Why is "Spanish settlement in Argentina" trending?

Wikipedia Overview

Spanish Argentines are Argentine-born citizens who are predominantly or totally of Spanish descent. The arrival of Spanish emigrants in Argentina took place first in the period before Argentina's independence from Spain, and again in large numbers during the late 19th and early 20th centuries. Between the 15th and 19th centuries, the Spanish Empire was the sole colonial power in the territories that became Argentina after the 1816 Argentine declaration of independence. Thus, before 1850, the vast majority of European settlers in Argentina were from Spain and they carried the Spanish colonial administration, including religious affairs, government, and commercial business. A substantial Spanish descended Criollo population gradually built up in the new cities, while some mixed with the amerindians (Mestizos), with the slave population sub-saharan descended (Mulattoes) or with other European immigrants. Currently, a large part of Argentines can be considered Criollos or Castizos.
