean, which experiences humid tropical climates, Aruba has a dry climate with an arid xeric landscape. The relatively warm and sunny weather persists throughout the year.

With a population of 108,880 (excluding undocumented immigrants), Aruba is home to about one-third of the total population of the Dutch Caribbean. As one of the four countries in the Kingdom of the Netherlands, alongside the Netherlands, Curaçao, and Sint Maarten, Aruba shares Dutch nationality with its citizens. Aruba lacks administrative subdivisions but is divided into eight regions for census purposes with Oranjestad as its capital.

The name Aruba most likely came from the Caquetío Oruba which means "well situated island", seeing as it was the Caquetío who were present on the island when Alonso de Ojeda arrived in the 16th century. Between 1529 and the 1648 Treaty of Westphalia, the name "Isla de Oruba" was used for the island by the Spanish. The island was ceded to the Dutch, and gradually its name was changed to Aruba.

There were many different names for Aruba used by other Amerindian groups, all of which could have contributed to the present-day name Aruba. Another Caquetío name for the island was Oibubia which means "Guided island". The Taino name for the island was Arubeira. The Kalinago also had two names for the island Ora Oubao which means "Shell island" and Oirubae which means "Companion of Curaçao".

A common misconception is that the name "Aruba" came from Oro hubo, (Spanish for "There was gold once"). However, the Spanish declared these islands islas inútiles, meaning "useless islands", due to their apparent lack of mineral wealth. It was not until 1824 that gold was discovered on Aruba by a 12-year-old herder named Willem Rasmijn, leading to the Aruban Gold Rush.

In Aruba's prehistoric era, there were distinct periods: the Archaic or Pre-Ceramic and the Neo-Indian or Ceramic (Dabajuroïd)  period. The Archaic occupation of Aruba continued well into the first millennium AD, which is relatively late compared to other parts of the insular Caribbean. The archaic lifestyle revolved around a food economy based on fishing, hunting, and gathering, with a strong emphasis on marine resources. Ceramics were absent, as was horticulture and agriculture. Weapons and tools were predominantly crafted from stone. Sharp-edged ax blades, chisels, and knives were commonly used, with the knives distinguishable by their elongated shape and flat blades.

One notable site, Sero Muskita, yielded a tool that is older than other archaic age sites on the island. The finishing techniques and shape of this tool resembles one found at Arikok, suggesting a date before approximately 2000 BC. The presence of these tools on the island may be from occasional visits from the mainland. In total, 33 archaic age sites have been identified on Aruba.
